Here's an idea for a new list that expands upon the CoHP list. Do all the peripheral peaks on the county borderline.
For example, in CO, I believe there are 395 ranked peaks on the border of 2 counties, and 3 peaks on a 3-Co line. Thus the list would be 398 peaks, but count as 799 summits (395x2 + 3x3) when you tally up the county peaks logged.
Pretty efficient climbing!
I wonder if anyone has completed them all?
Likewise, there are 126 unranked peaks on a 2-Co line, and none on a 3-Co line (listed that is).
Would be nice to list all 3-Co and the only two 4-Co pts in CO, even if unranked ;)
Think of it this way, this pt would be the highest pt you could bag common to 3 or 4 Co lines!
