Red-tailed hawks love it, and you will too. This site connects the Mason Street Trail to Fossil Creek Trail with an underpass under U.S. Hwy 287/College Ave for safe travel.

In addition to recreational enjoyment on the trail, this natural area provides visual relief for those traveling on U.S. Hwy. 287 south of Harmony Road.

Eighty one species of birds have been seen here including its namesake, red-tailed hawks (which have nested here), ferruginous hawks, northern saw-whet owls, and yellow-bellied sapsuckers.
