Harpers Corner Road is closed from the first significant snowfall some time in December to approximately Easter.
Most dirt roads in the park are clay based and impassable when wet, even with four-wheel drive vehicles including the roads to Echo Park, the Yampa Bench Road, and Island Park Road. These roads are not maintained in the winter and can be impassable due to snow.

Mormon crickets are wingless grasshoppers that swarm across roads through the summer in the western United States. These flightless insects can form such large swarms that the road appears to move and change colors where they cross.
