The Gigantic Markagunt and Sevier Gravity Slides Resulting from Mid-Cenozoic Catastrophic Mega-Scale Failure of the Marysvale Volcanic Field, Utah, USA

By: Robert F. Biek,Peter D. Rowley,David B. Hacker

The Markagunt and Sevier gravity slides are gigantic landslides that resulted from gravitationally induced catastrophic failure of the southern flank of the Oligocene to Miocene Marysvale volcanic field. Each is nearly 100 km long with runouts over the former land surface>35 km; together they span 7000 km2 and rank among Earth's largest terrestrial landslides. Basal cataclastic layers, injectites, pseudotachylyte, deformed clasts, and a variety of kinematic indicators demonstrate catastrophic emplacement, which was preceded by slow gravitational spreading of the volcanic field. This volume offers a history of their discovery, our current understanding of the gravity slides, and a guide to particularly instructive exposures for which the authors document their conclusions about the size, age, and significant structural features of these newly discovered features"--

The Geology of Quail Creek State Park

By: Robert F. Biek

The first thing most visitors to Quail Creek State Park notice, apart from the improbably blue and refreshing waters of the reservoir itself, are the brightly colored, layered rocks of the surrounding cliffs. In fact, Quail Creek State Park lies astride one of the most remarkable geologic features in southwestern Utah. The park lies cradled in the eroded core of the Virgin anticline, a long upwarp of folded rock that trends northeast through south-central Washington County. The fold is breached by erosion along its crest, creating a window into the geologic past.

Geologic Maps

What are You Standing On?

By: Robert F. Biek

Geologic maps: a few lucky geologists make them; many geoscientists, engineers, and planners use them; untold scores of people wonder what they are all about. Perhaps the most common question we are asked, those few of us who do make geologic maps, is, simply,“What is a geologic map?” This query is often followed by “What are geologic maps used for?,” “Hasn’t it been mapped before?,” and, if the person is really inquisitive, “What do all those lines, colors, and symbols represent?” It must be a puzzling sight - a lone geologist, often miles from the nearest road, looking at rocks, putting lines on a map or aerial photograph. One rightfully wonders what that person is doing. This pamphlet answers these questions and points out the value and many uses of geologic maps.
