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!

Original caption:” "Been adventuring and collecting shots all over Idaho this summer. I think I’d like to be a Peter Pan in the state of Idaho for the rest of my days….There were some really special local friends, like Russell Davies CEO from PTSD Veteran Athletes that performed all extreme mountain bike and kayak stunts, Matthew Matkin the featured fly fisherman out of Pocatello and so many more that lended their time and skills to make this possible! Thank you! And, thanks to John L. Scott Real Estate Boise for commissioning this dream video."

Head to one of the mountain ranges of Wyoming in this clip. Original caption:

"It's a place where alpine peaks tower above countless sparkling lakes and deep rugged canyons. A pristine wilderness with glaciers and snowfields, waterfalls, amazing wildlife, and some of the darkest night skies you’ll ever see: this is the Bighorn Mountains, a treasure of northern Wyoming. This time lapse film is an attempt to showcase this beautiful range in every season and weather condition, day and night. In this film is 3 years worth of time lapse footage (approximately 18,000 images) packed into 10 minutes. But even after all I've seen and captured it feels like I've barely scratched the surface."

Lost Lake

There are about 20 different lakes in Oregon named “Lost Lake”, but the name seems particularly appropriate for the one located in Willamette National Forest. Every summer the lake mostly disappears down a hole.

The shallow lake is located in a valley in the western slopes of the Cascade Mountain Range. The geologically active area is part of the Ring of Fire and volcanic eruptions have shaped the landscape. In Willamette National Forest, the landscape includes lava tubes.

Lava tubes form when surface lava cools and hardens while liquid lava underneath continues to flow downhill. Eventually this can leave a long tunnel along the path the molten rock was flowing. One such tube is open to the surface on the north side of Lost Lake, which may have happened as a result of a collapse. This open lava tube is what’s draining the lake.

In the winter small streams bring water into the lake faster than it can drain down the 2-meter (6-foot) wide hole; by summer the lake is draining faster than water is flowing in and the lake virtually disappears. It has not been determined exactly where the water goes. Lava tubes tend to be very porous so, most likely, the water seeps through the rock and recharges the aquifer below.

Lost Lake is not the only lake in the area that drains into a lava tube. Fish Lake, a few kilometers to the west, also seasonally disappears into a hole in the ground.

An Oregon newspaper called The Bulletin released this YouTube video of Lost Lake draining into the lava tube: http://bit.ly/1GOO6he
