A small volcanic cone made entirely of pyroclastic material is called a cinder cone volcano.

The type of volcano that is built entirely of ejected lava fragments is a volcanic cone. Volcanic cones can be of varying types, and it depends upon the nature, and size of the fragments ejected during the eruption.
The volcanic type that typically produces small steep-sided structures composed of pyroclastic material is a cinder cone. Cinder cones are formed from explosive eruptions that eject particles of volcanic ash, cinders, and bombs into the air. These materials fall back to the ground and build up around the vent, forming the characteristic steep slopes of cinder cones.
Flood basalts build volcanic cones because flood basalts are believed to originate when the head of a mantle hotspot first arrives beneath the base of a plate. Because of this, they are unable to build volcanic cones.
They are just dormant
Once a part of an ancient interior sea, the desert was formed by volcanic action (lava surfaces with cinder cones are present) and by material deposited by the Colorado River.

The three volcanoes names are Shera, Kibo and Mawenzi
Mt Fuji is a composite volcano, or stratovolcano. Composite volcanos are typically large, steep-sided, symmetrical cones that can continue to grow in height by adding layers of various volcanic material.
Cinder Cones
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
