Those are "midwestern mountains."
When I was a teeneager, I learned to ski in Pennsylvania. After going skiing 7 or 8 times I could go down the expert hill without much difficulty. The next year I moved out west. My new friends were (real) skiiers. They invited me skiiing after I told them I knew how. About half way up the lift I knew I was in big trouble. I got off the chair and wobbled over to the edge and looked down into ...oblivion. That's when I realized what a mountain really was.
