In early season while still covered in snow, that route is a fun climb, though a bit steep near the top. It is somewhat less steep than the tops of Army, New Army, and "Navy" passes, though. I don't recall there being any significant difficulty with the route other than the rather steep exit. I haven't tried it when dry, but the chute on the opposite side of the drainage visible in your "Looking down scree field" picture is not as bad as it looks when dry, and makes a nice variation as well.
