The Sacramentos can be divided into two sections: a main, northern section, encompassing most of the land area and all of the terrain above , and a smaller southeastern section, contiguous with the
Guadalupe Mountains. Neighboring ranges and landforms include the
Tularosa Basin, immediately to the west of the main section of the range;
Sierra Blanca and the
Capitan Mountains to the northwest and northeast; the Border Hills and the western edge of the broad
Pecos River valley to the east; the Guadalupe Mountains to the southeast; and
Otero Mesa, which lies south of the main section and southwest of the southeastern section. The
Rio Tularosa and the
Rio Ruidoso (and hence
U.S. Route 70) separate the Sacramentos from Sierra Blanca and the Capitan Mountains. Located at the foothills of the Guadalupe Mountains is
Carlsbad Caverns National Park, a series of caverns scattered throughout rugged terrain. The western edge of the main section of the Sacramento Mountains forms a series of dramatic
escarpments leading up to a high ridge, which includes the highest named point in the range,
Cathey Peak, 9,645 feet (2,940 m). From this ridge the mountains slope gently down to the east, merging gradually into the Pecos Slope to the west of
Artesia. There are actually two unnamed highpoints of the range, both approx 9,695 ft. One is near Sunspot above Corral Canyon and FR 64. The second highpoint is on the crest of Benson Ridge. ==Geology==
