Castle Peak in the Elk Mtns has 2345 feet of prominence according to peakbagger.
How is Ohio? I don't miss it at all, I'm enjoying being back out west finally again. I used Peaklist.org for the prominence on this list. http://www.peaklist.org/USlists/COP2000.html That had Castle listed as 2365. I've found that Peakbagger and Peaklist use different methods for Prominence.
