"Set out with the intention of climbing Echo and Observation Rocks, but decided I didn't want to do the loose rock on my own. Called an audible to check out Hessong Rock and then completed the loop." — TynanRammGranberg • Sep 15, 2023

The map seemed to indicate I should climb up a small waterfall, but upon reversing my track, I found a short westward section that crossed a small stream then immediately turned south.
Followed the boot path to the Fay ridge. Thought about climbing the rocks at the west end of the ridge, where the boot path arrives, but it was too slippery. In general, I was soaked already from squeezing past trees, and I put my rain pants and rain jacket on. This way, at least I was wet and warm instead of wet and cold.
Followed the boot path towards Fay Peak. Attempted to scramble it from the west side, but with the slippery rocks, that wasn't all that easy. I made it on the northwestern flank, but then discovered that it would have been a walk-up from the east (not too surprising, looking at the map).
Further followed a boot path along the ridge past the middle rocks, which I climbed, to East Fay Peak. It looks like it would be..." — mathiasricken • Sep 21, 2019
