Two geologists working for the Oregon Department of Geology and Mining Industries has made a fascinating discovery. They found evidence suggesting an area in Central Oregon near Prineville, is the remains of an ancient super-volcano that is 29 million years old.This discovery is still being reviewed, but if true, the Crooked River Caldera is another piece to the puzzle that is Oregon's complex geology.For more information:http://www.oregongeology.com/sub/publications/OG/OGv67n01.pdfFor the original news story:http://www.ktvz.com/Global/story.asp?S=9149452#

Dec 2, 2008 - Ooooh, not another caldera.. Humm, this part of the planet must have been a riot. Hope we don't ever see anything like this anything anywhere! Nice video. Hope the holidays are working up well for you down there.

Dec 2, 2008 - I first came across news about the Crooked River Caldera, while I was on vacation in Bend, OR about a month ago.If proven to be true (it is a fairly recent discovery and it has not yet been accepted), the caldera can provide some interesting answers, like the large pyroclastic flow formations at the John Day Fossil Beds, located about 100 miles to the east, which dates to about the same age as the date provided for the caldera.Thanks for watching.

Dec 2, 2008 - Is this about the same age as the last eruption of the one in Wyoming, etc.? Thanks for this video.

Dec 2, 2008 - A good question. However, more study is needed to determine if there is a connection between Crooked River and Yellowstone.There is an Oregon connection to the Yellowstone Hotspot. The first known location where the hot spot first erupted is called McDermitt Crater, which sits along the border between Oregon and Nevada. It erupted about 17 million years ago.As the North American plate moved southwest, the hot spot has remained stationary, erupting many along the Snake River Plain.
