Okay, I'll go out on a limb and take a guess. I know what bobcat cover looks like in California, Baja California, Sonora, New Mexico, Arizona, Colorado, Wyoming, Texas, Utah, Nevada, Washington, (eastern) Oregon, (eastern) and Idaho....and brief sojourns in a couple others....not Montana.
I suspect you have more cats than you are aware of. I can't think of a good reason why they wouldn't be in the same places in Montana as in (basically) every other western state? The best hint I could give you is that bobcats like elevation, but not always. Look up in the rimrock, canyons, foothills, whatever you call them locally. They don't spend a lot of time in the flats, but every once in a while, they do; usually in summer.
If you know what to look for, they are relativly easy to locate. An experienced (cat) hunter could find (at least a few) bobcat in your area in about two days.
Good hunting. LB
