Colorado Parks and Wildlife is urging motorists to slow down and keep an eye out for pronghorns sheltering on the roads until the snow melts.

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

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,
