Photography in the Field

Last year I bought my first digital camera. Two of the photos in The Roof at the Bottom of the World were made with it. The rest were shot with film. Poor grad student that I was, my first Antarctic season, 1970-71, I didn’t even own a camera, and ended up borrowing one from a friend, a Kodak Pony 135. Because it required a hand-held light meter that I seldom used, I had few photos at the end of the season worth looking at a second time. On the way home that year with some salary earned, I bought a screw-mount Pentax Spotmatic with a 50 mm lens in the Navy store in Christchurch, NZ. This was my camera for about two years, during which I did dissertation research for four months in southern Africa comparing rocks of similar age to my suite in Antarctica. For the following six months, I took a long way home, backpacking from Cape Town to Cairo to Rawalpindi, where I cashed in my return airfare. It was a different world in 1973. The Shah was still in power in Iran and the Russians had not yet invaded Afghanistan. A far out trip if ever there was! I set off for South Africa with 10 rolls of Agfachrome and a vow that I would make them last my time away. This was about one shot per day. In order to give some structure to the resolution, I decided that every shot I took should have some geology in it, something that either pertained to my research or would illustrate something geological for a future lecture, if I made it as a professor. It took tremendous discipline, parsimony to the max, and it has influenced my approach to photography ever since (ever since, that is, until I started shooting digital, where instead of every push of the shutter costing 75¢, the more you shoot the less each shot has cost when divided into the original price of the camera.) The other thing that I took with me that trip was a 100-300 mm zoom lens, a huge barrel of a thing, that a fellow grad student had offered to me for $25 just before I left. When I got home I was sold on zoom lenses and fed up with the screw mount. At about that time, the 3/4 size 35 mm SLR’s were coming onto the market, and I bought a Pentax MX, which I have used ever since. With thru-the-lens metering and everything else manual, I found it to be the perfect field camera, lightweight, tough, and easy to use even when wearing gloves. Given the kind of research that I do, which involves a lot of strenuous hiking, sometimes on steep terrain, I quickly decided that I didn’t have time to take my camera out of my backpack every time that I wanted to shoot a photo. The old style parkas issued by the U. S. Antarctic Research Program offered a solution. Complete with genuine, wolverine ruff and a tunnel hood, these garments had a buckle across the front attached to elastic straps. I was able to wear my camera around my neck while hiking, and to keep it from swinging by putting it under the elastic buckle. I kept the camera in its carrying case, and had an extended cover with a zipper on it for zoom lenses. This arrangement worked well except that I still had to change lenses between wide-angle and telephoto shots.

Finally (in the mid 90’s, I think it was,) Tamron offered a 28-200 mm zoom lens that was about three inches long, liberating me from the need to change lenses ever again. I bought a holster case that I strapped firmly on my chest, hung my camera around my neck as always, and kept it snugly in the case ready to be pulled out at a moment’s notice. To me this is the ideal camera system for doing fieldwork under extreme conditions. If you are a climber, belly tight against a rock, it doesn’t work. But for anything short of this, it frees the hands completely, and is ready instantly when the next photo op presents itself.

Smile!

So what have I learned about photography in the Transantarctic Mountains? Never take a cold camera into a warm space for fear of condensation, which will freeze when the camera goes back out into the cold. Always take about three times more batteries into the field than you expect to need, and in the old days, several more rolls of film. Low light never being a problem during the Antarctic summer, my film of choice was Kodachrome 25 (alas), which rendered snow close to its true white, unlike Ektachrome et al., which invariably developed too blue. I have always used a polarizing filter, never backpacked a tripod. To me, landscape photography is simply a matter of perception, of being ready when all the elements of a scene align. The only advice I ever give is to be sure to look into the corners of the frame before you push the shutter.

Gallery – Pressure Ridges

The terminus of the Ross Ice Shelf connects Ross Island with the Transantarctic Mountains across McMurdo Sound. North of the front of the ice shelf is the realm of seasonal ice, which on a given summer will be open water more and less farther south. Close to the ice shelf and around Cape Armitage by Scott Base, the New Zealand Station, is a stretch of seasonal ice that seldom breaks out. Sustained movement of this ice against the shoreline has produced a beautiful set of pressure ridges. A series of cylindrical folds takes up most of the shortening, but in a line parallel to the shore a shear zone has ripped the ice for a distance of at least a kilometer.

Rolling pressure ridges, some fractured along their crests, collide with Ross Island.

