Mountaineering with the Obsidians
The Obsidians sponsor climbs of most major peaks in the Oregon Cascades
during each climbing season. Climbs are scheduled for Washington and
California peaks less often, but there are several such climbs on the schedule every year.
Climbs vary in difficulty from ‘walk-ups’ to technical rock and snow climbs.
Even the easier climbs are still strenuous experiences, often with ascents
of several thousand feet on summit day. Persons signing up for climbs must be in good
physical condition and be prepared to carry group gear such as ropes or pickets in addition
to their own personal climbing and camping gear. Most climbs require two days or longer.
The Obsidians is not a guide service. Participants are expected to have at
least basic mountaineering skills, and you may be asked to describe your climbing experience
before being allowed on some climbs. Participation in most climbs is limited to those who
have completed the Basic Mountaineering class (either the one offered by the Obsidians, or
an equivalent course offered by another organization).
The party size on climbs is also limited. Wilderness area restrictions limit
the party size to no more than twelve, and many leaders choose to limit the numbers to less
than twelve, depending on the route difficulty and other factors.
To sign up for a climb, you must sign up
through the on-line sign-up process (access through this link).
Climbs are generally posted about a month before their scheduled dates.
The current climbing chairperson is Brian Hamilton.

Climb—Mt. Hood—Saturday–Sunday, May 25–26, 2013
Leader: Danneille Harris
Plan is to take a single 4 person rope team with just folks who are well prepared as this will be my 1st lead of this route (standard South side/Old Chute, I have climbed this route just not lead it). 12-12:30 am start from Timberline. Be prepared for icy conditions, cold, wind, rain, and hot weather. If you plan to arrive early to get sleep at the parking lot before the climb, bring sleeping bag & pad, and ear plugs.
Climb—South Sister - Climb/Ski—Saturday, June 1, 2013
Leader: Sue Sullivan
The actual date of this trip may change depending on the opening of the Cascade Lakes Highway and access to the south side of South Sister. The plan is to carry skis or skin up and climb South Sister from the Devils Lake trailhead, then ski back to the trailhead. In good conditions this is one of the nicest ski mountaineering experiences in Oregon. You must be an experienced backcountry skier to participate.
