List "CO County Prominence Points (Mountains)" By bdloftin
Notes: Most prominent point in each western/mountain county. Some ranked and unranked eastern county prominence points are in LoJ. However, some of the eastern county prominence points are both unnamed and unranked and are not in LoJ. Also, there are multiple contenders for some counties, making it hard to list just a single point.
See peakbagger's list for the eastern counties.
