Unit Rattlesnake Hills

The Rattlesnake Range forms the unit's backbone, with named summits like Elephant Mountain, Snipes Mountain, Gable Butte, and Lookout serving as key navigation and glassing points. Horsethief Point and The Horn provide additional vantage locations for surveying the sagebrush basins below. The Yakima River corridor, Rattlesnake Creek, and major drainages like Washout Gulch and McCoy Canyon function as travel routes and water-finding reference points.

Smaller features like Union Gap and The Gap mark natural passes through ridge systems. The Roza Wasteway and various canals, remnants of irrigation infrastructure, create additional linear features useful for navigation.

Terrain spans lower-elevation country from near sea level at the Columbia River to roughly 3,600 feet atop the highest ridges, with most hunting occurring below 2,000 feet. Sagebrush dominates the open flats and gentle slopes, with scattered juniper and cheatgrass covering hillsides. Vegetation is sparse overall—this is semi-arid steppe rather than forest country.

Riparian cottonwood corridors follow the Yakima River and major creek bottoms, providing small pockets of denser cover. The landscape transitions gradually rather than showing distinct zones, with sagebrush gradually thickening into patchy juniper as elevation increases.

A substantial road network—over 2,200 miles total—provides connected access throughout the unit, with secondary roads reaching most areas. Major towns like Yakima, Ellensburg, and Grandview sit at the unit's periphery, making access straightforward. However, significant private land ownership limits where hunters can legally roam.

The flatter terrain and road access create moderate hunting pressure, particularly in accessible sagebrush areas near developed land. Less-visited country exists in the higher ridge systems and more remote drainages, especially where roads end and foot travel becomes necessary. The Yakima Training Center boundary to the east restricts access in that direction.

The Rattlesnake Hills unit occupies the region between the Columbia River to the north and east, bounded by the Yakima River to the west and SR 823 to the south. The Yakima Training Center forms the eastern boundary, with the town of Yakima sitting just beyond the western edge. This is semi-arid plateau country in south-central Washington, where the Cascade rain shadow keeps precipitation low and vegetation sparse.

The unit encompasses rolling foothills and ridge systems rather than true mountains, with elevations climbing from riverside flats to modest summits rarely exceeding 3,600 feet.

The Columbia River forms the northern boundary, providing reliable but often inaccessible water due to dams and private land. The Yakima River offers another major water source along the western edge. Perennial creeks like Rattlesnake Creek, Cold Creek, and Spring Creek provide seasonal to year-round flow in major drainages.

Scattered springs dot the foothills—Sam White Spring, Railroad Spring, Two Spring, and others—though reliability varies seasonally. Much of the upland sagebrush country is dry, with hunters relying on spring locations and occasional seeps. Water planning is critical for extended backcountry trips in the open ridge country.

The Rattlesnake Hills support black bear and mountain lion in sagebrush and juniper country. Bear hunting focuses on spring feeding in riparian areas and lower drainages where vegetation greens up first, with fall hunting in upland areas where bears forage on berry crops and transition toward winter dens. Lions hunt the sagebrush flats and juniper breaks year-round, following mule deer populations.

Glassing from ridgetops like Elephant Mountain and Snipes Mountain can reveal both lions and potential prey. The open, lower-elevation terrain means predator hunting relies heavily on spotting and stalking rather than driving drainages. Water sources become crucial for locating both species, particularly during dry periods.
