Mudslide Interative Shows Scope of Disaster in Oso, WA

When there is a natural disaster, The New York Times website often features great interactive graphics to help viewers understand what happened. These resources have proven very helpful as I explain recent disasters to my students. Their graphic to illustrate the scope of the recent mudslide in Washington is another great one, allowing viewers to compare the Oso area before and after the recent tragedy.

CLICK HERE to see the resource - Once the page opens up, select "before" or "after" in the upper right to compare.

Craters of the Moon Animation

From Regents University of California - This week's resource is an animation that shows the timing and extent of lava flows that created the Craters of the Moon volcanic area in south-central Idaho.

CLICK HERE to view the animation.

This recent volcanic activity at the Craters of the Moon is thought to be caused by "leftovers" from the hot spot that currently sits beneath Yellowstone Park. In fact the Snake River Plain IS the path of the hot spot* over the past 15 million years. To learn more about the geologic past of this area CLICK HERE.

Another interesting aspect of the hot spot is the impact it had on ancient rhinos in Nebraska - CLICK HERE to learn more about that chapter in the geologic story of the area.

*Actually, it is the North American Plate that has been moving over the stationary hot spot.

Blog Site to Cover Earth History in 2014

Richard Gibson is an author, geologist, historian and tour guide in Butte, Montana. On January 1st Gibson started a blog that aims to explain (in one year) important happenings in Earth's history in chronological order: History of the Earth Calendar

For what I'm interested in, this is one of the best resources I've come across in awhile. The very impressive site includes photos, diagrams, text as well as short PodCasts. Each day Gibson helps the reader/listener understand one aspect of Earth's history. You can go back to January 1st and get caught up, or you can pick and chose based on your interests. I have always been fascinated with the "Belt Supergroup", so I wanted to see what Gibson had to say about it - I found that it had been the focus of his January 24th post, and I was not disappointed!
