Overview

GMU 102 covers a big block of Washington/Yuma County plains straddling the Arikaree River, a patchwork of irrigated and dryland crops, CRP, and sandsage prairie. It's a productive deer unit — mule deer on the grass breaks and crop edges, whitetails in the cottonwood bottoms — paired with pronghorn that post notably good success on the open shortgrass. Elk are only rare plains drifters. As with the rest of the northeast corner, the country holds game but is almost entirely private, so access defines the hunt.

Terrain

Rolling high plains with the shallow Arikaree River corridor cutting through; broad open horizons and sandy soils.

Cover: Sandsage and shortgrass prairie, dryland wheat/corn/milo, center-pivot irrigation, CRP grass, and cottonwood/willow bottoms along the Arikaree.

Landmarks: Arikaree River · Wray · Vernon · Kirk

Access

Predominantly private agricultural and ranch land. Colorado State Trust Lands are NOT huntable unless enrolled in CPW's Public Access Program, so the trust checkerboard should not be counted as open. Practical public access is limited to CPW Walk-In Access leases and any small State Wildlife Areas; otherwise landowner permission or a lease is required.

Managers: private ranch, private farm, Colorado State Trust Land (access-restricted), CPW Walk-In Access

Species notes

Mule Deer

common quality

The unit's headline tag with the highest deer harvest of this cluster. Bucks work sandsage draws, grass breaks, and the edges of crop circles; limited-draw with good-quality mature deer available on the right ground.

  • Glass sandsage and CRP draws at dawn and dusk
  • Pattern deer moving between grass bedding and crop fields
  • Concentrate on secured private or Walk-In ground

Whitetail Deer

common quality

Whitetails hold the Arikaree bottoms, shelterbelts, and riparian brush, mixing with mule deer at field edges — a true eastern-plains whitetail hunt.

  • Hunt cottonwood bottoms and shelterbelt travel corridors
  • Set on field-to-cover routes at first/last light
  • Rut hunts in the river bottoms pay off

Pronghorn

common quality

Antelope success here runs higher than most of the cluster. They range the open sandsage and shortgrass; tags are limited-draw and access-dependent.

  • Glass big open flats and fallow ground
  • Use draws, windmills, and terrain folds to stalk
  • Ambush water in hot early seasons

Rocky Mountain Elk

transient low

Elk are incidental — the occasional plains wanderer, not a resident herd. Minimal harvest.

  • Not a target species; treat encounters as opportunistic

Pro tips

  • Nail down landowner permission or a lease well ahead — access is everything here
  • Check the current Walk-In Access atlas each year; parcels rotate
  • Whitetails in the Arikaree bottoms; mule deer and antelope on the open sandsage breaks
  • Skip State Trust sections unless they're enrolled in the Public Access Program

Watch out for

  • !Almost entirely private — verify boundaries and avoid trespass
  • !State Trust Lands closed to hunting unless in CPW's Public Access Program
  • !Clay roads become impassable when wet
  • !Standing crops conceal deer until harvest

Logistics

Wray is the main hub for fuel, lodging, and supplies, with Yuma to the northwest. Travel is on a graded county-road grid, 2WD-friendly outside of wet weather when clay roads slick up. Cell service is reasonable along highways and near town.
