In September 2005, USGS/YVO Postdoctoral Fellow Brita Graham Wall used a radio-controlled camera, attached to a helium-filled balloon to take photos from the sky above the Norris Geyser Basin. Brita used these photos to gain insight into the distribution of cracks and fractures that feed the hot springs at Norris. Some of the photos are truly spectacular, and we hope you enjoy them.
