 In 1877, just prior to the discovery that led to the founding of Tombstone, Schieffelin established a "permanent camp" at Brunckow's Cabin to be used as a base for exploring.With his brother, Al, and a fellow prospector named Richard Gird, Schieffelin searched the area for weeks, constantly on the lookout for hostile Apaches, but his stay was uneventful.There were, however, "several fresh graves" at Brunckow's Cabin that served as "mute testimony to recent Apache raids."
