Reviewed 2007 by John Kirk and 2010 by Edward Earl. ¹ The Valley county HP rivals a 3300 to 3325 area in Canada. If the Canadian hill wins, the Valley county HP saddle is instead a large area around 49.115°N 106.513°W, a large area around 49.068°N 106.516°W, or at 49.050°N 106.512°W. All of these possible saddles have elevation in the 2925 to 2950 contour interval, which would lower the prominence of the Valley county HP by 25 feet. ² Pike Creek Hills sprawls across the border between Petroleum and Fergus counties. If its HP is in Fergus county, the HP of the Petroleum part gets the low-prominence saddle listed, and it has no chance of being the Petroleum county prom champ. ¹ The prominence saddle for Highwood Baldy has been cut by a RR grade and lowered by 1 contour. It is unclear whether the pre-RR saddle was above or below the 4340 contour. ² Pike Creek Hills sprawls across the border between Petroleum and Fergus counties. If its HP is in Fergus county, the HP of the Petroleum part gets the low-prominence saddle listed, and it has no chance of being the Petroleum county prom champ.
