Excelsior Geyser, which is inactive, fills a huge crater and produces some of the most prodigious overflows found. The crater measures 250 by 300 feet. The constant streaming overflow has been measured at about 4,000 gallons per minute. The overflow is discharged into the Firehole River. This picture is actually of Grand Prismatic Spring which is adjacent and which is the largest spring in the park. This photo shows the runoff channels of the spring. The brilliant colors are caused by the tiny thermophilic organisms that live in the spring. It was a beautiful afternoon when I shot this and I loved the reflections in the spring. I hope you all enjoy the shot.
Thank you to everyone who commented on my shot of the bison in Yellowstone. It is really a wonderful thing to be able to post a photo and be able to share it with so many fantastic photographers. I was sure impressed with the quality of the shots on smugmug today...even better than usual, I thought. You guys keep me motivated!
Hope you enjoy your day!