The Race Begins

October 19, 1911. Late news breaking. This just in. Norwegian Roald Amundsen and his party of four sledded off today, bound for the South Pole. They were driving four sleds each with a team of 13 huskies. They had laid depots out to 82° S by the end of the previous summer. As they left this morning, the men voiced confidence that they would make it. But one could perhaps detect a touch of urgency in their gait and the unspoken question: Would they beat the British?

Amundsen's base. Framheim, at the Bay of Whales. Photo from Amundsen's book, The South Pole, 1913.

Poised at Cape Evans on Ross Island, 400 miles to the west, the British expedition, led by Robert Falcon Scott, isn’t up to the starting blocks yet. Last season their furthest depot was 35 miles short of their goal of 80° S. The spring has been busy with preparations not only for the southern party, but also for geological parties working in the mountains to the west of McMurdo Sound. After all, Scott hadn’t planned it to be a race. This was foisted upon him when he reached Melbourne finding the fateful telegraph message posted from Madeira: Beg leave to inform you Fram proceeding Antarctic. Amundsen. Amundsen, with Fridtjof Nansen’s blessing, had commandeered the Fram to sail into the Arctic Sea, there to be frozen in, and to drift, perhaps even striking out to reach the North Pole. The program was set when in September, 1909, both Cook and Peary claimed to have gotten to the North Pole in the preceding year. With that prize lost, Amundsen hatched a bold, new plan, privy only to three others, Prefessor Helland-Hansen, his brother, Leon, and Lieut. Thorvald Nilsen, the commander designate of the Fram. At the last landfall, Funchal on the island of Madeira, Amundsen laid it out to his men, on to Antarctica and the South Pole, or home to warmth with no hard feelings. To a man they headed south. With all his promises and contracts broken, were Amundsen not to reach the Pole first would surely mean imprisonment upon his return. The stakes were high. Both Amundsen and Scott carried the other as a monkey on his back. As fortune would have it, the two camps met when Terra Nova, the British ship, found the Fram moored in the Bay of Whales at the eastern edge of the Ross Ice Shelf. Each party showed the other the utmost courtesy. The officers of the Terra Nova were invited to Framheim, the expedition’s quarters built several miles in from the ice edge, and Amundsen and two others were received on board the Terra Nova. The intelligence that Lieut. Campbell reported to Scott back at Cape Evans was that Amundsen headed a ground party of nine, and that they were well equipped and had more than 100 dogs.

So the race is set, Scott sixty miles farther north than Amundsen at the start, following Shackleton’s trail south from McMurdo Sound to Beardmore Glacier where the route crossed the Transantarctic Mountains along a 100-mile corridor of crevasses. Amundsen’s route was south into the unknown. Would the Transantarctic Mountains continue southeast from the mouth of Beardmore Glacier, as seemed likely, and bar their path, or would the great range of mountains rising at Cape Adare and continuing south for 1,000 miles peter out, giving an east access to the polar plateau and the final sprint to the Pole? Only time will tell.

Ascent of the Spectre

I remember the first time I saw a photos of the Organ Pipe Peaks. It was 1970, and I was a graduate student due to leave on my first expedition to Antarctica. I did not believe that any grouping of summits could be so dramatic, beautiful, and perfect. They were a fantasy of mountains rendered with bold and simple strokes, faceted grandeur in black and white. I dreamed of traveling to those peaks, bowing down before their central spire—The Spectre—and sampling a piece of the rock. The photos had been taken by a couple of geologists, Quin Blackburn, who had led a party through the area in 1934-35 and named the peaks, publishing his account in the Geographical Review (1937, v. 27, pp. 598-614,) and Rudi Katz, a New Zealander who had traversed through the area the year before and quickly published his account in the New Zealand Alpine Journal (1970, pp. 398-407.) Alas, the Organ Pipe Peaks remained beyond my reach that season.

Ten years later on my fifth Antarctic expedition, I found myself camped on Sanctuary Glacier, in the shadow of the Organ Pipe Peaks. My work that season had begun with geological mapping of the La Gorce Mountains and ended with a collecting traverse down the east side of Scott Glacier, essentially retracing Blackburn’s route. Now I was one day away from attempting an ascent of The Spectre—the splendid spire that had awed both Blackburn’s and Katz’s parties.

