Mammoth Cave is made up of multiple lava tubes within the vast lava flows on the Markagunt Plateau region of Dixie National Forest in Utah. The 12,000 foot Duck Creek Lava Tube is among the longest and highest lava tube in the United States. This easy out and back trail is accessible by all types of vehicles and a great spot to take the entire family. There are multiple cave entrances that you can easily walk down into. The lava tubes run in different directions and exit up to the surface at several points. Volcanism in the Markagunt Volcanic Field occurred between 2.8 and 5.3 million years ago. The area's cinder cones and lava flows produced during this stage are now heavily eroded. The second stage of volcanic activity occurred between 800,000 and 500,000 years ago. Its cones and lava flows are only moderately eroded. If you plan to explore deep in the caves, be sure to bring a flashlight or two.
