Map depicting Valle De Lajas and Río Loco drainage, the westernmost zone of the study area. Pie charts summarizing Sr isotope mixing model results. River sediment sample locations are represented by an X, bedrock sampling locations by open circles. An infilled black rectangle shows Bahía de Guánica sediment sampling location (NS-01).

In 2023, scientists with the USGS Pacific Coastal and Marine Science Center completed a 3-week field operation in Lake Chelan, Washington, the third deepest lake in the conterminous United States, to acquire sediment cores, high-resolution bathymetry data, and chirp sub-bottom profiles.

Long before explosive eruptions formed the Yellowstone Caldera and heat from the magmatic system began feeding a dynamic hydrothermal system, there was the Absaroka volcanic range. Remnants of the rugged terrain are still visible on the east and north sides of Yellowstone National Park.

Over the past few decades, an area on the north rim of Yellowstone Caldera has risen and fallen. Just last year a new period of uplift in this area began!

Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
