Guide to North American Meteorites displays the locations of 1250 meteorite incidences in the continental USA, Mexcio, and Southern Canada. The dimensions are 1 m (39 in) x .7m (27.5 in). The map also displays ecoregions which shows a striking pattern of meteorite finds in Texas, New Mexico, Kansas, and Colorado in the steppe (high dry plains). The data plotted on the "Guide to North American Meteorites" include those meteorites published in the British Museum's Catalogue of Meteorites, 4th edition (1985) and subsequent Meteoritical Bulletins through 1999.
The map is a tutorial and guide to locations where meteorites are more likely exposed on the surface. Even though several tons of meteorites fall onto the Earths surface daily, less than 1 % of that makes it to the surface as recoverable mass. Meteorites erode at differing rates depending on the type of meteorite and the ecoregion of the fall. These conditions make meteorites more rare than gold, and often times more valuable.
