According to Colonel Harold B. Wharfield, who interviewed some of the participants in the Bear Valley fight and published his story in the book Tenth Cavalry and Border Fights, wrote that the camp was located in a dangerous "uninhabited region" where "unconfirmed mysterious disappearances" often occurred and people were advised to travel in groups. The camp was built next to an old homestead and a high ridge to the east, which provided an excellent view of the surrounding flatlands. After the January 1918 New Years Day celebration, Captain Frederick H.L. "Blondy" Ryder and his Troop E, 10th Cavalry, were ordered to occupy the Bear Valley camp for border patrol duty. A signalman was posted on top of the ridge who could communicate via hand signals with one of the sentries placed around the camp's perimeter. The rest of the soldiers patrolled the trails leading in and out of the valley, watching for people wandering through the desert.

The Book, Tenth Cavalry and Border Fights can be found in your local lending library via inter-library loan. I am now kinda interested in reading this.
