Elk Mountain stands out south of I-80, east of Rawlins. This stretch of the highway is reknown for snowing over. The state has installed miles of snow fences in an attempt to reduce the amount of snowfall drifting onto the highway, with only small effect apparently.
With the tailwind as I head east, I’m getting great mileage – almost 50 mpg. Road conditions are pretty good. The signage warns of “slick spots”, but have not seen anything serious (yet).
