The Earth Story

@earthstory / earthstory.tumblr.com

This is the blog homepage of the Facebook group "The Earth Story" (Click here to visit our Facebook group). “The Earth Story” are group of volunteers with backgrounds throughout the Earth Sciences. We cover all Earth sciences - oceanography, climatology, geology, geophysics and much, much more. Our articles combine the latest research, stunning photography, and basic knowledge of geosciences, and are written for everyone!
We hope you find us to be a unique home for learning about the Earth sciences, and we hope you enjoy!

Pulpit terrace print This is a really neat image. This is Pulpit Terrace, part of Yellowstone’s Mammoth Hot Springs named because it looks so much like a preacher’s pulpit from the side that you can find old photographs of people standing behind it and looking like they’re preaching (see our twitter page below). This image shows it as it appeared in 1898, but it’s not a photograph.

Classic map The Yellowstone area was declared America’s first National Park in 1872. For decades, no one really knew what a national park meant other than it was something of an interesting area – the U.S. Army even occupied the territory for years to provide some amount of protection for its resources against outsiders who wanted to make money off of the park’s features. Even though no one really knew what a national park was, within 6 years of the park being declared, geologists had a basic idea of what was going on there, as shown by this 1878 vintage geologic map.

Backpacking trip to the headwaters of the Yellowstone River. Original caption:

"This day 1-3 of an 8 day backpacking trip with my buddy Joey of @myownfrontier in the Greater Yellowstone, Teton Wilderness area. This is Wild America at its best as far as my experience goes. We go into some of the most wild and remote areas of the lower 48 states and find the headwaters of the Mighty Yellowstone River. Amazing vistas and views as we traverse the Continental Divide in the middle of an incredible wildflower bloom. Stunning waterfalls, meadows, mountains and creek crossings everywhere in prime Grizzly country. Part 2 will be out soon and will take us from the North Fork of the Yellowstone River, over to and through the Thorofare Creek drainage, Open Valley, Overlook Mountain, Glacier Basin, Rampart Creek and much more. We didnt see any people except for the first and last day. This trip is from outside the boundaries of Yellowstone National Park."

The Great Rift The mountains of Idaho are split by a wide valley known as the Snake River Plain. Much of this landscape was once volcanic, as massive eruptions associated with the Yellowstone Hot Spot blasted their way across the state over the past 20 million years, flattening the mountains as you see here. Every so often, molten rock associated with the Yellowstone system finds a new path it can take up to the surface, and none have been more active recently than the Great Rift.

Steamboat Geyser, in Yellowstone National Park's Norris Geyser Basin, is the world's tallest currently-active geyser. And here we see it erupting. Impressive!

Steamboat geyser has been erupting pretty often for the last year and a half - not shooting the full football field in height it has before, but erupting every few days to every few weeks. Its behavior is totally unpredictable.
