The complete county distribution, spread across 19 Montana counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Mountain lions hold territories that can stretch over a hundred square miles, and Montana’s rugged mix of mountain and breaks country, Glacier National Park, the Upper Missouri River Breaks National Monument, and Custer-Gallatin National Forest, gives this solitary cat the elevation range and cover it needs to hunt deer and elk largely undetected.

Records spike sharply in September, more than four times the summer low, a pattern that likely tracks increased hunter and hiker traffic during archery and early rifle seasons more than any true change in lion movement, since this is a year-round resident rather than a seasonal visitor. NatureServe rates the species secure (S5) in Montana, and most confirmed sightings still come from tracks, kill sites, or trail cameras rather than a direct encounter with an animal built to avoid exactly that.
