Geology at This Park
Eleven Mile State Park has a 3,405 surface-acre reservoir on the South Platte River at the southern edge of South Park. The reservoir, formed by Eleven Mile Canyon Dam, gets water from various creeks like Cross, Prudence, Union, Balm-of-Gilead, Simms and Spring.
The South Platte River Valley is covered with glacial material from the most recent ice age, hiding older formations. Most of the park has very old rocks beneath it from Precambrian times, like Silver Plume granite east and south of Howbert Point, and Pikes Peak granite along the river west of Howbert.
On the west and south edges of the park, there are Thirtynine Mile andesite deposits. Andesite is a kind of igneous, volcanic rock, and Thirtynine Mile andesite is volcanic rock from the extinct Thirtynine Mile volcano area. Cross Creek cuts through another deposit called Trachyte. Trachyte is a kind of igneous, volcanic rock. Steep cliffs along the southwest edge of the reservoir show Wall Mountain Tuff, a kind of rock made of volcanic ash and pumice. Thirtynine Mile andesite covers both granite and Tuff formations on the southern edge of the reservoir.
Habitats and Plants at This Park
Ecologically, the park uplands are dominated by montane grassland and short-grass prairie species, including Arizona fescue, Parry oatgrass, blue grama, needle-and-thread grass, western wheatgrass, Junegrass and squirreltail. Common wildflowers and shrubs include Indian paintbrush, scrub oak, golden aster, gilia, copper mallow, wallflower, sulfur-flower, wild rose, locoweed, fringed sagewort, rabbitbrush and snakeweed. A sparse montane coniferous forest grows on the flanks of slopes and ridges, where both ponderosa and limber pine are present with an understory of mountain mahogany, rabbitbrush, currant and Spanish bayonet.
In moist canyons, Douglas fir becomes the dominant tree, mixing with Colorado blue spruce, ponderosa and limber pines. Stands of aspen grow in shallow soils over bedrock and around rock outcrops along the lower slopes of canyons and drainages, along with shrubby cinquefoil, common juniper, thimbleberry, waxflower, valerian, yarrow and pussytoes.
Diverse wetlands, riparian and aquatic plant communities have become established around the reservoir in seeps, tributary drainages and below the dam. Found here are pale blue-eyed grass and few-flowered ragwort, both considered to be rare plant species.

History
The cultural history of Eleven Mile State Park likely began about 12,000 years ago. Archaeological evidence recovered from surveys in parts of the park indicates that the Folsom, Plano, Archaic and Woodland prehistoric cultures were all present. The earliest year-round inhabitants of the area were the Ute tribes, who found an abundance of wildlife here. The intrusion of the Spanish and French explorers in the 1500s caused the Ute to leave the area temporarily, resettling here during the late 1600s after the first quest for gold was ended.
- 1806: President Thomas Jefferson sends Lieutenant Zebulon Pike with 21 men to explore the South Park Area.
- 1859: The first mining era begins with the rediscovery of gold in the northern and western portions of South Park, and the Ute are once again forced to leave their favorite hunting grounds.
- 1861–1870: Nearly 11,000 miners converge on South Park and establish permanent settlements. Several towns sprout in the Eleven Mile Canyon area. The influx of people leads to the establishment of many trails and wagon roads, which provide a logical route for the railroads to follow.
- 1887: Population growth makes it profitable to open the Colorado Midland Railroad, the first broad-gauge line into the Colorado Rockies. The railroad transports wealthy visitors from Colorado Springs to what is now Eleven Mile Reservoir so that they can enjoy the numerous wildflowers that grow along the banks of the South Platte River.
- 1930–1932: The Eleven Mile Canyon Dam is completed and heralded as an “engineering triumph.” The dam creates the largest artificial body of water in Colorado at the time. The Denver Water Department currently owns the dam, the water and most of the land that surrounds the reservoir. Eleven Mile is one of seven reservoirs that provide drinking water for Denver. Because of the obvious need to protect against pollution, strict regulations prohibiting certain recreational activities are in effect.
- 1960: The Division of Parks and Outdoor Recreation assumes management of the area under a lease agreement with the Denver Water Board.
Today, the waters of Eleven Mile Reservoir cover the ranches and towns that once prospered long ago. The water line cut some ranches in half while others were totally submerged. Surrounding mountains and campgrounds in Eleven Mile State Park have been named after a few of the ranchers whose lands now lie underwater.
