These are excellent trails to explore the grassland ecosystem and the lower range of the ponderosa pine forest. Mule deer commonly graze this area in the early morning. Coyote and fox can also be observed. The area also provides hunting grounds for many of our local raptors. In early May, wild irises bloom in great numbers along the upper Big Bluestem trail.
