Off Firehole Lake Drive you come to Surprise Spring, a crystal clear hot spring with an intermittent steam eruption. It was not super active on the day we visited, but it is still surprising and surprisingly beautiful. Just look at those colors. The video captures it a bit better. Sony a5100 with the Sony E 10-18 f4 zoom at 15 and 27mm equivalents. Program mode and, obviously, movie mode. Processed in Photomator. Video edited in Lumafusion and VidDay (resizing for posting).
