Rock springs wy. to Thermopolis wy. then onto Cody

That is correct. The down grade into Lander is actually steeper. In the winter months down hill into Lander has ice and gets dangerous. In the summer no problems except the WY wind on occassion. I always check wind before going over that pass. I drive it 5 or 6 times a year winter and summer.Only easy way to go south from nw WY. I think I have a winter photo going down into Lander. I'll post if I can find it.
