Adult Cascades frogs have tan, copper or green backs with black spots and yellow bellies. Their skin has small bumps on the back and sides. Females, which grow to three inches in length, are slightly larger than males.

Cascades frogs live in a variety of moist habitats including mountain meadows, bogs, seasonally flooded forested swamps and shallow ponds, marshes and lakes. They use woody debris, mud or dense vegetation for cover from predators and spend their winters hibernating in mud. They emerge during the summer and live in wet meadows and bogs or along forested streams and pond edges.

The Cascades frog is an Oregon Conservation Strategy Species in both the East and West Cascades ecoregions.
