Volcanic Landforms
... If a volcano’s lava has high viscosity, the lava may explode into the air and harden into ash, cinders, and bombs. These materials pile up around the vent, forming a steep, cone-shaped hill or mountain called a cinder cone. Sometimes lava flows alternate with explosive eruptions of ash, cinders, and ...

Potrillo volcanic field
The Potrillo volcanic field is a monogenetic volcanic field located on the Rio Grande Rift, in a portion of its rift valley, in southern New Mexico, United States and northern Chihuahua, Mexico. The volcanic field lies 22 miles (35 km) southwest of Las Cruces, New Mexico.
