Sisters, OR - Broken Top Mountain

South Sister & Green Lakes from Broken Top Ridge

Summer was upon us and I had a list of mountains that wasn't getting any shorter. With the majority of Washington's volcanoes already climbed and never having been on any of the Oregon volcanoes I thought we'd go adventure in the state to the south. After ringing Chris Pope and getting him to sign up after years on the couch - well not really, lets just say he had an extended house project - we hatched a plan, packed and were off. First stop was to climb Mount Hood as a warm up but as we approached Government Camp we talked about how it would be a better winter ascent on skis and so we continued on into the night and headed south for Sisters and the three Sisters mountains. The plan was to head up into the Green Lakes area and knock off South Sister and Broken Top.

Unpacking and packing at the trail head

The weather was cool but sunny and there weren't many cars at the trail head so we were in hopes that it would be a quiet time up in the wilderness. The trail was easily followed and after about 5 miles or so we found ourselves up at Green Lake. On the way in we passed some massive pumice fields which were remnants of active volcanic flows of the SE side of South Sister Mtn. It was fun to find pumice with such a low density that the rock actually floated when we tossed them in the lake - yup floating rock!

After refueling at the lake and taking in the scenery the weather began to threaten with distant thunder and small squalls moving through the region. Figuring we could come down from the ridge should it get worse we decided to head up and see if we could summit Broken Top Mtn. The tread gets thin as it leaves the lake but we eventually found our way up to the long NW Ridge route that leads up to the summit.

The ridge finally yielded to some snow and eventually to the crappy rock up high that everyone writes about. It becomes 4th and low 5th class but because we didn't have a rope and the rock was rather loose Gaby and Chris decided to stay below. Gaby tried at one point to ascend a section but after pulling out a large cooler sized block she didn't feel it was worth the effort. I found a fairly stable passage and decided to head on to the summit being careful that I was on my own and without any additional protection. After the passage through the basalt band there were a series of ledges and catwalks which meandered up to the summit ridge.

Of course the weather clears after we descend!
