Unit 77

Preston serves as the primary orientation point, with Highway 34 providing a clear north-south reference. Major basins—Franklin, Horse, Copenhagen, and Cub—create geographic anchors for navigation across open country. Oneida Narrows Reservoir and Glendale Reservoir are conspicuous water features visible from distance, useful for orientation and water location.

Morgan Ridge and Rocky Peak offer elevated vantage points for glassing surrounding terrain. Mink Creek, Foster Creek, and Deep Creek provide named drainages for travel and navigation. The populated places—Cleveland, Nashville, Cherryville—mark community centers and logical staging points for hunters unfamiliar with the area.

Elevations span from lower valley floors around 4,500 feet to ridgeline terrain approaching 9,400 feet, creating distinct habitat transitions across the unit. Lower elevations feature open basins and agricultural valleys with scattered cottonwoods and willows, while mid-elevations transition into sagebrush slopes with ponderosa and juniper. The highest terrain supports denser forest stands and rocky ridgeline habitat.

Morgan Ridge, Cleveland Hill, and Rocky Peak provide elevated terrain with views across multiple basins. This vertical relief creates natural migration corridors for wildlife, with seasonal movement patterns following available forage and water. The moderate forest coverage indicates a mosaic landscape rather than continuous timber, offering both glassing opportunities and timbered shelter.

The 553 miles of total road mileage indicates a well-connected network, with State Highway 34 and U.S. 91 providing major corridors. Secondary roads connect to most basins and lower ridgeline terrain, creating fair accessibility for conventional vehicles. The presence of multiple small communities and significant private land suggests hunting pressure concentrates around accessible public parcels near roads and reservoirs.

Preston and Cleveland function as primary staging areas with full services. The rolling topography and road network make much terrain accessible to foot traffic from road corridors, concentrating typical pressure on lower elevations and near water. Steeper terrain toward higher ridges likely receives less pressure due to distance and effort required.

Unit 77 occupies the Franklin County portion of southeastern Idaho, bounded by U.S. 91 and the Idaho-Utah state line to the south, with State Highway 34 forming part of the northern boundary near Cleveland. Preston serves as the geographic center and primary reference point for the unit. The unit encompasses rolling foothill country between major population centers, creating a landscape where agricultural land, private holdings, and huntable terrain intermingle.

Danish Pass provides elevation relief to the surrounding basins. The road network connecting Preston, Nashville, Cleveland, and smaller settlements creates a networked landscape requiring careful navigation of public versus private access.

The unit contains multiple reservoirs including Oneida Narrows, Glendale, Johnson, Foster, and Lamont, providing concentrated water sources where wildlife congregates. Perennial streams include Mink Creek, Foster Creek, Deep Creek, Litz Creek, and Strawberry Creek, which drain various basins and create natural movement corridors. Dry Creek and its South Fork live up to their names seasonally, requiring verification before planning water-dependent hunting.

Several named springs—Mink Creek Spring, Bergquist Spring, Litz Spring, Log Spring—offer reliable water in upland terrain, though their consistency varies seasonally. The limited overall water rating suggests reliable sources exist but require knowledge of their location and seasonal availability. Irrigation canals serving Preston area agriculture indicate human development's influence on water management.

Franklin County Unit 77 occupies foothill terrain historically used by mule deer and elk moving between lower valleys and higher ridges seasonally. The mix of open basins and timbered slopes provides habitat for both species, with deer utilizing sagebrush transitions and elk favoring timbered upper elevations. Early season hunting can focus on higher basins and ridgelines where cooler temperatures concentrate animals; mid-season rut activity follows the timbered drainages; late season pushes game toward lower elevations and open country as snow builds.

Water sources—particularly reservoirs and perennial creeks—concentrate animals during dry periods. The populated nature of Franklin County and mixed ownership pattern requires careful route planning and early public land identification. Glassing from elevated points along Morgan Ridge and Rocky Peak offers longer-range opportunities, while timbered drainages require closer approach tactics.
