Including the river bottoms and sloughs along the Snake River from the Ririe area to Roberts and down to Idaho Falls, this small unit is mostly managed for whitetail deer. Mule deer and elk are also hunted here.

Most whitetails are taken on private land, which comprises the majority of the unit.

Flat, heavily wooded river bottoms, sloughs and canals run through private agricultural land. The northwestern corner is sagebrush-covered high desert. Elevations range from roughly 4,500 feet to the top of the North Menan Butte at 5,619 feet.

Waterways surrounded by tall cottonwood trees and thick willows run through private alfalfa, corn and grain fields. The northwestern corner is sagebrush-covered high desert with exposed lava rock. Public marshes have cattails and bulrushes.

Hunters need permission from landowners to hunt the vast majority of the unit. Exceptions include a strip of BLM land along the Snake River from Ririe to Roberts, some BLM acreage in the northwest corner and three public marshes — Deer Parks, Cartier Slough and Market Lake wildlife management areas. All are walk-in hunting areas that get heavy public pressure. Many roads branch off Highways 26, 20, 33 and 48. Travel is easy, and most roads are paved with the exception of primitive roads on BLM land, where hunters need ATVs or four-wheel-drive vehicles.

Hotels and motels are in Idaho Falls, Rigby and Rexburg. RV camping is available at Jefferson County Lake Park in Rigby, Mountain River Ranch in Heise, Rainbow Lake in Rexburg and Thompson RV Park in Rexburg. Camping is allowed on most BLM land, but camp trailers and RVs are not recommended here.
