Inscription.
The Heart Mountain Division of the Shoshone Project receives irrigation water directly from Buffalo Bill Reservoir via the Shoshone Canyon Conduit, a three-mile-long tunnel drilled through Cedar Mountain located to the left. From the conduit, the water travels over the Shoshone River through the Shoshone River Siphon and into the 28-mile-long Heart Mountain Canal. The siphon, completed in 1938, is 1,640-feet-long and at the time of construction was the longest self-supporting pipe span in the world. From the siphon, the water travels through a short tunnel in Rattlesnake Mountain, across the river to the right, and into the Heart Mountain Canal System.

About 31,120 acres are irrigated on the Heart Mountain Division of the Project, which was settled beginning in 1946.

The Heart Mountain Power Plant, not visible from this vantage point, but shown in the photograph, has a generating capacity of 6,900 kVA and is one of four hydropower generating facilities using water from Buffalo Bill Dam.
