Elk Hunting in Unit 18

Unit 18 lies in Adams and Idaho counties and covers about 282 square miles. Named ground inside it runs from 1,178 to 9,352 feet. Idaho Fish and Game publishes no per-unit elk success figure we can verify for this unit. Federal land covers about 77% of it. Check land status on a current map before you plan a route.

Where to Find Elk in Unit 18

Idaho Fish and Game's material on unit 18 stops at the boundary — there is no agency account of where its elk live. The country below is verified; where to begin in it is our judgement, not the agency's. The unit lies in Adams and Idaho counties. It runs to about 282 square miles.

How Idaho Fish and Game sets up elk hunting in unit 18

Idaho Fish and Game runs its general elk seasons by elk management zone rather than unit by unit, and puts unit 18 in the Hells Canyon Zone, so the zone's tag rules are the ones that apply here.

The lines of the unit: Little Salmon River, Rapid River and Shingle Creek

Idaho Fish and Game draws unit 18 in Adams and Idaho counties on a line that runs along Little Salmon River, Rapid River, Shingle Creek and Snake River, written out corner by corner in its unit boundary descriptions. Read it as a frame, not as a hint about animals. What it does give you is the way in: the rivers and highways you cross, and the divides that decide which drainage you end up in.

High ground inside the line: He Devil, Seven Devils Mountains and Twin Imps

Named high points inside the unit include He Devil at 9,352 feet, Seven Devils Mountains at 9,347 feet, Twin Imps at 8,966 feet, Heavens Gate at 8,412 feet and Carbonate Hill at 8,128 feet. Several carry a public-land flag in our data, which makes them the first places to try for a view. Elk want timber to bed in and open ground to feed on, within a short walk of each other.

Holding ground: Cow Creek Saddle, Saw Pit Saddle and Papoose Saddle

Below them sit Cow Creek Saddle at 5,238 feet, Saw Pit Saddle at 4,954 feet, Papoose Saddle at 4,864 feet, Pipe Saddle at 4,789 feet and McCalla Basin at 4,776 feet. That is the low country of the unit — the ground animals drop into when they are pushed or when the weather turns. Pick the one with the least road on its upwind side.

Water: Bull Springs, Logged Up Springs and Mud Springs

The water inside the unit line comes to 110 mapped stream reaches, 14 lakes, 40 stock tanks and 17 springs. Named sources include Bull Springs, Logged Up Springs, Mud Springs, Thomas Spring, Horner Springs and China Spring. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.

Reading the land status

Our ownership read for this unit is approximate — it comes out as National Forest 60%, Private / Other 17%, BLM 15% and State Trust 8%, so treat it as a starting point and check a current land-status layer before you plan a route. Named ground inside unit 18 runs from 1,178 feet to 9,352 feet — more than 4,000 feet between the named features alone, so the season you draw decides which part of it you hunt.

Unit 18 terrain and land status

Measured from the unit boundary, not from the agency write-up

The lay of it

  • 2,795–7,202 ft on a terrain sample , averaging 4,894 ft ; peaks can run higher. That spread means you can hunt two seasons in one day — plan clothing for both ends.
  • 281.9 sq mi inside the boundary.

Who owns the ground

  • National Forest — 60%
  • BLM — 15%
  • State Trust — 8%
  • Private / Other — 17%

Roughly 83% is public. Carry a land-status layer anyway — these are area percentages, not a map of where the boundaries fall.

Water on the ground

  • 40 tanks
  • 17 springs
  • 110 stream segments
  • 14 lakes

Counts from mapping data, so this is how many exist, not how many hold water in a dry year. Sitting water only pays where you find fresh tracks.

Named features inside the unit

Glass from: He Devil (9,352 ft), Twin Imps (8,966 ft), Heavens Gate (8,412 ft), Carbonate Hill (8,128 ft)

Holding ground: Stevens Saddle (7,464 ft), The Narrows (7,341 ft), Bull Springs, Logged Up Springs, Mud Springs

Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.

Idaho Fish and Game's 2025 first drawing for elk in unit 18, with residents and nonresidents kept apart because they draw from different tag pools:

  • Hunt 2002 — residents 613 applicants for 72 tags, 12% drawn; nonresidents 179 applicants for 8 tags, 4% drawn
  • Hunt 2121 — residents 230 applicants for 36 tags, 16% drawn; nonresidents 121 applicants for 4 tags, 3% drawn
  • Hunt 2056 — residents 203 applicants for 135 tags, 67% drawn; nonresidents 27 applicants for 15 tags, 56% drawn

Idaho draws at random with no point system, so these are what that year happened to look like, not a requirement to build toward. Idaho Fish and Game reuses hunt numbers for different areas between years, so the figures are matched on the area each hunt had in 2025.
