Mount Church has never been officially named or measured, but its summit is slightly above 12,200 feet and it is unofficially named after former Idaho senator Frank Church. The climb to the top is quite intense, but it offers stunning views of the surrounding Lost River Range mountains. The easiest route up the mountain involves climbing Donaldson Ridge to the southeast; from here, it's possible to cross along the ridgeline to the peak of Mount Church. There are no fees or required permits for the area, and limited camping is available at the base of the mountain.
