High-resolution satellite images of the Porcelain Basin and Nuphar Lake areas of Norris Geyser Basin acquired by Quickbird-2 on September 11, 2006 (left), WorldView-3 on July 7, 2016 (middle), and WorldView-3 on March 30, 2022 (right).  Note the change in color of Nuphar lake, from deep green to light blue, over time, as well as the increased evidence of flow from thermal features on the east side of Porcelain Basin into the lake, as indicated by the death of trees and appearance of white sinter deposits.  Cool-water seeps are also apparent into Porcelain Basin in the 2022 image.  Data processed by Greg Vaughan, USGS.
