Where to Find Rocky Mountain Bighorn Sheep in Hunt Area 27-1
Idaho Fish and Game draws an exact line around hunt area 27-1 and says nothing about where the Rocky Mountain bighorn sheep stand inside it. The country below is verified; where to begin in it is our judgement, not the agency's.
What hunt area 27-1 is
Idaho Fish and Game describes Rocky Mountain bighorn sheep hunt area 27-1 as that portion of Unit 27 west of the Middle Fork of the Salmon River upstream from the Big Creek drainage to and including the Indian Creek drainage. That makes it a piece of ground drawn for this hunt, not a unit, and the outline on this page is IDFG's own polygon for it rather than a unit outline. The units it is drawn from lie in Custer, Lemhi and Valley counties.
High ground inside the line: Big Baldy, Big Baldy Ridge and Mormon Mountain
Named high points inside the hunt area include Big Baldy at 9,699 feet, Big Baldy Ridge at 9,699 feet, Mormon Mountain at 9,511 feet, Red Peak at 9,460 feet and Red Ridge at 9,444 feet. Several carry a public-land flag in our data, which makes them the first places to try for a view. Sheep need rock to escape into and will not stand far from it.
Holding ground: Sammy Gulch, Kiwah Meadow and Cow Basin
Below them sit Sammy Gulch at 3,481 feet, Kiwah Meadow at 6,062 feet, Cow Basin at 5,407 feet, Aquinaldo Flat at 4,641 feet and Countess Gulch at 4,360 feet. Those are the basins, parks and bottoms this hunt area has, and they are what you glass into from above. Work out which of them you can see from one position before you pick a camp.
Water: Hospital Hot Spring, Kwiskwis Hot Spring and Cox Hot Springs
Named sources include Hospital Hot Spring, Kwiskwis Hot Spring, Cox Hot Springs and Sunflower Hot Springs. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.
How high the named ground goes
Named ground inside hunt area 27-1 runs from 3,481 feet to 9,699 feet — more than 4,000 feet between the named features alone, so the season you draw decides which part of it you hunt.

Holding ground: Kiwah Meadow (6,062 ft), Cow Basin (5,407 ft), Aquinaldo Flat (4,641 ft), Hospital Hot Spring, Kwiskwis Hot Spring
Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.
How to Hunt Rocky Mountain Bighorn Sheep in Hunt Area 27-1
Rocky Mountain Bighorn Sheep Success Rates
Idaho Fish and Game's per-unit harvest statistics describe general seasons on game management units, and hunt area 27-1 is a controlled-hunt area, not a unit, so there is no figure here we can tie to it. A unit's general-season number would describe different hunters on different ground. Idaho Fish and Game's hunt planner reports controlled-hunt results hunt by hunt, which is the figure to check before you apply.
