The trail starts at the end of a dirt road just past Snoqualmie Pass. It immediately heads up steeply, and never lets up. About half way up we turned off the trail in order to avoid the deep snowpack, and the trail got even steeper.
It was interesting to see the steep fins or dikes. These appear to be volcanic formations, more resistant to erosion than the surrounding rock, that make steep walls on the canyon walls. We reached a radio tower, where we ate lunch and turned around.
