Flora & Fauna

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. In the 2,871 acres that make up Rabbit Mountain, plant communities ranging from grasslands to shrublands to forests provide a variety of habitats for a rich diversity of wildlife

Geology

About 140 million years ago this area was a tropical lowland covered by rivers, swamps, and lagoons. Much of Colorado was below sea level and covered with an inland sea for millions of years.

This sea retreated around 65 million years ago when forces deep within the earth began uplifting the Rocky Mountains. These mountain-building forces created tension in the rocks around Rabbit Mountain, causing them to break. Movement along such a break is called a fault. A major fault extends across the north end of the property. Slippage along area faults has caused Rabbit Mountain to be positioned three miles east of the main hogbacks of the foothills. Because of this location, you can see Rabbit Mountain from three counties.


History

Native Peoples

Rabbit Mountain was an ideal winter home for the Arapaho Indians, providing them with shelter from the strong west winds, a variety of edible plants, water from naturally-occurring springs, and an abundance of game. It is rumored that the Arapaho Chief Niwot may have spent considerable time in the area.

Homesteaders Arrive

In the middle of the 19th century, homesteaders took up land in the area, hoping to strike it rich prospecting for gold. Few homesteaders were successful, with many turning to farming as an alternative. Their arrival marked the Native Indians’ displacement at Rabbit Mountain, as well as the entire state.

Western Water

In 1959, the St. Vrain Supply Canal was constructed across Rabbit Mountain as part of the Colorado Big Thompson Project. Still operational, the project was designed to carry water through the mountains from the relatively lush western slope to the semi-arid Front Range.

Acquisition

Jack Moomaw was a forest ranger and had a strong desire to preserve wilderness areas, including Rabbit Mountain. These aspirations were realized when his granddaughter sold Rabbit Mountain to Boulder County in 1984. Because of this acquisition, Rabbit Mountain will be preserved in its natural state for many generations to enjoy.
