Fort Rock, Oregon

Elevation ranges from approximately 4,000 feet on the sagebrush flats east of Silver Lake and Christmas Valley to over 9,200 feet in the high Cascades along the western boundary near the Pacific Crest Trail. The unit transitions from rugged, timbered Cascade foothills in the west—including pumice-soaked plateaus and lava flows characteristic of the Fort Rock-Christmas Lake Valley basin—to broad, flat alkali playas and marsh complexes near Silver Lake in the east. Walker Rim, rising steeply above the western interior, is a prominent landform. Volcanic rimrock, cinder cones, and ancient lava fields are common across the central and eastern portions.

Primary highway access via US-97 (north-south corridor through the unit) and OR-31 (east-west through Silver Lake). OR-58 forms the northern boundary near Crescent. County roads provide access along the eastern portion toward Christmas Valley. The western half is managed by the Fremont-Winema and Deschutes National Forests; the eastern and central portions fall within BLM Lakeview District. An extensive network of paved, gravel, and dirt Forest Service and BLM roads accesses the majority of the 65% public land. Key travel restrictions: (1) the Cabin Lake-Silver Lake Winter Range is closed to motor vehicles December 1 through March 31; (2) the Walker Rim Travel Management Area imposes seasonal road closures from three days before the general rifle deer season through the end of season; (3) Sugar Pine and North Paulina areas carry permanent road restrictions. The Pacific Crest Trail traverses the far western boundary. Crater Lake National Park is closed to big game hunting. Nearest services: Silver Lake, Chemult, Gilchrist, La Pine (north), and Lakeview (south via Hwy 31). ODFW contacts: East Fort Rock (Lakeview 541-947-2950 or Summer Lake 541-943-3324); North Fort Rock (Bend 541-388-6363).

The western and north-central portions carry mixed conifer forest dominated by ponderosa pine, lodgepole pine, white fir, and mountain hemlock, transitioning to whitebark pine and subalpine fir near the Cascade crest. The mid-elevation interior features extensive logged and regenerating lodgepole pine stands with abundant grassy openings and meadows. Moving east, forest gives way abruptly to juniper-sagebrush steppe and bitterbrush shrubland on the Fort Rock volcanic tablelands and Christmas Valley floor. Irrigated alfalfa fields near Silver Lake provide important agricultural forage. Riparian corridors follow Paulina Marsh, Silver Lake, and Crescent Creek on the western portions.

Mule deer are the dominant big game resident, using the higher timber and bitterbrush zones in summer and shifting to lower sagebrush-juniper winter ranges near Silver Lake and the Fort Rock basin as snows arrive. Rocky Mountain elk occupy the timbered Cascade slopes and ponderosa-lodgepole zone, with the herd split by Hwy 97 between the Paulina-East Fort Rock (east of 97) and East Central Cascades (west of 97) populations; elk migrate to lower elevations in winter. Pronghorn antelope occupy the open sagebrush and grass flats of the eastern unit, particularly the Christmas Valley-Silver Lake corridor. Black bear are present throughout the forested western half. Cougar range the entire unit following deer and elk. Mule deer and elk use the irrigated alfalfa fields near Silver Lake as supplemental forage. Migratory waterfowl concentrate on Silver Lake, Paulina Marsh, and other playas seasonally.

1. ELK OTC CORRECTION: The draft incorrectly stated Unit 77 elk was available on a general OTC any-legal-weapon tag (units 43-77, Sep 1-Nov 15). Verified via eRegulations: Unit 77 is NOT listed in any general season elk zone. All elk hunting in Unit 77 requires controlled draw tags (235X, 235Y, 234X, 235M, 234M). Archery elk status should be verified annually. 2. PUBLIC LAND PCT: ODFW unit page cites 65% public land for the overall unit; GoHunt reports 70%. ODFW figure (65%) used as primary. The Paulina-E Fort Rock elk/pronghorn hunt areas are separately cited at 70-75% public land. 3. DEER 2026 TRANSITION: Beginning 2026, ODFW transitioned eastern Oregon mule deer from WMU-based hunts to new Deer Hunt Areas. Hunt 177 area maps to the Devils Garden (DG) series; the specific DG code could not be confirmed from readable web sources — verify with ODFW. All deer hunting remains controlled draw. 4. ELK HARVEST STATS: 2024 elk figures (235X: 7% success/11 bulls; 235Y: 9%/9 bulls) are for Paulina-E Fort Rock controlled hunts covering Unit 77 east of Hwy 97 only. 234X E Central Cascades (west of Hwy 97) showed near-zero harvest in 2024. General-season elk harvest not applicable — Unit 77 has no general OTC elk season. 5. PRONGHORN TAG QUOTA: ~40-tag quota from 2025 proposed regulation draft covers both Units 76 and 77 combined (476A). Unit-77-specific portion not separately quantified. 6. BIGHORN SHEEP/ROCKY MOUNTAIN GOAT: 500-series and 900-series hunts referenced on ODFW unit page but no confirmed active hunt areas within Unit 77 identified in eRegulations descriptions. Not included in species array. 7. NATIONAL FORESTS: ODFW page lists Deschutes, Winema, and Fremont NF. The Winema and Fremont were administratively combined into the Fremont-Winema NF. Draft updated to reflect both Fremont-Winema and Deschutes NF coverage in the summary.
