History of Shoshone Indian Ice Cave

Located 15 miles north of the city of Shoshone is the famous Shoshone Ice Caves. The Shoshone Ice Caves are lava tubes believed to be formed 24,000 years ago after the eruption of the nearby Black Butte volcano. Lava tubes are natural tunnels formed when molten lava travels beneath the surface of a lava flow. The flowing lava on top is cooled from the surface by radiation and thermal convection, forming a rigid crust that encapsulates the inner molten lava and allowing it to flow without cooling. The hard crust is eventually drained of the molten lava beneath as the flow discontinued, forming a natural wonder known as lava tubes.

The Shoshone Ice Caves were discovered back in the 1880s by a young boy who stumbled upon the structure while looking for his lost sheeps. The town of Shoshone soon got word of the existence of the underground ice caves. The entrance to the caves was blasted open and ice was hauled out to the Oregon coast to make ice boxes.

The ice-cold caves were also known to stay cool enough for the iceto remain frozen throughout the summer season. As such, the town of Shoshone was popular among travelers during the days when refrigeration was uncommon as it was the only place in the West where iced cold beer was served. During the heydays of Shoshone, it boasted as many as 25 saloons and restaurants.

However, the sprawling entrance allowed hot air to flow in and melt the ice. Combined with the rampant exploitation, little ice was left in the Shoshone Ice Caves by the 1930s. Almost a decade later, the abandoned cave was visited by Russell Robinson, an amateur archaeologist and geologist. In the 1950s, Robinson acquired the Shoshone Ice Caves in hopes of restoring the ice caves to its former pristine conditions. Manmade walls were installed to block the openings and trap the icy air. Every winter year, Robinson would carry out meticulous studies of the air patterns in the cave and observe how the ice was replenished. By the 1970s, most of the ice was back.

Today, there are approximately 300,000 tones of ice in the caves, allowing the tunnels to stay cool between 23 and 33 degrees all year round. A museum, a 30-foot Indian statue—a memorial to Chief Washakie of the Shoshones—and a concrete dinosaur can also be found on the site.
