A narrow channel in the High Water Creek watershed within the Elk Fire burn area near Dayton, Wyoming is surrounded by steep, burned hillslopes. The section occurs upslope of where flood and flow deposits were observed. Rocky material and downed trees cover the surrounding hillsides.

View of the Elk Fire burn area from U.S. Highway 15 west of Dayton, Wyoming. Burned hillslopes lack vegetation and contrast sharply with the unburned terrain on either side of the highway.

Photograph of the Gros Ventre Slide 100 years after it occurred. View is to the south, with the landslide scar visible in the middle of the treed hillslope across the valley. Lower Slide Lake, which formed behind the landslide debris, is visible on the left side of the photograph. Photo by James Mauch, Wyoming State Geological Survey, June 7, 2025.

Oblique lidar shaded relief map looking east up the Gros Ventre River valley, Wyoming. The Gros Ventre Slide, which occurred on June 23, 1925, is outlined in black, and it moved from the high ridge on the south (right side of image) into the valley below. North-dipping sedimentary rock units are labeled in white, separated by white dashed lines.

Landsat 8 and 9 images of southwest Yellowstone National Park from 9-May (left), 25-May (center), and 18-June (right), 2025. The red labels are for the Madison (MP) and Pitchstone Plateaus (PP). The Yellow labels are for Shoshone (SL), Lewis (LL), Heart Lake, and Yellowstone (YL) Lakes. The Blue labels are for Lower (LGB) and Upper (UGB) Geyser Basins.

This frame capture of a video from a webcam shows a small eruption emanating from Black Diamond Pool in Biscuit Basin, a subbasin of Upper Geyser Basin in Yellowstone National Park, on May 31, 2025. This was the site of a hydrothermal explosion on July 23, 2024.

Water temperature in a runoff channel of Black Diamond Pool in Biscuit Basin, Yellowstone National Park, measured on May 31, 2025. The spike and subsequent drop over the span of about four minutes, followed by the low temperature recorded over about the following hour, is due to a small eruption that occurred from the pool at 8:39 p.m. that day.

Image from the webcam installed at Biscuit Basin in Yellowstone National Park. The view is of Black Diamond Pool, where a hydrothermal explosion occurred on July 23, 2024 (many of the rocks behind and to the right of the pool were deposited during that event). The background cliff is the Summit Lake rhyolite lava flow, which is about 111,000 years old.&n

Temporary webcam deployed on the boardwalk in Biscuit Basin, Yellowstone National Park. The pan/tilt/zoom camera provides a static view every 15 minutes and records video on site for later download as needed. Black Diamond Pool, site of a hydrothermal explosion on July 23, 2024, is in the background. This work was completed under Yellowstone Nation

View looking northwest at a new thermal pool in the Porcelain Basin area of Norris Geyser Basin, Yellowstone National Park, that probably formed in a series of mildly explosive events between late December 2024 and early February 2025. The rocks and white material (silica mud) surrounding the pool were probably ejected as the feature formed. The pool is

Map showing the Roadside Springs thermal area, located just north of Nymph Lake along the Norris-Mammoth highway. Hydrothermal ground is shaded purple. New hydrothermal features formed in 2003 on the north side of Nymph Lake, and also in 2024 a bit further north from the lake. Figure by Jefferson Hungerford, Yellowstone National Park.
