Castle-First Mother Ridge Transit
The title sums it up. I attempted a transit of the ridge between Castle Peak and First Mother Mountain, but ended up dropping down to the Knapsack Pass trail at the end when confronted by rocky outcroppings. But that's just me, I got it in my mind to "escape". Others may well stay high, skirting the outcroppings on the right to connect the two peaks without the short detour to Knapsack Pass.
