Cedar Creek Springs is a huge karst spring, the resurgence of an underground river at the foot of the Lost River Range. The impressive cave entrance with the cave strem froming a cascade is easily visible from the trail.

The Lost River Range is composed of Proterozoic and Paleozoic sedimentary rocks, including limestone. The limestones are karstified, there are numerous caves and karst springs. The water from the springs flows into two rivers, the Big Lost River and the Little Lost River. Both rivers flow into the Snake River Plain and are swallowed by sinkholes. So they both end in the middle of the plain. The water reappears in Snake River in the south.
