Be Still My Beating Heart
Not too hard in this canyon, which, though somewhat pretty, is not too terribly exciting. Just when it starts to get going, the technical part ends. "Not much meat on this bone," was the consensus of our party.
Still, it offers easy access to the top of the North Fork of Robbers Roost Canyon, and this write-up includes "The Crack" exit back up to the civilized world. It makes for a fine day visiting some remote and seldom-visited deep canyons, while not taxing your technical skills.
On the other hand, another party found deep, muddy potholes that required swimming and cleverness to exit. The canyons are constantly changing - be aware, have fun, but be safe.
