Red Hill volcanic field

Red Hill volcanic field, also known as the Quemado volcanic field, is a broad monogenetic volcanic landscape in western New Mexico near Red Hill and around Zuñi Salt Lake. Rather than a single mountain, it is a field of more than 40 vents, including scoria cones and silicic dome fields, that produced basaltic lava flows. It forms part of the Jemez Lineament, a chain of relatively young volcanic fields across Arizona and New Mexico. Volcanism occurred in two main pulses, with older eruptions in a narrow trend and later activity spreading more widely. Its best-known feature, Quemado crater, preserves clear evidence of collapse and explosive eruption.
