Roadside Geology of Texas
The geologic panorama of Texas is as wide as the state is big, sweeping from volcanic mesas and thrusting mountains in the west to the red canyons of the Panhandle, along tropical sand barriers of the Gulf Coast, and across central limestone plateaus to the hard granitic terrain of central 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 Oregon
Until about 200 million years ago, the western margin of North America lay to the east, along the present Idaho border, and a broad coastal plain spread westward into Oregon. The rest of the state was ocean floor. Then the continent began moving slowly westward away from Europe and the floor of the Pacific Ocean began sliding beneath the western edge. That is what created Oregon, and this book tells how it happened.
Roadside Geology of Montana
Montana's geologic history includes a long succession of disturbances that changed the rocks, then changed many of them again. Unraveling these events reveals a geologically quiet continent that got scrambled in a long and grinding collision with the Pacific crustal plate. Through detailed geologic maps and lively text, Roadside Geology of Montana deciphers the complicated rock record and uncovers each layer of Big Sky Country.
Roadside Geology of Washington
The geology of Washington is a story of islands-- micro-continents-- coming in from the sea. Two hundred million years ago most of Washington consisted of two large islands, each one a scrap of continent, lying somewhere in the vastness of the Pacific Ocean. One after the other they docked onto the North American continent, each adding its distinctive bit to the complex geologic and geographic mosaic of western North America.
Geology Underfoot in Southern California
Reading the rocks like pages in a book, Geology Underfoot in Southern California offers an inside view of the southland's active and sometimes enigmatic landscape. Twenty vignettes each weave a geologic story of a particular scene, relationship, or feature. Some spotlight well-known landmarks, while others describe subtle relationships among the earth's awesome forces. Together these snapshots introduce readers to southern California's rich, dynamic, and even flamboyant geology.
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
