Which desert in northern Mexico contains the Pinacate volcanic field?

The desert in northern Mexico containing the Pinacate volcanic field is the Sonoran Desert.

The Pinacate volcanic field lies in northwestern Sonora, near the head of the Gulf of California. It is part of the El Pinacate and Gran Desierto de Altar Biosphere Reserve, a protected landscape that UNESCO designated a World Heritage Site in 2013.

The field includes the Pinacate Peaks, a shield volcano, hundreds of cinder cones, lava flows, and several large maar craters formed when rising magma interacted explosively with groundwater. The surrounding Gran Desierto de Altar contains extensive active sand dunes and is a distinctive sub-region of the larger Sonoran Desert.

A common mix-up is to answer Gran Desierto de Altar. That name identifies the local sand-sea sub-region, while Sonoran Desert is the broader desert classification asked for here. The nearby Colorado, Chihuahuan, and Mojave deserts are separate North American desert regions.
