The Pyramid Mountains are a moderate altitude, north–south trending mountain range at the north of two valleys that also are north–south, and extensive, as the Continental Divide traverses due south through the ridgeline to enter northwest Chihuahua state, Mexico.

The range consists of a north and south portions separated by a lower elevation pass (1,430 metres (4,690 ft)) between Jose Placencia Canyon on the west and Muir Draw on the east.

[1] North:[1] South:[1] The Continental Divide starts to leave the forested mountain regions as it goes southwest from Silver City.

It passes from the southern Little Burro Mountains, crosses the Big Burro's, then on a circuitous route after skirting the northeast of the Cedar Mountain Range, it passes across the water divide of the north Playas Valley, west of Hachita.

It finally enters a series of north–south ranges, including the Animas Mountains, and traverses south into northwest Chihuahua, Mexico.
