Elk Rut in Colorado

[petey]

Bulls will start bugling around 1st week of archery (about 1st of Sept) depending on if it's still 80 degrees or not and they should still be bugling for at least another 10 more days from today. First rifle season they are still pretty hot, but as grayghost said...they tend to shut up in a hurry after even the 1st season. All depends on pressure and weather.

I'd say prime time is the last couple weeks of Sept - first couple weeks of Oct.

I've called big bulls in as early as Labor Day weekend in the Route National Forest North of Craig (probably where you're talking about?)
