| Notes | E. 56th Ave. between Rocky Mountain Arsenal NWR and 1st Creek at DEN Open Space which borders the South end of the NWR was closed for road repair necessitating our going on streets further south – so we may have potentially missed a few raptors. The distance driven was 72.6 miles and the time taken was 7 hours and 44 minutes for the entire route. | |
