RECREATIONAL PURSUITS

When I get away from Missoula, I like to go alpine climbing, back country skiing, and the like. Among rock climbing, ice climbing, mountaineering, and just rambling around, long routes on remote/oddball peaks seem to provide the most lasting memories. The Canadian Rockies and B.C. Interior Ranges (check out Bivouac.com) are nearby, they've soaked up a few seasons and recently we've roamed around the BC Coast Range a little. A pleasant night-drive will get you from Missoula to the Wind Rivers, Cascades, Tetons, or Sawtooths if the weather in Canada is dicey. Steering among wind-driven flakes pushes the espresso buzz right into the pre-buzz for ice climbs or telemark trips. Usually we've booked the Hotel Toyota, but I've spent seasons climbing and exploring in the Alps, Great Britain, Peru, Bolivia, Antarctica, Australia, Baffin Island and New Zealand as well. And, of course, it's all really research - first hand observation of orogenic belts to better understand the evolution of crustal structures. I intended to get some climbing in while I taught Geophysics at the University of Papua New Guinea but I got bogged down with the scuba diving. The Australian climbing trip resulted in two pitches and more underwater time than diving in papua New Guinea - so much for surfing. I'm just not that big on becoming one with the sediment. Recently I managed some more diving, this time on WWII wrecks off Busuanga Island, after completing a little environmental geophysics project in the Philippines. The following summer it took a few weeks on the Tatshenshini-Alsec Rivers, bagging first ascents in the Fairweather Ranges, to cool off from the tropics. Closer to home there's good mountain biking, rock climbing, backcountry and lift-service skiing, kayaking, and lots of great cyclocross routes for human-powered local exploration. Right off campus there's Mount Sentinel, 1,958 feet (I think the record is ~20:04), of cardiac output ready to remind you of the pleasures in belaying. Another hobby led to some energy saving results from basement insulation.

Cordilleran summits I've visited:
