Climbing Experience:

Climbing since 1976, I have summited big mountains, hauled heavy bags up big walls, spent tent time on long expeditions, and played in the sun on countless short sport routes at a wide variety of ratings. These days, I am comfortable leading two tool water ice to about WI5 and free (trad/rad) rock routes to about 5.10b, a respectable recreational standard of performance. I draw the nailing line at A3+!!! While exploration geology usually does not require mountaineering skills per se, an ability to move confidently in steep country can be very important. Also, as exploration moves more and more to hostile, diffcult terain, the attitudes and skills gained during wilderness travel become increasingly important. Climbers tend to be skilled at surviving hardship, and for some reason seem to actually thrive on it. If you are contemplating a field season in remote country, feel free to send me an email. I ALWAYS answer my email, although if I am traveling it may take some time!

Antarctic mountaineering during scientific expeditions:
  • Mt. Browning (1988): Non-technical ascent during two month long geophysical camping expedition in north Victoria Land.
  • Brimstone Peak (1990): Semi-technical ascent during two month long geophysical camping expedition in north Victoria Land.
  • Mt. Adam (1991-1992): Second ascent, ever, of 4010 meter peak in North Victoria Land, while collecting rock samples for geologic age dating. Ascent required four weeks and over 700 kilometers of skidoo and sledge travel to and from the put-in site over wide valley glaciers. Lots of experience gained in cold-weather survival, expeditioneering, polar travel, and mountain navigation.
  • Peak 2090 descent (1992-1993): Technical descent, after helicopter emplacement, requiring 16 rappels, some hanging belays, and serious glacier travel under white out conditions, while collecting rocks for geologic age dating. 31 hour epic.
  • Mt Goodwin, Pirrit Hills (1992-1993)
  • Landmark Peak, East Ridge; Mt. Twiss, East Ridge; Patrick's Peak, East Ridge; Mt. Virginia, South Ridge (Heritage Range, 1992-1993): Simple climbs but serious, deep-field expeditions, collecting rocks for geologic age dating. Lots of sledge and snowmobile travel, crevasse crossings, and navigation
  • Mt. Waeshe and Mt. Sidley, Executive Committee Range, Marie Byrd Land (1994- 1995): no summit climbs, but major snowmobile traverses to ~3000m in alpine areas.

Guiding Experience:

Mt. Baker:

  • Coleman Deming Glacier route: 5 ascents (1985- 1987).
