Most Mazamas climbs are open to anyone who applies. Some leaders prefer to restrict their climbs in some manner. These “restriction codes” are listed below:
- (+) Indicates there is a pack-in to base camp (not car-to car in one day)
- (R) Relaxed Pace
- (E) Exploratory - Indicates the leader has not previously climbed this route
- (F) Family climb - kid friendly at a moderate pace
- (H) Hike to the Summit - nonmembers given preference on a glaciated peak climb
- (L) Linked Climbs - climbers must apply for two or more climbs from the same base camp on the same trip.
- (A) Adjacent Climbs - climbers may apply for two or more climbs located in a similar area.
- (S) Ski Mountaineering climb - backcountry ski or snowboard gear required
- (Y) 20s&30s Mazamas - for those young or young at heart.
Mazamas climbs are graded to indicate approximate experience and/or ability levels required. You can think of the grades as approximately: A/B = beginner, B/C = intermediate, C/D = intermediate/advanced, and D/E = advanced
The grades are:
- A - May require off-trail hiking, ice axe and crampon use on moderately steep slopes, and self-arrest. (examples: Mt. St. Helens, Mt Adams)
- B - Same as “A” level, as well as glacier travel, and roped climbing. (examples: Mt. Hood South Side, Middle Sister)
- C - Same as “B” level, as well as crevasse rescue skills, belaying, rappelling, and low 5th class rock climbing. (examples: DC and Emmons on Mt. Rainier, Mt Washington in Oregon)
- D - Same as “C” level except on steep snow slopes, glacier travel and crevasse rescue, self-arrest, belaying, rappelling and 5th class rock climbing. (examples: West Ridge of Mt. Stuart, Mt Hood, Sandy Glacier Headwall)
- E -Multi-pitch technical routes same as “D”, with high degree of self-sufficiency and proficiency using technical skills under high exposure, sharing high angle leads, setting protection and anchors. (examples: North ridge of Mt. Stuart, Beckey Route, Liberty Bell)
