Big Horn is the largest of the "horn" rock formations leading W from Mount Curtis Gilbert. This area is in the Goat Rocks area in southern WA, between Mts. Adams and Rainier. Other peaks on that ridge line are Little Horn, Black Thumb and Goat Citadel. The climb itself involves ascending a chimney system on the South face (many ledges, class 3). The final summit pitch according to Becky is a "difficult" 10-ft. vertical crack. This area is in the Goat Rocks Wilderness Area, and it's called that for a reason. Might want to bring binoculars for mountain goat watching.
