Nipple Butte is a peak in the Malheur National Forest.
"Take Hwy 26 East to Mt. Vernon. Turn left on 395 and head north for 11 miles. Take a right on road 3940. Stay on this smooth gravel road for about 7 miles. You'll come to a fork.... Take a right over the cattle guard where you'll see a road sign #3947. Travel this road for about 3/4 of a mile. Look for the unmarked trailhead on your right. It looks like an old road with logs and trees across to deter motor vehicles. Walk a half-mile on the road, then scramble up to the left and to the ridgeline. “
