Elevation: 6,279 ft
This summit is not in the book.
Marks Butte is named on the Grandmother Mountain USGS Quad. The summit is just west of Freezeout Saddle and 1.5 miles south, southeast of Grandmother Mountain. When I lived in Moscow, this was a popular crosscountry ski destination but not a hiking destination because of the nearby roadway. FS-301 (B)(2)
