I have uploaded an unpublished essay entitled Prominence and Orometrics that I wrote in 2003.  This should serve as an introduction to the concepts and usefulness of important concepts such as prominence, key saddles, divide trees, mountain lineage and parents, and domains.  Please send feedback to the author.
