Candy Mountain Interpretive Loop

Friends of Badger Mountain, in partnership with the local chapter of the Native Plant Society, Ice Age Floods 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.

Trail Features

The CH2M sponsorship of the Candy Mountain Preserve included design and construction of monuments to honor and commemorate the generations of Hanford workers that have helped make the Tri‐Cities the vital and thriving community it is today.

Thirty (30) native plant signs highlighting the Eastern Washington Sagebrush habitat and links below to the University of Washington, Burke Museum website provide lots more information and photos.

During the last ice age, the Tri-Cities experience some of the largest fresh water floods known to have happened anywhere on the plant. This is an incredible part of the geological history that shaped our area. Come and learn more on a gentle walk around the 1.2 mile Candy Mountain Interpretive loop.

Mickie Chamness, Karl Fecht and other have created a geological map of Candy Mountain that is now in the Candy Mountain Kiosk. A new basalt geology interpretive sign is coming SOON explaining about some of the largest overland lava flows know to happen anywhere on the plant. Did you know that our native rock is reddish-brown basalt and that basalt rock is over 1 mile thick in our area from multiple over land lava flows? The basalt outcrops visible in the saddle of Candy Mountain may have flowed over thirty miles from ancient fissures near the modern day location of the Ice Harbor Dam on the Snake River


Native Plants of the Candy Mountain Preserve

The metal native plant signs were a wonderful collaborative effort. The metal signs were made by Columbia Basin College students in their metal welding class. The text and photos were provided by local chapter members of the Native Plant Society. Benton County Commissioner’s office staff did the final layout and formatting. Benton County paid for all the materials and label printing. Friends of Badger Mountain provided project management throughout the process. FOBM volunteers also primed and painted the metal signs, adhered the plant labels and installed the metal plant signs around the interpretive loop.

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.”
