Where to Find Mountain Goat in Unit G10
CPW's material on unit G10 stops at the boundary — there is no agency account of where its mountain goat live. Every place named below sits inside the unit line. Which of them holds animals in your season is for you to find out. The unit lies in Summit, Park and Lake counties.
The lines of the unit: Colo. 9, Boreas Pass Rd. (USFS 404 and Summit CR 10)
CPW has unit G10 bounded on the north by I-70; on the east by Colo. 9 and Boreas Pass Rd. (USFS 404 and Summit CR 10); on the south by Continental Divide, Colo. 9, Scott Gulch, Middle Fork of South Platte River and Platte Gulch to Lake-Park Co. line; on the west by Lake-Park Co. line, Continental Divide, Colo. 91 and I-70. Read it as a frame, not as a hint about animals. Those features are what you will check against the map all week, and the divides among them are the ones that matter.
High ground inside the line: Tenmile Range, Quandary Peak and Fletcher Mountain
Named high points inside the unit include Tenmile Range at 14,263 feet, Quandary Peak at 14,243 feet, Fletcher Mountain at 13,936 feet, Pacific Peak at 13,930 feet and Crystal Peak at 13,853 feet. Several carry a public-land flag in our data, which makes them the first places to try for a view. Goats live above the trees on cliff and talus and come down only when weather makes them.
Holding ground: Putnam Gulch, McCullough Gulch and Fredonia Gulch
Below them sit Putnam Gulch at 10,669 feet, McCullough Gulch at 10,283 feet, Fredonia Gulch at 10,261 feet, Dry Gulch at 10,024 feet and Carter Gulch at 9,944 feet. These are the folds worth watching, and the ones other hunters walk past on the way to somewhere steeper. Pick the one with the least road on its upwind side.
Water: Blue Rock Spring and Iron Springs
Named sources include Blue Rock Spring and Iron Springs. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.
The herd this unit belongs to: MG-07
CPW does not manage mountain goat unit by unit. It manages them as data analysis unit MG-07, and unit G10 is one piece of it. The rest of MG-07 is unit G7, unit G15 and unit G16. Read a neighbour in the same herd before you read the state average — the herd, not the unit line, is what the agency is steering.

How to Hunt Mountain Goat in Unit G10
Mountain Goat Success Rates
CPW's 2023 harvest estimates put mountain goat success in unit G10 at 92% — 24 animals taken by 26 hunters. The hunter count is large enough for the percentage to mean something and small enough that a good or bad year still moves it.
These are the agency's own printed figures for this unit, not a modelled estimate and not a state average. They describe one season, so check CPW's current harvest estimates before you read a trend into them.

Open in Draw Odds EngineCPW's 2026 draw recap for mountain goat in unit G10, by hunt code, with resident and nonresident kept apart because the two draw from different licence pools:
- GEG10O3R — Rifle, 3rd Season, Either Sex, nonresident: 630 applicants for 1 licences, 0.2% drawn, 3 preference points needed
- GEG10O1R — Rifle, 1st Season, Either Sex, resident: 294 applicants for 4 licences, 1.4% drawn, 3 preference points needed
- GEG10O3R — Rifle, 3rd Season, Either Sex, resident: 209 applicants for 3 licences, 1.4% drawn, 3 preference points needed
- GEG10O2R — Rifle, 2nd Season, Either Sex, resident: 205 applicants for 4 licences, 2% drawn, 3 preference points needed
Colorado runs a pure preference-point draw, so the point figure above is the requirement the agency published for that code in that year, not a forecast for the next one. There are 7 further code-and-residency combinations in the recap for this unit. Figures checked against CPW's own statistics pages on 2026-06-09.
