One of the more spectacular sights in the National Park System is at Hawaii Volcanoes National Park when red-hot lava streams into the Pacific Ocean.

Visit the park at night when the lava is pouring into the ocean and you'll be treated to quite the show.

To help visitors understand this process, the National Park Service and U.S. Geological Survey have produced this short video.
