Yellowstone’s Jake Lowenstern on YouTube 20 April 2009

Jake Lowenstern is the scientist-in-charge at the Yellowstone Volcano Observatory. There’s a three-part presentation by him available on YouTube, talking about Yellowstone and the work his team does there. For more, including links to all three videos, see Callan Bentley’s NOVA Geoblog: Lowenstern interview on YouTube.

Tip of the hat to Callan Bentley for telling us about this, and to his former student Stef who told him about it.

I found a peculiarity while logging the latest earthquake activity in Google Earth at the coordinates listed below that does not show up in previous images using the Google Earth “Historical Imagery” feature. I don’t know what it is but it is in the center of area that is smoking in the current image and smoking in the 2006 imagery. You seem to be the best person to ask what this might be.

Today I was locating the latest earthquake information in Google Earth and found an oddity on the Yellowstone caldera. In looking back through the historical imagery this oddity does not show up but the area showed smoke in the 2006 imagery which it still does in the latest imagery but with this oddity now in the center of it. What is it?

I really don’t know: could it be an excavation of some kind? Although given the shadow directions, it looks more like a structure or a pile of something. It’s a mystery to me. Suggestions welcomed.

Another question about the same area but further northeast are the areas of tree kills that are much different than what you see after a fire. These areas are patchy grey with edges in the shape of blobs with dead trees interspersed all throughout (large brown areas among the green of live trees.) Has any soil CO2 saturation surveys been done in these areas or ground temperature readings been done like in the Norris Geyser Basin? Again, these features do not exist in the images captured before 2006 and there is a definite difference in how these tree kill features appear as opposed to the fire scars from the Yellowstone fire of 1988 further south. Put your “Eye alt” out to around 20,000 feet to see the extent of this arc of tree kills. I am just curious since I have seen similar at Mammoth Mountain in California but not nearly as extensive.
