South of Denver, the terrain gradually rises toward the Front Range foothills and the broad Palmer Divide. Drained by Plum Creek and its tributaries, this region has been dissected into a scenic landscape of valleys, ridges and mesas; scrub grasslands cover the lower elevations, juniper and oak thickets adorn the valley walls and stands of ponderosa pine spread across the higher terrain.
Long used for cattle ranching, industry and urban development have spread through the valley over the past century and, in recent decades, suburban sprawl has invaded the uplands. Nevertheless, if one gets away from these sites of human impact, it is easy to appreciate the natural beauty that once characterized all of the Plum Creek Valley. Mule deer are especially common here, feeding along roadways and foraging on the hillsides. Elk winter in the valley and the howls of coyotes echo across this spectacular terrain. Magpies, scrub jays, crows and flickers lend their voice to the wild landscape while golden eagles, prairie falcons, great horned owls and a variety of hawks patrol the region. Though seldom encountered, mountain lions also inhabit the area, attracted by the large deer population.
Such piedmont landscapes, blending the High Plains with the Rocky Mountains, add to the natural diversity of the Front Range environment and offer spectacular settings for wildlife observation. Unfortunately, they also offer appealing sites for residential development and, over time, the natural ecosystem falls victim to human occupation.