Being a klutz with ropes myself, I have always had someone in the party who is experienced with roped climbing in case we needed it. This time, the field assistant/mountaineer for the party was my brother Mugs, who had the year before made his first big mark in the climbing world with the first ascent of the Emperor Face on Mount Robson in British Columbia. From the beginning of the field season, Mugs and I had joked about climbing The Spectre. We figured he would do all the leading, and if necessary would winch me, the older brother, up on the rope. Now that we were camped in the shadow of The Spectre, looking up its backside, the climb was no longer a joke. It was real, sheer, and daunting. Mugs studied the fractured upper wall of the spire, and, although he couldn’t see a clear route, said “we’ll just wander around on the face and see where it leads.” I understood Mugs’s nonchalance and trusted him completely. I also trusted myself. I must admit, however, that I didn’t sleep well the night before the climb. What would it be like? Would the rough passages be vertical or overhung? Would I be in way over my head? I hadn’t had such a case of butterflies since before wrestling matches in high school.

After a big breakfast Mugs and I snowmobiled over to the foot of The Spectre. We carried a minimal rack of climbing gear: a half-dozen carabineers, several slings, and four pitons to secure the rope. The first half of the ascent was a straightforward climb up a steep (50°) snow chute to a shoulder on the right skyline, with Mugs kicking in all the footsteps and I following in his prints.

Mugs kicking steps at the start of the climb.

At the shoulder we pulled out the rope, and while I belayed, Mugs began working his way across and up the face, which in this stretch was pretty much vertical. When he reached secure spots, Mugs would set the belay for me, and I would follow up his path. There were good-sized cracks in the rock that gave plenty of handholds and places to rest, so I mostly managed to climb with no problem.

The most difficult passage of the climb—the crux—occurred at a place where there was a slight overhang. The only handholds were high above my head, but there was nowhere to place a toe if I pulled myself up. I thrashed around some as Mugs laughed and tightened the rope. But then I found a bulge on the rock out to my left side that could be grasped between my knees. From there I could reach the next handhold, and we were both past the touchiest part of the day.

After about two hundred feet of roped climbing (two pitches), we made it past the steepest stretch, and came out onto a rock face with a slope angle closer to 60° than to vertical and with lots of snow-filled cracks that made planting steps easy. Here Mugs packed the rope, and we continued upward across the face. We had started the day in full sun, climbing in shirt sleeves with our parkas packed, but as the sun circled its way to the south, we slipped into shade and the chill that it brings. Rather than take off our packs on the steep terrain, we decided not to pull out our parkas, and pushed on to the summit.

This is me freeclimbing the upper portion of The Spectre. Photo by Mugs Stump.

A small cornice of soft snow maybe eight feet high was the last barrier to the top. Mugs chopped and kicked his way through and over it, and we emerged into sunlight on the flat of the summit. In all directions splendid peaks reached for the heavens, piercing the undulating mantle of white and blue. No sound stirred the silence. We took a round of photos and then had some lunch.

You could say that we were pleased with ourselves. I can also say that we brothers never felt closer. Each of us knew that he wouldn’t be at this spot were it not for the other. I had provided the opportunity and Mugs the expertise. What I recall most was agreeing with Mugs that our parents would be more than doubly proud. We lingered a bit longer and finally descended; I rappelled most of the distance down to the shoulder, and Mugs mostly downclimbed after me, stripping the hardware from the belay points. At the shoulder, we figured a glissade down the snow chute would be the fastest way back to the base of the mountain, so we sat back on our heels, set the points of our ice axes in the snow for braking, and slid all the way down to our snowmobile. My dream a decade earlier of bowing before The Spectre had been exceeded. What a grand and memorable day in the mountains it had been! (Adapted from The Roof at the Bottom of the World.)

Gallery – Intrusive Patterns

When liquid magma intrudes solid rock, it often produces interesting patterns. When more than one episode of intrusion occurs in an area, the results can be highly complex. This week’s gallery highlights several localities where multiple intrusions have left their marks.

Adélie Penguins

20 miles north of McMurdo station, at Cape Royds, is the southernmost adélie penguin rookery on Earth. At the start of most of my seasons, I have done a shakedown run for the snowmobiles out to the rookery. Already by early November the penguins have walked in many miles from the ice front and have staked out their space in the rookery, built a nest of stone pebbles and laid an egg, or rarely two. Where the penguins reside is off limits to everyone except for the odd biologist that might be doing research there. However, it is possible to get quite close and still be outside the boundary. By late November or early December the chicks are hatched and the parents become a tag team walking to and from the ice edge to catch food to feed the chick. As the summer progresses the sea ice breaks up and travel across it ceases. Only once did I visit the rookery in mid January, flown there by helicopter. By then the chicks had grown to the size of their parents, but still had not lost their gray down. What follows are several of my favorite adélie penguin shots.

