Volcano and lavaOur area was a hotspot of volcanic activity during ancient times. Large and small volcanoes played a significant role in defining Millard County's topology. Eroded volcanoes and lava flows can still be seen in many places. None of the volcanoes are active, but the area's many geothermic springs suggest there are still hotspots not far beneath earth's surface.

Location Map

If you pay attention, you'll see volcanoes while along driving area roads. It's fun to see them, and even more fun to hike amid the lava boulders - maybe even climb to the top of a cinder cone.

Volcanic MountainThe remains of old volcanoes can easily be seen from I-15 around Kanosh and Cove Fort, and from Hwy 257 in the Black Rock area, about 52 miles south of Delta. In the distance you can see several mountains that have that dramatic volcano shape.

There are no formally designated "volcano tour" drives or hikes, but plenty of opportunity to see and hike on volcanoes as you explore the back roads.

The photos on this page were taken at a small cinder cone located between Kanosh and I-15. From the center of Kanosh, just follow the graveled road west and you'll skirt along the northern edge of the volcano. Views are impressive from the road, and even better if you get out and hike.

Lava rocks in all shapes and sizes can be found here, ranging from tiny cinders to huge crystals. Some are black, some red. Many have sharp edges so take care as you hike through them.
