Inscription. When its water is not diverted for upstream irrigation, Lost River flows past here into a sink 14 miles to the northeast.

Lava flows in the Snake River plains buried old channels of Lost River, Little Lost River, and Birch Creek. No longer able to reach the Snake on the surface, they went underground. After a 120 mile journey under the lava plains, water from Lost River eventually emerges through numerous large springs below Twin Falls, making up a small part of the Thousand Springs near Hagerman.
