This is a geologic map showing the Quaternary geology of the state of Wisconsin. It is an update to an older map that was published in 2025 after many years of mapping done by the Wisconsin Geological and Natural History Survey. 

Fort Peck Lake, a sprawling reservoir formed by the Fort Peck Dam on the Missouri River, lies in the eastern prairie region of Montana near the city of Glasgow. According to the U.S.

Mount Etna is Europe’s largest and most active volcano. Located on the eastern coast of Sicily, Italy, in the province of Catania, the active stratovolcano is known for its frequent and persistent eruptions. Activity can range from explosive eruptions to lava flows and ash emissions.

The Chesapeake Bay is roughly 200 miles (322 kilometers) in length and varies in width from a mere 4 miles (6.4 kilometers) near Aberdeen, Maryland, to 30 miles (48 kilometers) near Cape Charles, Virginia.

The Chesapeake Bay watershed has experienced substantial population growth over the last several decades. Since 1950, the population has more than doubled, and between 1980 and 2023, the number increased from 12.7 million to 18.6 million.

The Chesapeake Bay is the largest estuary in the United States. Located in the Mid-Atlantic region of the East Coast, it runs north-south from the mouth of the Susquehanna River near Havre de Grace, Maryland, to the Atlantic Ocean near Virginia Beach, Virginia.

The Chesapeake Bay watershed spans more than 64,000 square miles (166,000 square kilometers) and encompasses parts of six states—Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia—and the District of Columbia.

A bird’s eye view of the Thacker Pass lithium mine captured in late February 2025 reveals the contours of the process plant pad taking shape. Lithium Americas, the company that owns the mine, used Landsat data to help determine its potential impact on sagebrush environments and groundwater.

On Tuesday, January 21, 2025, Winter Storm Enzo brought an exceptionally rare snowfall to the Greater Houston metro area of Texas. The National Weather Service reported 5.5 inches (14 cm) in Baytown, a city located east of Houston on the northern shore of Galveston Bay. Other cities and locales received upwards of 3 to 4 inches (7.6 to 10.2 cm).

The USGS provides research-quality, applications-ready Landsat Level-2 and Level-3 science products to support an array of land surface change studies. Collection 2 Level-2 scene-based science products include Surface Reflectance, Surface Temperature, Surface Reflectance-Derived Spectral Indices, and Provisional Aquatic Reflectance.

Louisiana is home to numerous salt domes, including the five distinct coastal salt dome islands that can be found in the southern part of the state near the Gulf of America. Formed by the upward pressure of ancient salt deposits, these hills rise above the surrounding marshes and coastal plains of Louisiana.

The tragic fires sweeping across the Greater Los Angeles area in January 2025 have burned more than 40,000 acres, destroyed more than 12,300 structures, and prompted evacuation orders and warnings for as many as 200,000 residents. Exceptionally dry conditions, coupled with strong Santa Ana winds, have fueled the fires.

Landsat 8 and Landsat 9 kicked off 2025 by acquiring over 1,400 scenes on the first of January. This Landsat 9 image of Emi Koussi in the Tibesti Range of Chad is a mosaic of two of the many scenes collected. Emi Koussi is an extinct shield volcano that rises to 11,204 feet (3,415 meters) above sea level, making it the highest summit in Chad and the Sahara Desert.

Existing surficial geologic maps of project areas to be converted to digital geologic databases (Barry and Van Buren counties) and web-based maps (Allegan County).

This map shows 2024 shrub cover from the Rangeland Condition Monitoring Assessment and Projection (RCMAP) project across the McDermitt Caldera, outlined in gray, along the Nevada–Oregon border. Dark green areas indicate high shrub cover, typically found in riparian zones and at higher elevations.

On December 12, 2024, heavy lake effect snow blanketed the Buffalo, New York metro area with over 2 feet accumulating in less than 24 hours. This area normally receives heavy snowfall each year during the Northern Hemisphere winter months due to being situated along the shore of Lake Erie. 

The Wind River Range, located in west-central Wyoming, is a unique wilderness area that rises from the high plains of the South Pass of the Continental Divide and runs northwest to the Yellowstone Plateau. The Winds, as they are affectionately known, are exceptionally long, wide, high, rugged, and remote.
