Where in the Owyhee's did the Claude Dallas shooting this take place?

It occurred in the area known as Bull Camp,near Bull Basin, very close to the border with Nevada. The 2 game warden's had to traverse a trail from the top of the canyon, down to the bottom, about 3 quarters of a mile, to reach Dallas' camp, which was along the south fork of the Owyhee River. The fact that they might even be in Nevada came up prior to the shooting. It is still, to this date, one of the most remote areas in the West. It is also within close proximity to the Carlin 45 ranch.
