Water Source: Unicorn Creek

Waterfall Description: Unicorn Creek flows from Snow Lake, over the edge of a lava flow via a series of cascades, finally dropping 125 feet to the canyon floor over Martha Falls. The falls were named for Martha Longmire by one of her sons while he was working on the Wonderland Trail in Stevens Canyon.

Viewing Location: The main falls can be seen across the upper end of Stevens Canyon from a viewpoint along the road. A higher cascade of Martha Falls is visible along the Wonderland Trail about 0.6 miles from where the trail crosses the upper portion of Stevens Canyon Road, or 4.2 miles from the Reflection Lakes parking area. Continue an additional 0.9 miles down the Wonderland Trail to view Sylvia Falls.
