INFO: Elk Hunting in New Mexico Unit 55B
The first archery season can see extremely high temps. Water is abundant in most of the unit, but stand hunting over wallows can be effective. Hunters with tags for this season should consider hunting during the last part of the season, bugling to locate bulls. The later archery season takes place during the rut.
