Long before explosive eruptions formed the Yellowstone Caldera and heat from the magmatic system began feeding a dynamic hydrothermal system, there was the Absaroka volcanic range. Remnants of the rugged terrain are still visible on the east and north sides of Yellowstone National Park.

Summer is here, and millions of people will be visiting Yellowstone National Park. People with questions. What is this scat I’m seeing? How does a geyser erupt? What makes Yellowstone so special?

Where’s the bathroom?

Did you hear that???  Well, Roaring Mountain isn’t quite as loud as it used to be, but it’s still one of the hottest thermal areas in all of Yellowstone National Park!

KABOOM! That’s what Yellowstone is famous for – huge explosive volcanic eruptions. There’s really nothing brewing right now, the magma chamber is mostly solid, but there have been quite a few hydrothermal eruptions and small explosions in both Biscuit Basin and Norris Geyser Basin as water in the hydrothermal system flashes to steam.

Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
