Also in Colorado, west of Pueblo, there is a "Little Owl Canyon" - an area well known to rockclimbers.

Owl Canyon is also an unofficial name of a canyon on the west side of Bodega Bay, near Bodega Head in Sonoma County, California, U.S.A. The area is a well known birding spot, and there are actually Owls living there!
