Candy Mountain Interpretive Loop

Friends of Badger Mountain, in partnership with the local chapter of the Native Plant Society, Ice Age Flood Institute, and Benton County, established the Interpretive Loop Trail in the saddle of Candy Mountain. The loop is 1.2 miles long (round trip) starting from the parking lot and has very little elevation gain.

Basalt Rock

The reddish-brown rock that we see all around us here in the Columbia Basin is a volcanic rock called basalt.  It erupted from giant fissures in the Earth’s surface in a series of events between 6 and 17 million years ago, covering thousands of square miles of Idaho, Oregon, and Washington to a depth of over 2 miles in some places.  Collectively, these volcanic flood episodes and the rock they created are called the “Columbia River Basalt Group.”
