Unit 10

Several low buttes and ridges serve as effective navigation aids and glassing platforms: Gray Butte, Black Butte, and Pinnacle Rocks provide visual anchors across an otherwise uniform landscape. The Cow Creek Buttes and Miller Hills dominate the central terrain and offer elevated vantage points for long-range observation. Robertson Flat provides another navigational reference.

Named valleys and draws—Philips Draw, Underwood Draw, Willow Draw, and others—cut the flats and create terrain funnels worth hunting. These features help break up the monotony and concentrate deer movement.

The unit sits entirely in the lower-elevation plains zone, a relatively narrow band of high-desert grassland and sagebrush that characterizes northeastern Wyoming's transition country. Vegetation is sparse—big sagebrush dominates the flats with native grasses interspersed, while scattered juniper and isolated cottonwoods follow drainage bottoms. The occasional butte or ridge provides topographic relief, but this is fundamentally open country where visibility often extends for miles.

No forest canopy to speak of means exposed terrain where weather and light dominate the hunting experience.

Over 400 miles of county and forest roads provide access, though density remains low across the vast unit. The road network is functional rather than extensive—you'll use county roads to reach staging areas and hunt from there. This sparse accessibility means most hunters cluster around known access points and reservoirs, leaving significant portions under-hunted.

The straightforward terrain and limited water sources create predictable pressure patterns. Early season and mid-week efforts can avoid the concentrations around main entry corridors.

Unit 10 occupies a substantial portion of the high plains straddling Converse and Niobrara Counties in northeastern Wyoming, bounded by WY Highways 59 and 450 to the north and west. The unit encompasses rolling prairie with scattered buttes and draws cutting through otherwise open country, anchored by landmarks like the Cow Creek Buttes and Miller Hills. This is genuine ranch and grassland country, with the Thunder Basin National Grassland forming its western boundary.

The terrain feels spacious and relatively unbroken—big country with few trees and limited natural barriers to movement.

Water is the limiting factor in this unit. Scattered reservoirs exist—Reno Number 1, Beckwith, Porcupine, Middle Creek, and others—but these are spaced across a large area and not always reliable. Seasonal creeks including Owl Creek, Wildcat Creek, Horse Creek, and Spring Creek provide temporary water but shouldn't be counted on through a hunt.

A handful of named springs (Red, Hansen, Esau) mark more reliable pockets. Hunters must research water locations before entering and plan water strategy carefully, especially during dry periods.

Unit 10 holds mule deer and whitetail, both species adapted to these high plains. Mule deer prefer the open buttes and ridges where they bed on elevated terrain and move to draws and flats for water and feed. Early season finds them high; as it cools, they move lower.

Whitetails concentrate around riparian corridors and draw systems where brush provides cover. Hunting strategy depends on water and season: glass buttes and ridges for mule deer movement, scout creek bottoms and draws for whitetails. The open nature of the country favors long-range optics and patience over bushwhacking.

Plan your water sources first.
