According to Colorado Parks and Wildlife, the herd likely congregated on the highway because of drifting snow on the ground and in the fields.

CPW said more than 100 pronghorn – including 52 on US 36 near Byers – have been killed on Eastern Plains roadways since a snowy stretch dumped as much as 40 inches in some spots.

Colorado Parks and Wildlife is asking drivers to watch out after over 100 pronghorns were found dead on roads across eastern Colorado.
