Deep, crusty snow piled up on fields in eastern Colorado after last week’s snowstorm is driving herds of pronghorn onto roads, and dozens of them are dying, state wildlife officials said. Pronghorn are being hit by drivers in droves as they seek refuge from snow-covered fields,

That included 53 being killed on Nov. 12 along U.S. Highway 36 east of Byers, according to Colorado Parks and Wildlife.

More than 100 pronghorn have died on Eastern Colorado roadways as winter descends upon the region, according to state wildlife officials. Warning: This video contains graphic content. Viewer discretion is advised.
