Utah company brings landscapes to life — in 3-D

Map-making is nearly as old as civilization itself. But a professor and his former student at Utah State University claim to have found a new way to do it.

Field Reviews Coming Up

Hey everyone! We’ve got two field reviews of new geologic mapping are coming your way. One trip will cover the Willard Quadrangle, the other will cover the Salt Lake City North and Baileys Lake Quadrangles. Please see the images for more information.

What Earthquake Maps Should Really Look Like

When we hear that a magnitude 8 earthquake has struck, we know that’s worse than a magnitude 4 earthquake. But how much worse?


Best Student Map Competition

Hey Geology students!

The US Geological Survey (USGS) National Cooperative Geologic Mapping Program (NCGMP) in partnership with The Geological Society of America (GSA), GSA Foundation, Association of American State Geologists (AASG), American Geosciences Institute (AGI), American Institute of Professional Geologists (AIPG), and the Journal of Maps invites students to participate in the Best Student Geologic Map Competition.

Geologic Map Of The Santa Clara Quadrangle, Washington County, Utah

M-271DM Map Santa Clara Quadrangle

By: Grant C. Willis and Janice M. Hayden

The Santa Clara 7.5′ quadrangle is in the northwestern part of the St. George basin in southwestern Utah, and includes Santa Clara and Ivins Cities, and colorful Red Mountain and Snow Canyon State Park. Movement on an underlying thrust fault created a variety of faults, joints, deformation shear bands, and brecciated rock in Triassic and Jurassic strata in many areas. Remnants of six Quaternary basalt flows cap ridges and benches, forming classic inverted valleys, and form lava cascades in Snow Canyon State Park. The young Santa Clara flow cascaded through Snow Canyon and flooded across broad benches, forming scenic black terrain that contrasts sharply with red-brown to near-white sandstone cliffs. Landslides, rock falls, swelling clays, and other geology and related flooding and debris flow hazards have caused extensive damage in recent years and present increasing challenges as growth and development continue. “Blue Clay” of the Chinle Formation has been at the root of significant damage to roads, buildings, and infrastructure.

By: Daren T. Nelson and Paul W. Jewell

The Hogup Bar quadrangle is located southeast of Park Valley, Utah, and west of the northwest arm of Great Salt Lake. Late Pleistocene Lake Bonneville sediments and related shorelines dominate the landscape, and record the transgression and regression of Lake Bonneville. Surficial deposits overlie Tertiary basalt and Permian-Pennsylvanian sedimentary bedrock.


Utah agencies partner to share high-resolution map information

New technology is available to Utah information systems that will facilitate faster decision-making and improve management for government and businesses across the state.

USGS launches a billion-dollar initiative to map the West in 3D

LIDAR, or Light Detection and Ranging, uses lasers to create intricate three-dimensional maps in places where bad weather or thick vegetation hampered traditional aerial mapping. Though the technology itself isn’t new, it’s about to become more widespread: The 3D Elevation Program, a billion-dollar initiative launched this summer by the U.S. Geological Survey and numerous partners, seeks to remap the country using LIDAR — and make the maps public. “There doesn’t seem to be a limit to how creative people can use this technology,” says Kevin Gallagher, associate director for USGS Core Science Systems. “It’s like looking at the world through a new pair of glasses.”
