Timelapse view of the Kīlauea summit water pond
This timelapse video covers about 30 minutes of activity at the water pond in Halema‘uma‘u at the summit of Kīlauea. Water appears to be flowing into the pond from several locations, including the southern boundary (right side in this image). A small amount of material is also seen floating on the surface at the eastern end of the pond (top of image).

Carrying a tubed rattlesnake
Boise State University Master’s student Kristina Parker carries a Great Basin rattlesnake (Crotalus oreganus lutosus). The snake’s head is enclosed in a plastic tube to allow her to safely handle it during the biological sample collection process.

Collecting a blood sample from a rattlesnake
Boise State University Master’s student Kristina Parker uses a syringe to collect blood from a Great Basin rattlesnake (Crotalus oreganus lutosus). The blood’s ribonucleic acid, or RNA will be analyzed to track genetic change in the snake from habitat disturbances. RNA, along with deoxyribonucleic acid – or DNA, are the molecules that carry genetic information.

Video of circulation in the Halema‘uma‘u water pond
Video of circulation in the Halema‘uma‘u water pondThis time-lapse video shows circulation in the water pond in Halema‘uma‘u over a period of about 25 minutes. There appears to be an influx of water along the southern (right) shoreline. A broader eastward flow of water (toward top of image) is evident. The video is shown twice. USGS video.

Two views of the Halema‘uma‘u water pond
Views of the water pond in Halema‘uma‘u on Friday, September 6, and Monday, September 9 are shown in this video. Ripples are evident on the pond, presumably due to wind moving over the water surface. No significant changes in the pond were observed over the weekend, and the water level continues to slowly rise. USGS video by M. Patrick.
