 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.

 History

From Mountainside to University

A quarry can be seen along Hall Ranch’s eastern side. Stones from here were used in many of the University of Colorado Boulder’s buildings, giving it its signature flagstone look.

Hall Ranch as Home

Originally, the property that is now Hall Ranch was home to Arapaho and Cheyenne Indian tribes. In the 19th and 20th centuries, more than 20 different Anglo families homesteaded here. From the mid 1940s to 1993, Hallyn and June Hall owned and operated the ranch.

Historic Buildings

The Nelson House, located along the Nelson Loop Trail, is the remnants of an old homestead from the early 20th century.

Acquisition

In 1993 and 1994, Boulder County Parks and Open space acquired Hall Ranch.
