Northwest New Mexico exemplifies the spirit of New Mexico's motto of the "Land of Enchantment." The landscape is diverse from steep canyons to rolling badlands throughout the San Juan and Rio Arriba counties. The vast network of canyons offer many opportunities to explore and discover the natural and cultural wonders.

To date more than 400 natural arches have been documented in San Juan County alone. What is a natural arch? As defined by the Natural Arch and Bridge Society (NABS), "a natural arch is a rock exposure that has a hole completely through it formed by the natural, selective removal of rock, leaving a relatively intact frame." To learn more about natural arches, please visit the NABS website.

For purposes of classification, the arches have been classified on the following Metric Attibutes as established by NABS:
Miniature = all opening dimensions are smaller than 1 meter (3.28 feet).
Minor = one or more opening dimensions are at least 1 meter (3.28 feet).
Significant = the product of any two orthogonal opening dimensions is at least 10 square meters (107.64 sq ft).
Major = having a span of 50 meters or more (164 feet).
To help the outdoor adventurers' exploration, the area has been divided into three regions. Click on the links to explore the canyons in each of these regions. Each region will have specific canyon tours, maps and other arch information.
