A lot of folks talk about mountain lions like they’re a “back then” animal — something your granddad warned you about, not something you might bump into on a trail today. The reality is they’re still very much around in big chunks of the West and Southwest, and several states manage them as established, breeding big-game populations. You don’t have to see one to be sharing country with them, either. Most sightings happen because people moved deeper into lion habitat, prey animals moved with them, and lions did what lions do: stayed quiet and kept living where the groceries are.
I’m not saying you should panic every time you see a deer trail behind your house. I am saying it’s worth getting the picture straight. In the states below, wildlife agencies openly describe lions as common/thriving, set seasons, track harvest, and publish management info — which is the opposite of “they’re gone.”
Colorado
Colorado is one of the clearest examples that lions aren’t a rumor. Colorado Parks and Wildlife puts the projected statewide population of independent lions around 3,800–4,400. That’s a real, managed population, and CPW has been doing more work to test modeled estimates with on-the-ground studies in different areas. If you hunt or hike Colorado long enough, you don’t have to go looking for lion sign — you’ll eventually find it.
Utah
Utah treats cougars like a serious, managed predator, and they publish annual harvest reporting. In the 2024 cougar annual report (covering Nov. 1, 2023 to Oct. 31, 2024), Utah’s DWR notes 530 cougars harvested by hunters in that period, plus additional removals and other mortalities. That kind of reporting exists because lions are present statewide enough to require structured management, season frameworks, and conflict response.
Arizona
Arizona is another state where the “they’re gone” talk doesn’t survive contact with reality. Arizona Game & Fish describes mountain lions as common and gives an estimated abundance of about 3,000 in the state. If you spend time in the desert hills, higher country, or that rough transition zone where neighborhoods push up into wild ground, Arizona is one of the places you’re most likely to hear about sightings — even if you never see one yourself.
New Mexico
New Mexico Game & Fish spells out that it runs a statewide cougar management program and uses management zones with estimates based on habitat, prey, and other factors. That’s the point people miss: in places like New Mexico, lions aren’t “passing through.” They’re part of the landscape, and the state treats them that way — including targeted work in certain areas (like bighorn ranges) where conflicts matter.
Nevada
Nevada is big, dry, rugged, and a whole lot of it is perfect lion country. Nevada wildlife reporting shows lion work tied to predation management efforts in specific ranges and units, which again is what you do when lions are present and interacting with prey and people. Nevada doesn’t have the same “everyone sees one” reputation as some states, but don’t confuse that with absence. Lions don’t need to be common in town to be established on the landscape.
Montana
Montana Fish, Wildlife & Parks is pretty blunt about it: mountain lions are thriving and have reoccupied their historic statewide range. Montana also publishes density monitoring reports in certain areas using modern methods (DNA sampling) to estimate density. If you’re calling lions “gone” in Montana, you’re basically ignoring what the state’s own wildlife managers are saying.
Wyoming
Wyoming’s a good reminder that “no official statewide population estimate” does not mean “no lions.” Wyoming Game and Fish describes lions as found statewide but rarely seen, which is exactly how this animal operates. They also publish harvest/mortality information; for example, one WGFD publication notes 354 mountain lions harvested during the 2024–2025 season. When a state is tracking harvest at that level, you’re not talking about a ghost species.
Idaho
Idaho is loaded with lion habitat, and Idaho Fish and Game has an active Mountain Lion Management Plan (2024–2029) discussing distribution, conflict trends, and management direction. Idaho’s the kind of place where lions can be present in serious numbers in big country and still feel “invisible” to most people. That invisibility is the cougar’s whole survival strategy — until it isn’t, and you’ve got a depredation call or a trail-camera surprise.
