At an elevation of 4464 feet, Whetstone Butte affords great views of two major drainages on the Siskiyou National Forest. To find Whetstone Butte, follow highway 199 south out of Grants Pass to the junction with Forest Service road 2401 about 3 miles south of Selma, Oregon. Then turn onto 2401 and follow it for about a dozen miles toward the Kalmiopsis Wilderness and Babyfoot Lake. When you come to the junction with Forest Service Road 869 take it toward Onion Camp. In less than a mile turn onto Forest Service Road 873 and follow it a few hundred yards till it skirts trail 1124.
Whetstone Butte is about a mile north on the trail.
A short cross-country scramble hike of 100 yards is necessary to get to the summit of Whetstone Butte. The view and feelings of solitude that go with the view are well worth the short hike in my biased opinion. I have never encountered another hiker there. I like to continue hiking on trail 2401 for another 3 miles and hit road 087 where it crosses Chetco Pass. It's possible to have a vehicle pick you up at that point.
