"Tucked away in the Norris Geyser Basin is Steamboat Geyser, the world’s tallest active geyser. Its major eruptions shoot water more than 300 feet (91 m). Only Waimangu Geyser in New Zealand has rocketed to greater heights—but not in more than one hundred years.

Looking down from the lookout point at Brink of Lower Falls, over the Yellowstone River, as it flows eastward through the "Grand Canyon of Yellowstone".

On the drive south of Mammoth Springs, you pass through Silver Gate which is a landslide deposit of travertine stone at least 400,000 years old. 

Looking down on the lower portion of Artists' Paintpots in Yellowstone National Park, Wyoming. Artists' Paintpots is a hydrothermal area with many colorful mud pots, hot springs, and geysers.

A view of Roaring Mountain in Yellowstone National Park, Wyoming. "Roaring Mountain is a large, acidic thermal area (solfatara) that contains many steam vents (fumaroles). In the late 1800s and early 1900s, the number, size, and power of the fumaroles was much greater than today." (NPS)

A Motus tower installed on the spillway of the former Glines Canyon Dam in Olympic National Park. The solar-powered array of radio antennae will detect the signals send by tiny transmitters known as “nanotags” that have been attached to small flying animals. This tower was installed to study bat movement behavior.

Researchers examine a bat wing while in the process of capturing bats to attach tiny Motus radio tags to track their movements.

A researcher holds a myotis bat during the process of capturing bats to fit them with Motus transmitters.

A team of biologists prepares to measure, weigh, and tag a captured bats. On the left, USGS biologist Gabe Reyes has a bat in a bag, used to separate and calm the bats. USGS biologist Julia Ersan is holding some alcohol used to ensure clean instruments and work surfaces, and USGS biologist Austin Waag is getting something out of a backpack.

Shown here are three SCUBA divers installing shade structures over experimental Elkhorn corals (Acropora palmata) that have become "bleached," that is, lost all their algal symbionts (also called zooxanthellae) because of the summer 2023 ocean-heat wave. The corals are attached to cement blocks as part of the U.S.
