Blocky lava flows from near Miller Knoll reach nearly to Panguitch Lake in the distance to the NE. Lava flows from the same vent traveled down Black Rock Valley to the SE. This extensive lava field is one of the youngest of the Markagunt Plateau volcanic field.

Blocky unvegetated lava flows known as the Black Rock Desert extend from near Miller Knoll to the SE. These flows, which also extend NE to near Panguitch Lake, are among the youngest features of the Markagunt Plateau volcanic field. This is one of several young volcanic fields in SW Utah.

The thick blocky lava flow in the background near Panguitch Lake is the northern lobe of a voluminous flow that originated near Miller Knoll. This flow is only one of several very youthful flows scattered over the Markagunt Plateau volcanic field of SW Utah.

A group of basaltic cinder cones and lava vents on the Markagunt Plateau east of Cedar Breaks National Monument has produced youthful, sparsely vegetated lava flows. Several lines of NE-SW-trending cinder cones are present within the volcanic field, with the youngest flows occurring near Panguitch Lake on the north and Navajo Lake on the south. Navajo Lake (upper right) formed when a thick, blocky flow from a nearby vent dammed Duck Creek. The oldest trees on the youngest flows are about 900 years old.

This unnamed cinder cone in the Sage Valley SE of Cedar Breaks National Monument was the source of one of the youngest lava flows in the Markagunt Plateau volcanic field in SW Utah. Extensive blocky lava flows cover broad areas near Navajo and Panguitch lakes.
