Overview
Jackknife JK-01 is one of ODFW's new-for-2026 eastern Oregon Deer Hunt Areas, drawn around a Columbia Plateau mule deer herd rather than the old unit lines. It runs from the Columbia River between the Deschutes River mouth and Arlington south through Sherman and western Gilliam counties to Fossil, Antelope, and the Hwy 97 country near South Junction. In legacy terms this is the Biggs unit (43) east of the Deschutes — the old E Biggs and W Biggs hunt ground on either side of the John Day River — plus most of the old Maupin unit (40) plateau in the southwest, and it inherits the country of the storied John Day Canyon late-season buck hunt. Only about 12 percent of the area is public land: this is dryland wheat, CRP, and canyon ranch country, and the honest story is that most of the deer live on private ground or in the John Day and Deschutes canyon systems. Expect an opportunity-class mule deer hunt that rewards landowner relationships and hard canyon glassing, with a genuine once-in-a-lifetime bonus: the lower John Day and east-bank Deschutes canyons hold some of Oregon's best California bighorn herds.
Terrain
Rolling dryland-wheat and bunchgrass plateau slashed by two major desert river canyons. The John Day River winds through the middle of the area in a deep basalt canyon (Cottonwood Canyon country), and the Deschutes canyon forms the western edge. Between the rivers it is open, windswept farm and range ground with long sightlines; the hunting compresses into the canyon rims, side draws, and brushy creek bottoms where deer find shade and cover.
Cover: Winter wheat, stubble, and CRP grass on the plateau; bluebunch wheatgrass, sagebrush, and scattered western juniper on canyon slopes and rims; hackberry, willow, and alder strings along the John Day, Rock Creek, and other creek bottoms.
Landmarks: John Day River (lower Wild & Scenic canyon) · Deschutes River canyon (east bank) · Cottonwood Canyon State Park (Hwy 206 crossing) · Columbia River / I-84 corridor (Biggs Junction to Arlington) · Hwy 19 (Arlington–Condon–Fossil, east boundary) · Hwy 218 (Fossil–Antelope, south boundary) · Shaniko–Bakeoven plateau (southwest) · Rock Creek (Gilliam County)
Access
ODFW lists the area at about 12 percent public land, and most of that is concentrated in the two river canyons. The lower John Day is a Wild & Scenic corridor with scattered BLM parcels best reached by boat or long walks; ownership is checkerboarded, so carry a good land-ownership map and verify every parcel. Cottonwood Canyon State Park (roughly 8,000 acres at the Hwy 206 crossing) allows hunting outside its developed areas and is the easiest walk-in public block in the area. The Deschutes canyon's east bank has BLM and state recreation land along the lower river. Everything else is private dryland wheat and canyon ranch country — door-knocking, fee access, or the private-lands and landowner-preference route is the realistic path for most of the area. Check ODFW's Oregon Hunting Access Map for any current Access & Habitat properties before you go.
Managers: Private wheat and ranch lands (large majority), BLM Prineville District (lower John Day and Deschutes canyon parcels), Oregon Parks & Recreation (Cottonwood Canyon State Park, J.S. Burres/Deschutes river sites)
Access points: I-84 exits at Biggs Junction, Rufus, and Arlington (north side) · Hwy 206 to Cottonwood Canyon State Park and the John Day crossing · Hwy 19 through Condon toward Fossil (east boundary) · Hwy 97 through Grass Valley and Shaniko (southwest) · Boat launches on the lower John Day and lower Deschutes (float/jet access to canyon BLM)
Species notes
Mule Deer
common opportunityA wheat-and-canyon mule deer herd managed as its own population under ODFW's 2026 herd-range system; like most Columbia Plateau herds it runs below historic numbers, and densities are modest compared to the Blue Mountains. Plenty of deer live in the breaks, and the canyon country grows an occasional heavy old buck, but expect an opportunity hunt, not a trophy destination.
- →Glass the John Day and Deschutes canyon rims and shaded side draws at first and last light; midday, still-hunt the rimrock shade where bucks bed.
- →Hunt the wheat/CRP field edges that butt against canyon breaks in the evening — deer feed up out of the canyons onto green winter wheat at dusk.
- →Use Cottonwood Canyon State Park's walk-in ground off Hwy 206 to reach lightly hunted canyon benches on foot.
- →A float or boat approach on the lower John Day reaches BLM benches road hunters never touch — but fall flows run skinny on this undammed river, so check gauges before committing.
- →Line up private permission in late summer, after wheat harvest and before seasons open — small-town relationships in Condon, Moro, and Wasco go a long way here.
Bighorn Sheep
limited trophyThe lower John Day canyon and the east bank of the lower Deschutes hold some of Oregon's healthiest California bighorn herds, and the once-in-a-lifetime canyon hunts here have produced rams in the 170-plus class. Sheep are a rare-draw bonus, but for the lucky tag holder this is among the state's premier bighorn country.
- →Scout by boat: the John Day rims from the Cottonwood Canyon reach down toward McDonald Ferry, and the Deschutes canyon above the mouth, are classic glassing water.
- →Plan on foot access from the rims or the river — vehicle access into the sheep canyons is nearly nonexistent.
- →Spend pre-season days building a ram inventory; canyon bands are localized and patternable.
Pro tips
- →Treat this as two hunts: knock-and-ask wheat-country deer on the plateau, and a public-land canyon hunt in the John Day/Deschutes breaks — plan your access strategy for one or the other, not vaguely both.
- →Cottonwood Canyon State Park is the sleeper public access: 8,000 huntable acres (outside developed zones) with rim-to-river terrain — walk a drainage away from the campground crowds.
- →Carry a current land-ownership map app everywhere; BLM parcels in the canyons are checkerboarded with private and mostly unsigned.
- →Deer densities are highest where cover meets feed — focus on the canyon-edge fields, not the open middle of the plateau.
- →If you draw a bighorn tag here, hire or borrow a boat and glass for weeks, not days — the rams live in a handful of discrete canyon pockets.
Watch out for
- !Roughly 88 percent private: a county road running through a ranch does not grant access off the road — trespass is taken seriously in this wheat country.
- !Wildfire and harvest-season restrictions can close private ground and even BLM access in the early fall — check conditions before an early-season hunt.
- !Canyon hazards are real: rattlesnakes into October, crumbling basalt rims, extreme heat early, and no cell service at river level.
- !The John Day is undammed — do not plan a fall float without checking flows; getting stuck dragging a boat for miles is a classic mistake here.
- !This hunt area is new for 2026 and does not match the old Biggs unit lines (the Biggs unit extended west of the Deschutes; this area does not) — verify the current boundary before you hunt near the Deschutes, Hwy 97, or Hwy 218 edges.
Logistics
Base along I-84 (Biggs Junction, Rufus, Arlington) for fuel and fast access, or in Condon for the heart of the area — small-town motels and cafes, limited hours. The Dalles, 20-40 minutes west of the area, has full services. Camp at Cottonwood Canyon State Park (year-round campground on the John Day) or at the Deschutes River state sites near the mouth. Fuel is sparse between towns — top off in Wasco, Moro, or Condon before dropping toward the rivers. Cell coverage is decent on the plateau and effectively zero in the canyons; roads into the breaks are gravel-to-primitive and greasy when wet.
