Trip report
Feb 15, 2017 — It's hard to rate the difficulty of this guy because the hike is really just a series of easy Class 5 moves on obstacles with Class 3 consequence. It's not particularly strenous, but does use lots of upper body to get over dryfalls. To give an example, there were at least two obstacles we climbed that had anchors for rappelling at the top.
The higlight of this hike was when we wandered up a side canyon that had no footprints leading to a particularly difficult dryfall. After continuing up this canyon that had absolutely no signs of human activity, we got to an unpassable dryfall. As if by luck, we looked to our right and were greeted by a beautiful natural arch that beckoned for a Class 2 scramble to get up to it. We went through it and continued down a gully to make a mini loop back into the main Grotto Canyon.
On the way back, we located another side canyon on the east side of Grotto Canyon that led to an impassable dryfall, but had more fun obstacles and rock features.
