The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)
The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.
Defining Native Ranges of U.S. Inland Fishes
Understanding the native versus non-native range of a species can provide useful information about dispersal, population distribution patterns, and human mediated movement across hydrologic barriers. The USGS Nonindigenous Aquatic Species (NAS) Program is working with partners to define native ranges of inland fishes in the United States to help identify which species should be included in the...
The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
Erosion of a Sea Stack Over 100 Years
The following photographs show the demise of Jump-Off Joe, a one-hundred-foot-high sandstone formation known as a “sea stack”. In 1890, the sea stack was composed of middle Miocene concretionary sandstone of the Astoria Formation. Yaquina Head on the Horizon is composed of middle Miocene basalt flows and breccia. Note remnant of Pleistocene terrace deposit along the wave cut bench on the stack...

Chinook Salmon Use of Eelgrass Habitats Skagit River Delta Washington
The degree to which eelgrass on river deltas provides critical habitat for estuarine fishes, especially out‐migrating juvenile salmon, is an important scientific and management issue that bears on efforts to conserve and restore both eelgrass and fish.
Columbia torrent salamander (Rhyacotriton kezeri)
Torrent salamanders are Northwest-U.S. endemic, headwater-stream-associated amphibian species that have a dearth of basic ecological information, but are thought to be highly vulnerable to habitat changes.

Rear-arc basalt lava outcrop
A 3-4m (10-12 ft) high outcrop of basalt lava, part of a broader lava flow. These flows were erupted about 300,000 years ago following basalt dike intrusions in a rear-arc region of northern California. The eruptions of three of these flows are thought to have taken place within several hundred years of each other.

Alder root nodules
Root nodules are a symbiotic relationship between a plant and nitrogen-fixing bacteria. A symbiotic relationship is one where both organisms benefit. Nitrogen-fixing bacteria change inorganic nitrogen from the air into ammonia, a form of nitrogen most organisms can use. They also use a process called rock dissolution to release other nutrients, such as calcium and

Male leafcutting bee (Megachile) approaching an Origanum
The alfalfa leafcutting bee (Megachile rotundata) is an introduced species common to Southwest Idaho. They originate from the old world, most likely from northeastern Africa or the Middle East. These bees are successful pollinators of various crops and have been imported to North America for use in agriculture and beekeeping.
The atypical location of Mount St. Helens may be due to geologic structures that control where deep magmas can rise through the crust, as suggested by new findings published today in Nature Geoscience.

Data Will Provide a “Snapshot” of the Eastern Snake River Plain Aquifer
TACOMA, Wash. — The U.S. Geological Survey recently published the results of a new five-year suspended-sediment and water temperature study from the Sauk River. The purpose of this study is to improve understanding of the magnitude and timing of suspended sediment from the Sauk River and its tributaries to the Skagit River.
BONNERS FERRY, Idaho — From Sept. 24 through 29, scientists from the U.S. Geological Survey will conduct dye tracer and aerial mapping studies on northern Idaho’s Kootenai River. Data from the studies will support Idaho Department of Fish and Game and Kootenai Tribe of Idaho fisheries and river restoration projects.
A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study by the U.S. Geological Survey.
A carbonatite here, a glacial moraine there, a zig-zagging fault or two, even a behemoth of a batholith. The geology of the 50 States is an enormous patchwork of varied forms, beautiful in their variance but challenging to present as a single map.
The U.S. Geological Survey awarded approximately $4.9 million this week to six universities and a university-governed non-profit, to support transitioning the west coast “ShakeAlert” earthquake early warning system into a production system.
