Thinking about doing Uintas instead of Wind Rivers; if I do, this is my proposed route.
Route
Trailhead
Leave Trail (No official trail over the pass south of Upper Red Castle Lake, but rumors of a "use trail" are frequent, and even without it, the route is reportedly fairly easy.)
Rejoin trail
Leave Trail here (Relatively flat and open; should be easy to route-find to Crater Lake, by reports. Also, can follow the creek.)
Rejoin trail
Leave Trail here (Explore Tokewanna cirque and camp there.)
