The Intermountain West Seamless Geologic Map Explorer is an interactive mapping application that hosts surficial and bedrock geologic data layers for a transect from the Rio Grande rift to the Basin and Range.

This mapper identifies wells that are monitored in the Upper Klamath Basin Oregon and California by U.S. Geological Survey (USGS), Oregon Water Resources Department (OWRD), and California Department of Water Resources (CDWR). This web page provides access to current and historic groundwater-level data collected by those agencies, as well as water-level graphs and maps.

Explore the geonarrative highlighting USGS research activities in transboundary watersheds in the northwest. The USGS is establishing baseline water quality conditions in rivers that cross the US-Canadian border.

The USGS Trails Explorer visualizes the current distribution of aggregated trails.

The location of the freshwater–saltwater interface along the coast is an important factor in the ecological and socioeconomic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including sea level, tides, winds, precipitation, streamflow, and tropical storms.
