I found/visited Summitt-Snapp Cemetery in 2010. It is on private property (a cattle ranch in the Headquarters area), which required permission to cross the property. It is on top of a small mountain/large hill and was protected by some large trees to some extent, but the stones were almost all displaced, broken, knocked over, and mostly unreadable. We found a couple of Snapp stones which my husband photographed.
I am a descendant of George Fryman and Margaret Snapp, through their son Elisha who married Ellen/Eleanor Worrell/Whirl.
