Any route or boulder problem that starts out of or near an occupied campsite may not be done without first obtaining the campsite occupant's permission.
This is the easiest route that goes up the full height of Intersection Rock. It is a reasonable way to downclimb from the top. Move up and left across a slab, go up a chute, and move left across easy face climbing to a belay. Different guidebooks illustrate different routes above here. The most obvious way is to climb (4th class) along the left side of a huge, steep flake, then traverse 20 or 30 feet right to a short final section
Location
It starts about 50 feet right of The Waterchute, on the southeast side of the rock.
I did this climb and thought it was a fun adventure.
I took a different route than said here. 1st pitch was the same, but then I tunneled right(off belay) until I reached another short pitch of climbing. This section was dirty and grovelly and harder than 5.3 (IMHO but not worse than 5.6). Then some more gophering through passageways to a quick move to the top. I roped up for the last move just because of the fall potential. It was easy but grunty.
The way I took was more or a belly crawl/back at the playground good time than this route listed here, but fun nonetheless.
We did this in 5 pitches! (long story) We also tunneled right from the end of the first (our second) pitch. Then up a really nice hand crack that was fun jamming. Then easy terrain to a short chimney to the top. The move to get in the chimney was fun and easy to protect.
