I was chatting with the operator/outfitter of Temperance Creek, Brice Barnes, a few days ago and he informed me that it is open for business. They have a full time caretaker who will provide breakfast if you call in advance. The Forest Service has asked them to limit landings to planes using the services of the Lodge. They also have cabins for rent. It is a pretty cool spot on the Snake with a fairly benign approach and strip as far as Snake River canyon strips go.
