Can't say that I've ever hunted bears in Colorado, but I have to assume their habits are similar to our Wyoming bears. Just from my own personal experience, here's what I'd throw out there. I'm not a bear biologist, so I could be totally out to lunch on all of this, but I do manage to kill bears.
They eat a lot the ENTIRE season, not just in the fall; they start "putting on fat for the winter" as soon as they wake up in the spring. That means you need to find a food source.
They drink a lot of water, so you need to find a water source. Could be very small, but I really think they prefer clean water.
Most (um, all) of the dens that I have located have been in the nastiest, rockiest, most blown-down, steepest, north-facing slopes you can imagine. Find a few of those areas.
Bears do roam a bit, but really not much compared to other big game. Find all three of the items above, and you'll be getting into bears.
Last point: there's a big difference between finding a spot where bears are likely to be and finding a spot where you'll be able to kill one. In any sort of thick cover, you'll almost never be able to get the drop on one. Try to find an area where they have to cross a meadow, avalanche slide, or open south-facing slope in order to move between food/water/shelter, and you'll be in business.
Last last point: in some areas, the bears are almost entirely nocturnal, so there's going to be a bit of luck involved, or at the very least, plan on taking a shot right at last light.
Good luck and good hunting.
