Squaw Butte South is the second highest point on the Squaw Butte massif. Most people incorrectly believe that the summit of Squaw Butte is at a fire lookout located at the southern end of Squaw Butte South. The lookout is not the highest point of either Squaw Butte South or Squaw Butte. The highest point on Squaw Butte South is 5,894 feet. The lookout’s elevation is 5,874 feet. In between these two points are two other points of almost equal altitude. The actual high point of Squaw Butte is only 2 feet higher than Squaw Butte South. Thus, if you want to claim an ascent of Squaw Butte South, you have to go to the north end of the ridge containing the lookout.
