Anne U White Trail 

Anne U. White Trail

The Anne U. White Trail is closed due to flood damage.

Trail Reconstruction

Trail reconstruction is nearly complete. A lot of progress was made this year thanks to several volunteer projects and lots of hard work by our trail crew. Work includes over 25 technical structures such as stream crossings and steps. We expect to complete the trail work through the winter, weather permitting, with restoration plantings planned for the spring.

Area Still Closed

There are other flood recovery projects along Fourmile Canyon Creek that need to be completed before we can open the trail, including repairing the road and managing potential buyouts of homes that were damaged in the flood.

Road Reconstruction

The design and construction of the road and stream is being managed by the Boulder County Transportation Department. Construction is scheduled to begin this winter. Updates are posted on Wagonwheel Gap Road Reconstruction.

Property Buyouts

The buyouts may change how the entrance to the property is rebuilt. The potential buyouts are being managed by the Boulder County Land Use Department. Land Use cannot provide information about potential buyout properties until after the buyout is complete. When we know what properties will be bought out, we will be able to make plans for the trailhead and share that information.

Opening Date Unknown

At the present time, we do not know when the trail and trailhead will reopen. We are working with Transportation and Land Use to determine what that timing might be in light of the work those departments plan to undertake.

We appreciate your patience, input, and assistance in the county's endeavors as the recovery process continues to evolve.

 ‭(Hidden)‬ Plants & Animals

Along Colorado’s Front Range the sweeping grasslands of the Great Plains rise to meet the rugged peaks of the Southern Rocky Mountains. Where they meet we find the foothills – a zone of geological and biological transition. Foothills ecosystems are made up of myriad landforms such as cliffs, canyons, hills, and plateaus. Plant communities range from grasslands to shrublands to forests which provide a variety of habitats for a rich diversity of animals.

 ‭(Hidden)‬ History

The Name

The Anne U. White Trail is named in memory of Anne Underwood White, a dedicated environmentalist, scientist and open space advocate, who donated 20 acres for the creation of this trail.

The Land

Except during times of logging, Fourmile Canyon Creek has always been roadless. Some of the land to the south of the trail was homesteaded in the mid-1800s by a Welsh miner who cleared the timber and cultivated crops on the gentler slopes. It was also grazed by cattle in the summer. Much of it bears the scars of mineral prospecting and one pit became an operating mine. Most of the native ponderosa pine and Douglas fir forest in Fourmile Creek Canyon was extensively logged in the late 19th century.
