Unit Cache, East Rich
High-elevation plateau country straddling Utah, Idaho, and Wyoming with abundant water and scattered timber.
Hunter's Brief
East Rich sits on a moderate-elevation plateau bounded by the Utah state lines, featuring a mix of open country and sparse forest with excellent water availability. Multiple reservoirs, springs, and perennial creeks make this unit attractive for high-country hunting. Access via US-89, SR-30, and SR-16 provides fair entry points, with a reasonable network of roads reaching into the unit. The relatively flat topography compared to surrounding mountain ranges makes navigation and glassing feasible, though terrain complexity remains moderate. Elk, moose, mule deer, and pronghorn find habitat here; higher elevations support goats and bighorn sheep in steeper drainages.

Terrain Deep Dive
Landmarks & Navigation
Bear Lake dominates the western landscape, with multiple beaches and developed areas providing clear orientation reference. The Crawford Mountains form a notable ridge system; Hogback Ridge and Lake Ridge offer elevated vantage points for glassing. Rex Peak and Black Mountain serve as prominent summits for navigation and visual landmarks.
South Eden Canyon and its various branches create significant drainages cutting through the plateau, offering travel corridors and water sources. The Eden Reservoirs—Upper North Eden, South Eden, Lower North Eden, and Sixmile—mark reliable water locations and natural gathering areas for wildlife. These landmarks combine to create a navigable landscape with clear terrain features.
Elevation & Habitat
The unit spans medium-elevation country from roughly 5,900 to nearly 8,000 feet, creating a plateau environment with scattered timber and open parks. This elevation band supports transition habitat where lower sagebrush flats meet ponderosa and juniper-dotted ridges and slopes. The sparse forest coverage means significant open country for glassing and movement, interspersed with stands of timber offering cover and thermal relief.
Spring green-up occurs relatively early at these elevations, and early winter snows can push animals downslope. The mixed open-and-timbered landscape creates distinct thermal corridors and movement patterns through the unit.
Access & Pressure
US-89, SR-30, and SR-16 provide primary access with fair connectivity through the unit, supported by 260 miles of roads creating opportunity for multiple entry points. The relatively flat topography and road network make the country less isolating than steeper terrain units, suggesting moderate hunting pressure in accessible drainages and near water sources. Woodruff, Randolph, and smaller communities nearby offer staging areas for logistics.
The state border access means hunters may encounter activity from adjacent Idaho and Wyoming hunters, especially near boundary drainages. Spreading effort across the unit's water sources and varied terrain helps avoid concentration on popular routes.
Boundaries & Context
East Rich occupies Rich County's northeastern corner, bounded by the Utah-Idaho state line to the north and west, the Utah-Wyoming state line to the east and south. US-89 marks the western boundary near Garden City, while SR-30 and SR-16 define access routes through the unit. The unit sits east of Cache Valley and south of the Bear Lake area, creating a distinct geographic island between major state borders.
This location puts it at the intersection of three states' wildlife management areas, making coordination and access unique. The surrounding terrain transitions from lower valley floors to higher plateau country, positioning East Rich as a bridge between distinct ecosystems.
Water & Drainages
This unit excels for water availability—reservoirs, lakes, and springs are abundant throughout. Bear Lake itself provides massive water presence to the west. The Eden Reservoir system on the eastern slopes captures runoff, while South Lake and North Lake offer additional standing water.
Perennial creeks including Sheeppen Creek, North Fork Sixmile Creek, Sage Creek, Swan Creek, and Big Creek provide reliable flow, critical for predictable animal movement and hunter logistics. Numerous named springs—Hidden, Red, Divide, Rich, Rock, Sheeppen, Rabbit, Shirley, Cottonwood, and Cold—dot the unit. The abundance of water reduces the pressure of finding reliable sources and allows for flexible hunting strategy across the entire unit.
Hunting Strategy
East Rich supports a diverse species palette: elk use the timbered slopes and canyons for cover, with movements tied to elevation and seasonal water; moose inhabit wet drainages and reservoir edges; mule deer occupy the open-timber mix throughout; pronghorn favor open sagebrush flats. Higher country supports mountain goats on canyon walls and bighorn sheep on ridges, particularly in South Eden and related canyons—terrain features guide these animals to predictable escape routes. Early season hunting can target high-elevation parks before animals descend; rut movement follows the canyon drainages where water concentrates animals.
The abundant water sources mean animals aren't forced to concentrate, requiring hunters to glass thoroughly and cover ground methodically rather than rely on water-hole ambushes.
