Trip Summary | |||
March 18, 2024Winter Trip up Even Thomas Creek, well known for several Ice Climbs. "Green Monster" is the most popular and most scenic, but it is not so easy to get to. Problem is narrowing of the Canyon by Even Thomas Creek Waterfall; continuing up the creek is not feasible anymore and one must use bypass on left (north) side. This bypass is not trivial and would be quite dangerous without chains. Spikes are a must. Upper canyon is quite scenic with lots of pools and snow bridges (that will also become dangerous as weather warms up).
From Evan Thomas parking follow Fireroad for ~20min, then drop right to Creek level (Waypoint "1, 6 - Creek Junction" on GPS Track), then head upstream. Trail up the creek is usually well broken in winter and going is easy. Depending on timing there might be some snow bridges or open water to jump across. 45min or so brings you to Upper Canyon where further progress is not practical - see Gallery. Crux is narrow ledge where slip is not an option; use chain and go slow. Turn back if unsure in your abilities as return is the same way. After descending back to creek level going becomes easy and quite scenic. Green Monster is 15-20min further up the Canyon. There are several minor Ice Falls along the way, but you will know you are at the Monster when you see it. On weekends this spot is usually quite busy with Ice Climbers and Hikers alike.
After clearing the Crux on return, loop return via Summer trail is option. Unmarked connector will be on north (right, coming back) side few minutes past Canyon mouth - Waypoint "2, 4 - Canyon". If trail is broken this longer return will provide variety. It will take ~20min from Creek level to Evan Thomas Fireroad where you turn left (Waypoint "5 - Fireroad"). On my trip there was some fresh deadfall but it didn't present problems.
