For those needing a stop for, fuel, food, or overnight lodging I would like to put a plug in for Grangeville, ID http://www.airnav.com/airport/S80
It is just a hop from Elk City and the Church Wilderness.
If you need a place to stay I can strongly recommend the Super 8:
Super 8
801 SW 1st Street, Grangeville, Idaho 83530
For Reservations and Info Call 208-983-1002
If you cannot get one of the Idaho courtesy cars ( $5/day $0.33/mile) at the airport the folks at the hotel will pick you up and bring you back.
Airport managers live on the airport.
Fuel this past weekend was $4.09/gal.
