USGS photo library
Photo by J.D. Griggs, March 28, 1983. US Geological Survey
The US Geological Survey has a terrific photo library that is well worth seeing. The above image, of the eruption of Kilauea Volcana in Hawaii in 1983, is one of many spectacular images to be found there. Images are free to view and download, subject to these terms.
(Thanks to my sister for the link).
That is so very cool.
