The road alongside the drainage to the reservoir. I'm hiking west. You can barely see the 50 ft wide dam my dad and Uncle Bud built in 1956. The Romain Bros. built a lot of dirt dams back in the 40s as the gov't paid them to do so. They would do this work after seeding until the snow fell. If you look at satellite of the area, the reservoirs that have dams are definitely squared on one side.
