Contiguous United States 4,000+ Foot Prominence Completion Maps

Description

This page is an index to cell-based completion maps for the 4,000+ foot prominences of the 48 contiguous United States. There are 147 peaks on the resulting map with a mean ("interpolated") prominence of at least 4,000 feet. Mount Ritter in California with a mean prominece of 3,990 feet is also displayed on the map since its optimistic prominence is 4,023 feet.

Five of the 147 summits lie in the "error range" wherein their clean prominence falls short of 4,000 feet - Tin Mountain (CA), Toro Peak (CA), Chpaaqn Peak - also called "Squaw Peak" (MT), Holland Peak (MT), and North Gardner Mountain (WA).

All but five peaks lie in the western United States - Mounts Mitchell and Washington (both ultra summits), Mount Marcy, Clingmans Dome, and Katahdin.

The baseline completion map portrays prominence cells for these summits.
The following individuals contributed to its formation -

Andy Martin, Edward Earl, Aaron Maizlish, Greg Slayden, John Kirk, Jerry Brekhus, Steve Fry, Jeff Howbert, John Roper, David Olson, Ken Jones, Paul Klenke, Ryan Schilling, Dan Robbins, and John Vitz compiled various national and statewide prominence lists.

Eric Noel created the baseline cell map.

Detailed information for these 4,000+ foot prominences is available at peakbagger.com. There one finds the clean, mean, and optimistic prominences for the 142 peaks with at least 4,000 foot of clean prominence.

Coloring and Interpreting a Completion Map

The same colors and similar rules for their use apply as for painting a county highpoints completion map.

Personalized color schemes are acceptable provided that a legend explains the meaning of each color.

The following facts enable correct coloring of eastern prominence cells -

Katahdin (Maine) is in the Mount Washington ultra cell.

Clingmans Dome is in the Mount Mitchell ultra cell.

Mount Marcy is also in the Mount Mitchell ultra cell.
Mount Washington is in New Hampshire, and its saddle is near Albany, New York. The Mitchell/Washington cell boundary proceeds north to Lake Champlain and finally into the Saint Lawrence River - and also south into the Hudson River. Situated in New York, Mount Marcy lies west of that line and hence is in the Mount Mitchell cell.

The following facts enable correct determination of one's yellow ("home") glob
as distinct from one's remaining cells (painted blue).

The Mount Cleveland and Gannett Peak cells meet just a few miles into North Dakota.
The Gannett Peak and Pikes Peak cells meet at the junction of the two forks of the Platte River.
The Mount Cleveland and Pikes Peak cells meet at the outlet of the Platte River near Omaha.

The Sierra Blanca and Mount Elbert cells meet a few miles into Texas.

The Mount Mitchell cell borders the Mount Cleveland, Pikes Peak, Blanca Peak, and Mount Washington cells.
The Mount Washington cell borders the Mount Mitchell AND Mount Cleveland cells.

The Miller Peak and San Gorgonio cells meet at the Colorado River delta.
The Miller Peak and San Jacinto cells meet at the Colorado River delta.
