List "Howbert List-Oregon Top 100 (500 ft. prom)" By Swithich
Notes: List includes nine extras beyond the Howbert List (probably due to unknown heights and the use of clean prominence).
Extra nine are #:
22-Craig Mountain;
25-9180;
31-Traverse Ridge;
50-8721;
58-Jackson Peak;
65-8500;
69-8428;
85-8140;
90-8100.
Consider all do not meet clean prominence requirements (assuming the summit was unknown on older maps).
List is probably best described as "Howbert + 9" since the list has been around since 1996.