Proud parent.

Doubly proud parent, or did I detect a note of concern?

Adelies have the ability to shoot poop out from the nest without ever leaving the egg.

Hang Time

For decades USAP personnel have not worked Sundays in McMurdo. It gives a chance for recreation or a time to sleep off a Saturday-night booze up. Remote helicopter camps follow the same routine. However, in a remote field camp, beyond those company rules, we work every day that the weather permits. Field time is too precious not to. One must count on days of bad weather, sitting out storms, waiting for the weather to break, hanging. Antarctic camping is no bivouac. We are relatively comfortable with a cook tent where you can sit, be warm, and socialize, and sleeping tents where we can rack out and be alone. How well you hang probably largely comes down to personality, but there are lots of variables that may come into play. When you are a field party of four, crammed together in intimate quarters over a period of weeks and sometimes months, it is critical that personalities do not clash. A good sense of humor, no whining or complaining, an eagerness to pull one’s weight, seeing what needs done and doing it, these are characteristics that I think are important in a field mate. I am happy to say that in all the years, I have made only one mistake in choosing my field teams.

Headed to the sleep tent for some rack time.

I wouldn’t say that being laid back is a necessary trait for hanging in a tent, though it helps. Someone who is animated or boisterous can be very entertaining during long stretches. But I hasten to add that personality ticks can get on your nerves in such close quarters. One of my mates one season had this annoying habit of sticking his tongue out and lightly touching its tip to the left side of his mustache. By the end of the season I was saying to myself, if you do that one more time I’m going to punch you on the chin and have you bite the damn thing off. Another season, there was a particular giggle that still gives me shivers when I think of it. The pastime of choice for most is reading. A good book can burn away hours when you’re sitting on a rock box, munching on munchies. It is hard to read for long in the sleeping tent without getting cold. When the sun is out full and there is no wind, a sleeping tent can be warm enough not to use a sleeping bag, but if it is storming outside you get cold quick, and a small one-burner stove may be necessary if you want to read for any length of time. I read some in the field, but prefer to occupy my time with other sorts of diversions. Everyone likes to eat, and I like to cook, so that can fill hours for me during a storm. Baking is something that we never do on a normal work day. Coleman stoves (good old green, two-burner, white-gas standards) have an accessory for baking, which is essentially a collapsible metal box with an oven door and a thermometer that you set on the stove. Give me an hour and I will serve up a beautifully browned yellow cake, still warm, smothered in frozen strawberries. Cut that into four and it disappears in one long breath. So let’s do it again. Pancakes on the cast iron skillet can go on for hours during a storm. I also usually take some sort of handicraft. Needlework is very absorbing when I’m sitting on a rock box. One season it was embroidering a shirt, other times sewing pouches out of canvas from the tent repair kit or from leather scraps that I’d taken along. I spent one, whole season whittling on a piece of walnut wood with an exacto knife. Mugs liked to play Battleship, so I heard a lot of “Spee-lash!” during the three seasons that we worked together. Of all of the ways that there are to pass time, the best by far is to be unconscious. How long can you hang in sleep? Those who can do it for lengthy periods have a real gift for sustained storms. The longest storm I have experienced was for eight days in December 1977, camped on a broad névé (snowfield) to the north of Leverett Glacier. There was probably some precipitation at the beginning, but most of the time we were in howling, blowing snow. The tents were laid out perpendicular to the wind direction with maybe 30-foot spacing between. For the first several days we couldn’t see the adjacent tents. Very quickly a large drift built itself between each of the tents. They were about six feet high and required crawling over when we went to and from the cook tent. My recollection of that stretch is one of a deepening stupor, stuffing myself with food, throwing some stitches on the embroidery, and lying in the rack for hours either in real sleep, or in a state just this side of it, black beanie pulled over my eyes, prone, thought shut down, TM meeting hibernation. When the storm finally blew itself out, it took us a full day to dig the camp out. The drifts between our tents extended at least 100 yards down wind. One snowmobile carelessly parked was totally buried in a drift. The day after we dug out, another storm came down and in a final “Up yours!” packed everything with snow all over again. And so it goes. (I am sure that there are some of you out there who can top eight days stuck in a tent. Why not weigh in?)

