Location was about 1/4 mile within the Tohono O'odham Indian Reservation which does not allow off road tresspassing. While we were estimating the location from a pullout on the highway, agents of the US Border Patrol stopped to "make sure we weren't doing something that would get us in trouble". Taking pictures was the quick answer since we didn't want to try to explain geohashing (probably at the local substation). We opted for a 2 mile hike at a nearby trailhead.
