Upper Green River Valley Time-Series Images

We've just added to our time-series of images showing the spread of drilling in the Jonah and Pinedale Anticline natural-gas fields, located on public lands in western Wyoming's upper Green River valley -- the southern part of the Greater Yellowstone Ecosystem. The new images are SPOT XS satellite pics taken in September 12, 2006 and September 27, 2007. We've applied a "natural-color" process to these images so that vegetation will appear green and water blue, in keeping with the earlier Landsat images in these series. Drilling is booming in both fields, with new drilling plans released by the Bureau of Land Management last year that will add thousands of new wells to these fields.

Google Earth users, download the KMZ file for the Jonah Field to explore the roads, well pads, and other facilities in this area in 1-meter detail; the Google image was taken in August 2006.

Go here to learn more about drilling in this area and what you can do, and here to read more about SkyTruth's other work in the upper Green.
