Journey Down a Hot Spring
This video was taken at Little Hot Creek by taping my GoPro camera to a crowbar and submerging it into a hot spring. Notice the bubbles on the underside of the carbonate growths. The green and orange are microbial biofilms associated with the mineral that is precipitating on the side of the spring.
Wait until the end of the video for some great shots of the inside of the spring itself. At the very end, we were concerned that we had cooked our camera (88 oC, ouch!) because the wifi kicked out but it came back to life.
