Sounds like the right name for it - Gibraltar chute. It is next to the Gib ledges. Timing was good - no icefall when we were passing. We heard icefall early morning, on the way up.

We parked in area west of the gate, as labeled "park here" by NH-S in this thread We looked for signs in that area and did not find any. That area starts out wide enough to park cars perpen...

Thanks for sharing. I have not heard of this. There are so much history in the region! I like how this story is tied to the great forces of nature, with lesson for skiers like us here.
