The Anne U. White Trail is named in memory of Anne Underwood White, a local writer and open space advocate who donated 20 acres for the creation of this trail.
The Anne U. White Trail follows Four Mile Canyon Creek through a narrow canyon hemmed in by dense forest and steep rock walls. Ponderosa, fir, aspen, cottonwood, willow, and maple line this richly appointed riparian corridor. A leafy understory yields a diverse collection of summer wildflowers and brilliant autumn colors.
Perennial water, flowers, abundant natural edibles and shelter attract an array of wildlife including hummingbirds, deer, fox, coyote, bobcat, bear and mountain lion. This gentle trail welcomes individuals of all abilities, families, dogs, trail runners and winter recreation.
The trail heads west from the parking area and quickly joins the creek, rising nominally to the first of several easy crossings (.55 miles : 6,165'). The trail negotiates quick intervals of thick timber, narrow passages and small hillside clearings to a 5' cascade that drops into a shallow pool (1.35 miles : 6,418'). A false trail veers steeply above and to the right of this fall; ignore it and simply continue straight over its level top. The trail resumes an undulating course to its terminus at a well-marked point (1.6 miles : 6,530').
