This picture is from Wyoming SR 70 somewhere between miles 25.0 & 42.1.
Bruce Burrows, from the Wyoming Department of transportation, and his on-site engineers in the area have granted permission for cyclists to walk around the landslide on State Route 70. The engineers seem to be confident that racing and touring mtb'rs are savy enough to get around it. He did stress to use caution. Also, there could be people/heavy equipment working in the area.
This might change later in the summer when they start working on the road. Here is number to contact for more info:
Wyoming Department of Transportation - 307.777.4375
Again, the Wyoming Department of Transport has granted permission for cyclists to walk around the landslide
