Unit DO-02

Hart Mountain dominates the eastern horizon and serves as a primary navigation anchor. Poker Jim Ridge and Blizzard Ridge run through the unit and provide excellent glassing platforms for scanning the surrounding country. Black Rim offers visual reference along portions of the terrain.

The major drainages—De Garmo Canyon, Hart Canyon, and Sixmile Draw—form natural travel corridors and concentrate deer movement, especially during seasonal shifts. Gray Buttes and the Warner Peak complex provide additional high-ground vantage points for route planning and area reconnaissance.

The unit's terrain climbs gradually from low-elevation sagebrush basins around 4,500 feet up to mid-elevation ridges near 8,000 feet, with the bulk of the country sitting between 5,000 and 6,500 feet. Habitat is predominantly open sagebrush and bunchgrass with scattered juniper woodlands concentrated on ridges and north-facing slopes. The sparse forest cover means glassing opportunities are plentiful—you can scan vast areas from higher vantage points.

Lower elevations are drier, more open grassland; higher ridges host thicker juniper and offer better shelter and bedding habitat during early season.

A network of roughly 450 miles of secondary roads crisscrosses the unit at moderate density, providing fair access to most drainages and ridgelines. Roads are generally passable but not maintained to highway standards. Most hunters concentrate along the main access corridors and near named flats like Lyons Meadow and Spanish Flat, leaving portions of the canyon country less pressured.

The moderate terrain complexity and sparse forest mean much of the unit is walkable once you're in, reducing dependency on perfect road access. Minimal private land means few access restrictions.

DO-02 occupies a moderate-sized block of southeastern Oregon high desert, sitting in the transition zone between the Warner Mountains and the Great Basin. The unit's boundaries encompass multiple drainages flowing through canyons including De Garmo, Martin, and Mulkey, with Hart Mountain forming a natural eastern landmark. Nearly all the unit sits on public land, making it accessible for the entire hunting season.

Nearby communities provide staging points, though the unit itself is remote enough to avoid heavy day-use pressure from populated areas.

Water is the limiting factor in DO-02. A network of springs scattered throughout provides reliable access: Poker Jim Spring, Antelope Spring, Indian Springs, Cottonwood Spring, and Hot Springs mark dependable water sources. Multiple small lakes and ponds—including Poker Jim Lake, Petroglyph Lake, Spanish Lake, and Twin Lakes—offer additional options, though some are seasonal. Willow Creek, Juniper Creek, and Deer Creek provide perennial flow in their lower reaches.

Understanding water locations is essential for both deer location and camp planning; most hunting will center within reach of known springs and creeks.

This is mule deer country, with white-tailed deer present in wetter canyon bottoms and riparian areas. Early season hunting focuses on higher ridges and north-facing juniper slopes where deer bed during warm days. The open terrain rewards glassing—find vantage points on ridges and glass the surrounding sagebrush for feeding deer during morning and evening.

Mid-season, water becomes the hunting tool; position near springs and creeks where deer concentrate, especially around Poker Jim Spring and the major canyon systems. Late season pushes deer toward lower elevations and thicker juniper cover. The limited forest cover means you'll be spot-and-stalk hunting more than threading timber; rangefinding and marksmanship matter here.
