Located just off Highway 395 between the town of Pilot Rock and the unincorporated community of Nye. This is a small gravel area where a lot of locals shoot. I've gone shooting there on numerous occasions and have never been bugged by anybody claiming to be the property owner. If you're gonna shoot here, be conscious about the highway literally adjacent to the shooting spots.
UPDATE: Asked some locals around Pilot Rock about the shooting pit and they say thats been the spot to shoot for probably the last 15 years or so. The clerk at the Shell Gas Station said that the owner of the property resides in Arizona during winter and Oregon during summer. Apparently he doesn't mind people shooting as long as they pick up after themselves.
