Thanks for your post!
We were aware that we were going into a special place. Will, the boat-driver, even told us that native artifacts have been found in the area we were going. Our intent was as little impact as possible.
I would like to take this opportunity to clarify a few things, impact-wise.
1. We used the machete exactly twice: once to battle through devils club on a steep slope to escape an impassable part of the Perry Creek drainage, and second, a single branch to the fire to honor our route name.
2. The two fires we made were right on the creek, and will disappear at next snowmelt. That goes for our 2nd day camp as well. Our basecamp was on a flat rock in the talus field, requiring minimal clearing of stones.
3. We took all of our garbage out with us, except (as pointed out) the webbing and gear required to get us off the mountain. We also "cleaned" a carabiner from the 1958 party's ascent. We used no flagging on the approach or descent.
I feel certain negative assumptions have been made. I hope this clarifies them somewhat.
Sorry about dropping the permit ball.
