I hunted several years ago in the Colorado Flat Tops and there was a big fire right where I usually hunt. They wouldn't let us in there in July to scout. Didn't seem to effect the animals come elk season the first week in September. There was so much smoke during bow season that you couldn't glass anything. We would be walking by trees that had smoke rising out of the base of them. Sometimes we found elk bedded in the ashes. I was worried some days that the fire would start back up and we would be running for our lives. We had backpacked in 3 miles. Shot a cow several days into the hunt and saw the usual amount of elk and rutting activity. It wasn't torched to the ground in most places but still burning everywhere. There was a lot of evidence of caterpillars opening a road up to get the fire fighters in but they were long gone.
