Roadside Geology of Minnesota
You may have heard that Minnesota’s ten thousand lakes are the hoofprints of Paul Bunyan’s big blue ox, Babe. “Don’t you believe it!” writes author Dick Ojakangas. Though the lakes, which formed at the end of the most recent ice age, may be Minnesota’s most famous features, the glaciated countryside disguises a much longer history of volcanoes and plate collisions—not surprising when you learn that Minnesota was at the active edge of the fledgling North American continent for several billion years.
Roadside Geology of Minnesota steers you over glacial moraines and till plains to some of the state’s unparalleled geologic features, such as the Morton Gneiss, once thought to be the oldest rock on Earth; the St. Peter Sandstone, one of the purest sandstones
in the world; the banded iron-formation, the source of iron for the Great Lakes steel industry; and the ancient shorelines of Glacial Lake Agassiz, one of the largest glacial lakes ever to have existed in North America. The book’s introduction presents an overview of Minnesota’s geologic history, and forty-two road guides discuss the landforms and rocks visible from a car window and at nearby waysides and parks, including Pipestone National Monument, Grand Portage National Monument, and Voyageurs National Park. Richard W. Ojakangas. 398 pgs., 6 x 9, paperback

Roadside Geology of Arizona
The rise of mountains and the spread of deserts has marked the geologic history of Arizona. Landscapes that we see today are here because of landscapes of the past, and because of tremendous forces deep within the earth, forces that carry continents into collisions and then drag them apart again, forces of heat and pressure and the slow churning boil of the earth's interior. Landscape features result, too, from more comprehensible, more recent forces: the unending attack of water and wind and frost, the building of volcanoes, the short-term geologic happenings like landslides and rockfalls, earthquakes and floods, and a gopher digging a hole...
Roadside Geology of Hawaii
Roadside Geology of Hawai`i details the evolution of this volcanic island chain, from the origin of a hot spot and the tumultuous creation of each island to ongoing eruptions and the gradual death and erosion of old volcanoes. Residents and tourists alike will soon become experts on lava tubes and lava flows, ancient beaches and coral reefs, ephemeral black sand beaches and the occasional tsunami. Includes a chapter each on six easily accessible and populated islands: Hawai`i , Maui, Lana`i, Moloka`i, O`ahu, and Kaua`i. Each chapter begins with a general discussion of the rocks of that island, then proceeds with a seres of road guides that provide the local details.
Roadside Geology of Ohio
Ohio's bedrock reveals a rich story of the ancient landscapes and animals-foot-long clams, massive meat-eating reptiles, lumbering mammoths-that existed thousands to hundreds of millios of years ago. Fluctuating seas full of marine life, widespread floodplains and rivers choked with sediment, and mile-thick ice sheets from the north all shaped Ohio's present landscape. But Ohio's geologic tale has a human side too. Native Americans fashioned razor-sharp flint spear points; oil, gas, and coal fueled several economic booms; sandstone and limestone built communities and thriving economies.
The 25 road guides of Roadside Geology of Ohio, complete with 59 maps and figures and 172 photographs, lead you from one corner of the state to the other-from the flat till plains of the west to the hilly eastern Allegheny Plateau, and from the Ohio River valley to the Lake Erie shoreline. Mark Camp's clear writing explains how caverns and disappearing streams for in karst; why mud cracks, ripple marks, and cross-bedding layers are entombed in sedimentary rock; and how grooves up to 10 feet deep were gouged into the limestone of Kelleys Island. From deserted boomtowns to Ohio's big cities, Roadside Geology of Ohio thoroughly reveals the Buckey State's fascinating and dynamic geology.

Roadside Geology of Texas

Learn about the rocks as you come to them - what they are, when they formed, what they mean, and how they fit into the big picture of the geology of Texas.
Roadside Geology of the Yellowstone Country, 2nd Edition
With more than 10,000 geysers, hot springs, fumaroles, and mud pots, as well as cubic mile upon cubic mile of once-incendiary rhyolite, the landscape of Yellowstone Country vividly displays its fiery past and present. The region contains 1/5 of the world’s geysers, including the most famous of them all, and is the setting of some of Earth’s most destructive volcanic eruptions. The 19 road guides in Roadside Geology of Yellowstone Country fully explore this volcanic pedigree while also delivering you to sites that have recorded the region’s broad and deep geologic story, which includes exquisitely preserved, 50-million-year-old petrified trees buried in conglomerate; mountain-sized blocks of rock that slid more than 50 miles in a massive debris avalanche; the glacially carved craggy peaks and U-shaped valleys of the Beartooth Mountains and Absaroka Range; and the Grand Canyon of the Yellowstone, the excavation of which is still a mystery. This completely revised second edition reexamines the region using the latest scientific thinking and now includes stunning full-color photos, maps, and diagrams.
