List Description

To be on this list, a peak must be the triple divide point of three basins of rivers that reach marine water, and the smallest of these basins must have an area of over 1500 square miles. This last condition excludes what could easily be hundreds of peaks that are triple divides that involve small rivers and tiny coastal creeks.

Also, this list only shows triple divide points for rivers that enter the ocean directly (or for well-defined internal drainages). Therefore, the entire Mississippi-Missouri-Ohio system is considered one basin, and triple divides that include two or three components of this system (e.g. the Colorado-Arkansas-Platte triple divide, where the Arkansas and Platte are both Mississippi tributaries) are not shown. This does leave out a large number of points in the central part of the United States, but most of these points would be low hills in relatively flat country.
