A now-inactive fissure cuts the surface of a sinter mound at Steamboat Springs in Nevada. Steam from a hot springs rises at the upper left. Steamboat Springs, an area of active geothermal development, currently displays hot springs, a large number of steam vents and fumaroles structurally related to regional faults. The area once contained about 20 small geysers, but none are currently active.
