Bison buffalo drivers in South Dakota

Travelers driving through the Black Hills area of South Dakota ran into a roving roadblock this week: a herd of bison set up on the snowy pavement, and it could be because they were hungry.

Frank Carroll sent this video of the herd near Wind Cave. Carroll says that herds have been popping up on roadways more frequently since a fire tore through the area in December.

The bison have little food left to forage after the fire, so they’ve taken to eating grass that pops through the snow near roadways and licking salt that’s laid down on roads for traction.
