These are the two crux towers below the summit of Ervin Peak. It seems possible to avoid the first one on the left by descedning, but the second would require too much elevation loss to circumvent. Hint: There is a ledge to the right side that keeps the difficulty class 3.

There was a lot of loose rock on this section of ridge, I cleaned a few of the nastier blocks off but depending on your route you may find others. Test each block carefully!
