A day in the field

So, what have we actually been doing in the field for the last 2 months? Each workday begins by starting up a snowmobile with a broken choke switch, which requires two pairs of hands, a set of pliers, and some love (i.e. Graham hauling violently on manual-ignition chord). Once parked near our destination ridge or cliffs, we dismount and set out for our farthest destination on foot and work back to the machines. “Empty” backpacks (i.e. without samples, but laden with sledge hammers, chisels, first aid kit, water, spare cloths, crampons, ice axe, etc.) are never lightweight, but the crampons are invariably necessary to climb off the glacier or up a hardened snow slope. 
When it comes to approaching fresh outcrops of rock, each geologist has there own style; Sophie, for example, crouches to look for minerals in her magnifying hand lens, whereas Graham takes measurements with his Brunton compass. I generally prefer the more direct approach of obliterating the nearest piece of rock with a six-pound sledgehammer. After heated debate of the geologic characteristics of the rocks—orthognessic? poikioblastic? porphyroblastic? pseudomorphic?—we scribble in yellow notebooks. The detail and thoroughness (and accuracy?) of my notes scale with temperature (1+ page at 25 F, 3+ lines at 5 F, and 1 line at -10 F), but I reason that writing with frozen fingers will yield illegible results anyway… Before stumbling to the next cliff, we chisel away and pack grapefruit-sized samples for extracting zircon, monazite, titanite, or garnet. Each of these lucky samples will have a scenic journey to sunny California onboard a freighter before being bombarded with electron beams and blasted with lasers.
