This is from the top of Cicero Peak. The temperature drop was about10-15 degrees in the short 2,000 altitude climb so it was actually pleasant up top.
In one of the photos you can see South Dakota, Wyoming, and Nebraska. Some people claim you can see North Dakota, but I highly doubt that.
I strongly recommend hiking and mountain climbing in the Black Hills simply because you can actually climb a "mountain" within a day and not have to worry about altitude sickness or freezing temperatures.
