Reconnaissance geologic map of the Sliderock Mountain area, Sweet Grass and Stillwater counties, Montana

The remains of a deeply eroded Late Cretaceous stratovolcano centered near Sliderock Mountain dominate the map area. The volcano consists mostly of lahars, although basaltic andesite lava flows are also present. An extensively eroded, weakly mineralized hypabyssal intrusive complex, inferred to represent the volcano's solidified magma chamber, intrudes previously erupted lava flows and associated

Shoreline and coastal wetland variability along the west shore of Green Bay, Marinette and Oconto counties, Wisconsin

Coastal wetland ecosystems along the Great Lakes shorelines are extremely valuable natural resources. They provide numerous environmental and recreational benefits, and they serve as critical habitats for fish and wildlife populations. In general terms, wetlands can be defined as lands transitional between terrestrial and aquatic systems; they are characterized by periodic submergence or a water t

Temporal variability of shoreline positions and coastal wetlands along lower Green Bay, Oconto and Brown counties, Wisconsin

The positions of shorelines and the areal extent of adjacent coastal wetland tracts in the Great Lakes region have exhibited substantial temporal variability during both prehistoric and historical times. Shoreline migration has resulted in environmental problems such as flooding and the coastal erosion of lakefront property, as well as the destruction of coastal wetland resources. In the Great Lak

Bathymetry of the west-central slope of the island of Hawaii

This map shows the topography of a small part of the subaerial western part of the Island of Hawaii as well as modern multibeam bathymetry of the west submarine flank, which covers a total area of about 8,500 km2 ( see index map). The map area includes part of the submerged flanks of the active Mauna Loa and Hualalai Volcanoes, which last erupted in 1984 and 1801 respectively. The steep and irregu
