I'm not aware of a gost town by Pikes Peak.There is one close to the Royal gorge but I dont think you can see that from Colorado Springs.
I have seen a small remains of a town I think it might have been in the Cheyenne Canyon (not sure on this)just south west of Colorado springs,but some of the buildings looked like they were still in use.
The one close to the Royal Gorge,some of the buildings were relocated to that spot,and they are used for some movie sets.
