Unit 40BWT (Kofa West – White Tank)

Arizona Hunting Guide — Bighorn Sheep

Unit 40B-WT (White Tank) is a specialized desert bighorn hunt covering the west side of the Kofa National Wildlife Refuge, adjacent to the 40B-WG (White Ghost) hunt area. Terrain is classic Kofa desert bighorn country — stacked rimrock, narrow slot canyons, and cliff bands rising from creosote-bursage bajadas. This is one of Arizona's most prized once-in-a-lifetime bighorn draws with tag numbers in the single digits and exceptional ram quality.

Frequently Asked Questions

How do 40B-WT and 40B-WG hunt areas differ?
Both are west-side Kofa hunts with separate tag allocations and adjacent boundaries. Specific ram groups and access logistics differ. Review AZGFD's current regulations for the exact line between White Tank and White Ghost hunt areas.
Can I scout 40B-WT during summer?
Technically yes, but Kofa summer temps exceed 110°F. We prefer October–November scouting when conditions are tolerable and ram groups are forming pre-rut.
Do I need a guide for 40B-WT?
Not legally. Practically, yes — the terrain, water logistics, and ram-finding expertise experienced Kofa guides bring make the difference on a once-in-a-lifetime hunt.
