The Great Rift dominates this portion of the Idaho volcanic landscape, stretching across the high desert of Blaine County. This 1970s survey captures a stark geological environment defined by expansive Lava flows and a series of deep earth Cracks that follow the rift line. Geographic markers like New Butte and Bear Park Butte rise above the surrounding volcanic fields, serving as navigational anchors in a terrain largely devoid of modern development.
