Where to Find Mule Deer in GMU 21
Mule deer in GMU 21 use the Manzano Mountain foothills and the Rio Grande basin breaks. Bucks concentrate in the upper pinon-juniper fringe during archery season and move to lower terrain near agricultural edges during the November rut.
Manzano Mountain Foothills
The western Cibola National Forest slopes hold bucks in scattered mountain mahogany and pinon-juniper patches. Glass from ridge saddles looking down into drainages at first and last light.
Agricultural and Grassland Edges
The basin-edge fields and grassland draws adjacent to the Manzanos attract does during pre-rut, which in turn draws bucks out during November. These transitional areas often hold the largest bucks in the unit.
