Registration


Join waitlist


Join MAA members for a winter ascent of the "lightning-rod of the Cascades", Mt. Thielsen. With a needle-like summit and readily accessible just north of Crater Lake in Oregon, this peak is a fun winter climb. Attendees should be comfortable with winter camping, serious exposure and be confident with self-arrest and climbing steep snow. Loaner gear may be available to paid members. Elements of the SNOW 1-4 and MTN 2 training courses will be a part of this climb. Maximum of 8, recommended for those with good fitness and some mileage in the mountains.

SCREENED EVENT: Please join the waitlist. Attendees will be selected based on skill proficiency and experience shown on MAA profile. Those registered will be notified.



DETAILS
  • WHERE: Mt. Thielsen, central OR, north of Crater Lake, Hwy 138 just east of Diamond Lake.  
  • ROUTE: Winter ascent of the West Ridge (approx. 3 miles, moderate snow) or the North Ridge and to the summit pinnacle (Class 4, snow over volcanic rock) and back. Will bring ropes and some protection for safety. 
  • EVENT LEADER: Darren Shutt, (916) 872-3399, darren@mountainascent.org
  • GROUP SIZE: Minimum 2, Maximum 10
  • TRAINING AND CLIMBING SKILLS REQUIREMENTS: MTN 2 Winter Mountaineering and SNOW 1-4 training courses material will naturally be addressed on this event. In order to be best prepared to climb safely and effectively, participants should be able to hike 3 miles in deep snow, climb about 3,000 feet in snow with a 30 pound pack, climb loose, snow covered rock on an exposed ridge in a rope team, and be comfortable traversing steep snow without protection. 
  • PERSONAL GEAR: Members are encouraged to use your own equipment. If you're missing something, loaner gear may be available. Please let the event leader know if you need something. 
  • FITNESS AND DIFFICULTY LEVEL: Moderate, but conditions may push the needle to "challenging". The ascent will probably take about 4 hours of constant effort, the descent about 3 hours. Be prepared for winds, cold temperatures and a heavy workload - it's a winter ascent.
  • MEDICAL: If you have any medical conditions pertinent to your participation on this event, please inform the event leaders after you’ve been accepted on the team.
  • GETTING THERE: Check highway cams at www.tripcheck.org. Meet at 8:00 am at the Mt. Thielsen Sno-Park trail on Hwy 138, west of Diamond Lake, OR. You will need a sno-park pass, which must be arranged before hand. CA sno-park permits are honored in OR. There is a restroom there. 

ITINERARY

Prior - Selected team will communicate and coordinate details over email and phone.

Friday, Feb. 3rd - Meet at 8:00 am at the Thielsen Sno-Park on Hwy 138. Sno-park pass is required to park there. We'll meet, sort gear and hit the trail by 10:00 am. Snowshoe / ski about 3 miles where we'll dig in our tents to establish basecamp. We'll review self-arrest and snow climbing technique, and enjoy a nice warm evening meal and an early bedtime.

Saturday, Feb. 4th - Starting around dawn, we'll gear up and begin the ascent to the summit right from camp. Preferred route is the North Ridge, but we can also ascend the non-technical West Ridge. Either way, we aim to summit by noon and descend the West Ridge back to camp. We'll break down camp in the afternoon and trek back to the trailhead, arriving around 4 pm.
