You're correct, they will just keep moving until they either find open forage, pile up against an impenatrable barrier, or die in place. We had a tough winter two years ago (not quite so tough as this one) and the goats migrated into town and then just started dropping. 60-70 carcasses on the golf course in the spring. Several had been collared around Med Bow as part of a migration/habitat study, so we know they had made it that far before they died. It's damned tough to see, and we're reliving it this year. The next year quotas were cut in 47, year after that 46 was severely reduced (probably a year too late imo.) Quota in 47 was increased again last year, I hope it's drastically cut this season.Antelope on the area migrate great distances. They don't have to go far to reach more open country.
