These animals have a limited migration and the herds sometimes number well over 200 individuals. When a large herd starts crossing a road, motorists have been known to need to wait for over an hour for the entire herd to cross, prior to being able to drive on. This is a large species of deer and a weight of 700 pounds isn’t uncommon. They are also surprisingly tall at the shoulder; over five feet.
Probably one of the reasons the Elk Foundation calls Montana home.
You’re probably right. Montana has the most migratory elk in the US.
