Timelapse Captures the Grandeur of Yellowstone at Night

Yellowstone became the first designated national park in 1872 for good reason. The area—which spreads across Wyoming, Montana, and Idaho—is treasured for its sprawling vistas, majestic wildlife, and ongoing geothermal features, which are fueled by the Yellowstone Caldera, the biggest supervolcano in North America.

Millions of people flock to Yellowstone every year to take in the park’s dynamic and spectacular sights, but thanks to the team at the Skyglow project, you don’t have to book a plane ticket to get in on the action. Creators Harun Mehmedinovic (who shot and edited) and Emina Becirovic (who produced) created a timelapse that displays the park’s thermal activity in all its glory, including a view of Yellowstone at night tha most have never seen.

Part of the Skyglow project’s initiative is to examine the effects of light pollution on dark sky environments, and was created in conjunction with the International Dark-Sky Association.

Geological Map Shows the Massive Reservoir Bubbling Beneath Old Faithful

Yellowstone National Park is home to rivers, waterfalls, and hot springs, but Old Faithful is easily its most iconic landmark. Every 45 to 125 minutes, visitors gather around the geyser to watch it shoot streams of water reaching up to 100 feet in the air. The punctual show is one of nature’s greatest spectacles, but new research from scientists at the University of Utah suggests that what’s going on at the geyser’s surface is just the tip of the iceberg.

The study, published in the journal Geophysical Research Letters, features a map of the geological plumbing system beneath Old Faithful. Geologists have long known that the eruptions are caused by water heated by volcanic rocks beneath the ground reaching the boiling point and bubbling upwards through cracks in the earth. But the place where this water simmers between appearances has remained mysterious to scientists until now.

Using 133 seismometers scattered around Old Faithful and the surrounding area, the researchers were able to record the tiny tremors caused by pressure build-up in the hydrothermal reservoir. Two weeks of gathering data helped them determine just how large the well is. The team found that the web of cracks and fissures beneath Old Faithful is roughly 650 feet in diameter and capable of holding more than 79 million gallons of water. When the geyser erupts, it releases just 8000 gallons. You can get an idea of how the reservoir fits into the surrounding geology from the diagram below.

After making the surprising discovery, the study authors plan to return to the area when park roads close for the winter to conduct further research. Next time, they hope to get even more detailed images of the volatile geology beneath this popular part of Yellowstone.

31 Facts About National Parks

A little over 100 years ago, President Woodrow Wilson signed the National Park Service into law, ensuring that the country’s most remarkable natural landscapes would be preserved for future generations. Today, national parks are more popular than ever, with millions of visitors passing through the system’s 400-odd properties each year. But even if you’re working to check every national park off your bucket list, you may be unfamiliar with some of these facts. For instance, did you know that Dolly Parton is an official ambassador to Great Smoky Mountains National Park? Or that Yosemite campaigned to host the Winter Olympics in 1932?

That’s just some of the trivia John Green shares in this latest video from Mental Floss on YouTube. You can check out all 31 facts above, then subscribe to our channel if you're still hungry for more brain food.
