Continued slow rise of water level at bottom of Halema‘uma‘u
The water level continues to slowly rise at the bottom of Halema‘uma‘u, resulting in enlargement and merging of the small ponds. Today, the second and third ponds (top of image) observed over the weekend have merged, and are nearly connected to the main pond (bottom of image). For scale, the main pond is about 15 meters (yards) wide.

With the help of a powerful telephoto lens, HVO geologists confirmed today that there are two areas of ponded water at the bottom of Halema‘uma‘u. Using a laser range finder from their observation site, they were able to measure the two greenish ponds.

This image shows an area of greenish fume (near top of photo) east of the water pond (center) at the bottom of Halema‘uma‘u. This fume could suggest another emerging area of ponded water, but this has not yet been confirmed. HVO continues to closely monitor the area, and will report any significant changes.

While making observations today, HVO geologists noted a koa‘e kea (white-tailed tropicbird) gliding across the ponded water at the bottom of Halema‘uma‘u. The bird is visible in the top left quarter of the photo. USGS photo by M. Patrick, 08/03/2019.

Small pond of water in Halema‘uma‘u as viewed from the caldera rim
The water pond deep within Halema‘uma‘u is impossible to see from most areas along the rim of Kīlauea's caldera. But one potential viewpoint on the rim was examined today by HVO geologists, who were able to see the small pond of water at the bottom of the crater, despite poor weather and fleeting views through fog.

Congressman Charlie Crist visits the SPCMSC
On May 6, 2019, Congressman Charlie Crist (13th district, FL) and Operations and Outreach Director Mr. Kendrick Lewis will visit the St. Petersburg Coastal and Marine Science Center (SPCMSC). Congressman Crist requested this visit because he is interested to learn more about the Center and to discuss needs/priorities that we may have.

Whiskey Creek section of Whiskeytown Lake
In the aftermath of the 2018 Carr Fire, northern California, sediment has eroded from burned hillslopes and accumulated in some areas of Whiskeytown Lake. A recent sediment deposit is shown here in the Whiskey Creek section of the lake.

Glacial erratic near the Grand Canyon of the Yellowstone in Yellowstone National
This huge boulder was dropped by a retreating glacier on the north rim of the Grand Canyon of the Yellowstone in Yellowstone National Park, and it is a testament to Yellowstone's icy past.
