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.

Geologic Map of Unconsolidated Deposits in the Hogup Bar Quadrangle, Box Elder County, Utah

MP 15-2DM, Hogup Bar Quadrangle, Box Elder

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.

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

hcn.org

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.”