Sweet dreams.

Gallery – Pack Ice

Every winter the Southern Ocean surrounding Antarctica freezes over with seasonal ice and every summer this ice breaks up, drifts northward, and melts. Pack ice is the name given to the broken pieces of seasonal ice, distinct from the much-thicker ice bergs, which form by the calving of ice from glacier tongues or ice shelves. Depending on storms and currents, the ice pack (sometimes called simple the pack) may be loose or tight, the individual ice floes large or small, sharp-edged or blunted. Sometimes several generations of break-up and refreezing are visible. This week’s Gallery was shot en route to and from McMurdo Station.

Topo Base Maps

This week I want to talk about what has gone into the creation of the maps that are illustrated in The Roof at the Bottom of the World. The base maps were produced by the U. S. Geological Survey after the International Geophysical Year (1957-1958), in a rush of activity that charted the entire length of the Transantarctic Mountains at a scale of 1:250,000. Combining aerial photography with ground control, the first printed quadrangles were published in 1959. Topographic engineers who created the initial ground control accompanied overland traverses or utilized helicopter support in coastal areas. Over the next five years, six to eight new maps were added annually to the portfolio of the Transantarctic Mountains. In 1964, the Topographic Division produced an astonishing twenty-four 1:250,000 sheets, covering all the bedrock outcrops of the Transantarctic Mountains, except for five quadrangles, which were published the following year. This bonanza followed a remarkable pair of seasons (1961-1962 and 1962-1963), during which a crew of topographers supported by a pair of Army helicopters surveyed the entire 1,500-mile length of the Transantarctic Mountains. In the book, I tell the story of these campaigns for the first time. During the period of peak productivity, the personnel at the Topographic Division assigned to the Antarctic quadrangles grew to about 180 participants. The teams split the tasks that included careful measurement and marking of peaks on aerial photos, linking summits to ground control, transferring points to a scribe sheet, measuring and drafting in contour lines, distinguishing ice from rock, adding color, outlining crevasse fields and moraines, air-brushing shaded relief, and inserting geographic names--all the while checking and rechecking everything for accuracy. The contour interval (the elevation difference between lines on the map) of these maps is 200 meters. This interval is very coarse when it comes to reckoning on the ground, but cartographers added air-brushed, shaded relief depicting the landscape to a detail that far surpasses that which can be read from the contour lines alone. With burnt siena bedrock, pale blue ice, and the sun perpetually shining in a northwestern sky, the air-brush rendering has provided a magnificent base map for tracing of the routes of the explorers, showing precisely where they traveled into the mountains, through crevasse fields, around ridges, over passes, up outlet glaciers, and onto the polar plateau. In the 1990’s the USGS scanned all of the 1:250,000 quadrangles into digital format and made them available to the public.

Franklin Island Quadrangle, 1:250,000, U. S. Geological Survey. Note that only the southwestern corner of the quadrangle was used.

For the figures in the book I merged those quadrangles that covered the area that I wanted to show. The USGS provides digital copies of the quads with both the margins intact and with them stripped away so that one can collage the quads seamlessly. But even though the merger is quite exact, the colors of the original, printed maps varied in some cases, so this shows up in the scans.

Once the collage was complete, I cropped the map to the size that I wanted. The next step was to Photoshop out all of the geographical names, producing a clean base upon which to work.

Next I re-inserted names for those places mentioned in the book.

Finally, I drew in the traverse routes of the explorers using Adobe Illustrator. In some cases I composed the routes by a careful reading of the original accounts, but in others I was able to follow maps made by the explorers that showed the routes they took; for example, the map that follows by Griffith Taylor.

Gallery – Zipper Ice

Straddling the boundary between northern and southern Victoria Land, Terra Nova Bay is home to open water during a longer period of the year than anywhere else along the Victoria Land coast. This is due to persistent katabatic winds (cold, gravity-driven winds) that pour down David Glacier and open the bay. In November of 1980, I observed an unusual phenomenon in this area. A thin sheet of ice had recently frozen over the open water. (I don’t know how thick, since we were at about 30,000 feet, but probably only a foot or two at most.) Some sort of pressure (currents or wind?) pushed the ice to the point of fracturing, but instead of a clean line with one side of the ice overriding the other, in this case each side took turns at being the one that rode over the other. I have heard this called “zipper ice,” though a quick trip to Google produced no hits for this feature. If you have a reference to zipper ice or have seen it let me know.
