Anne U White Trail 

Anne U. White Trail

The Anne U. White Trail is closed due to flood damage. Reconstruction will continue this summer.


Reconstruction of the Anne U. White Trail is underway. We do not have an opening date planned at this time.

In 2015, we did a lot of work and held several volunteer projects. But work has been slow since we are only able to work when water levels are low and when there are no threats of flash floods.

As we have all experienced, the recovery effort is monumental in its size and complexity and many unknowns continue to persist. Our approach to this project may be adjusted as the various other components of the process are further resolved. We will continue to keep all stakeholders informed of our plans and project schedule as they continue to be refined.

As the trail repair project gets closer to completion, we are committed to working with Boulder County Transportation and the neighborhood near the trailhead to minimize conflicts between potential trail use and other flood recovery efforts occurring in the area.

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

We appreciate all the volunteers who've come out this summer to help rebuild Anne U. White! Thanks for another great day! #boco_trails

 ‭(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.
