Geologic Map PortalZoom in to different parts of the state to explore detailed geologic maps where available. View, create, save, and print custom maps, find out about geologic formations, and download GIS data.
New Maps & PublicationsNew maps and publications published by the Utah Geological Survey.
Geologic MapsGeologic maps use a combination of colors, lines, and symbols to depict the relative age, composition, and relationships among rocks and sediments at and near the earth’s surface.
Geologic Hazard MapsGeologic-hazard maps generally show areas that may be subject to the effects of earthquakes, landslides, debris flows, rock falls, poor soil conditions, radon, or floods.
Groundwater MapsThese maps show areas of groundwater recharge/discharge, groundwater sensitivity and vulnerability to pesticides, and groundwater quality.
Topographic MapsTopographic maps show the 3-dimensional surface of the earth in 2-dimensions using elevation-contour lines set above or below a specified reference, such as sea level.
GIS DataGIS (Geographic Information System) is a computer system that allows the user to create specialized maps with a variety of spatial data which can include topographic features, geologic units, energy or mineral resources, and geologic hazards.
Energy & Mineral Resource MapsEnergy resources include fossils fuels and geothermal energy. Mineral resources are rocks and minerals that are extracted or “mined” from the earth and used for human’s benefit.
Geophysical MapsGeophysical maps show the variability in physical properties of different rock types including density, thermal attributes, seismic velocity, magnetic susceptibility and other electromagnetic parameters.
