The most complete work published on the natural history of southwest Colorado's majestic mountain system, The Western San Juan Mountains: Their Geology, Ecology, and Human History is designed to be used while exploring the scenic 235-mile paved San Juan Skyway, which passes through Durango, Silverton, Ouray, Telluride, Dolores, and Cortez.

The Western San Juan Mountains covers the physical environment, the biological communities, the human history, and points of interest represented on milepost signs along the highway. Some of the many topics covered include: how the San Juan Mountains were formed; why the landscape is so rugged and picturesque; why the vegetation changes from the lowlands to the alpine heights; energy and mineral resources of the area; why these mountains intrigued early explorers; factors that influence the unpredictable weather; and the first-known inhabitants.

The contributions to this guide include Fort Lewis College geologists, biologists, archaeologists, historians, and other specialists. Together they have amassed more than one hundred years of study based not only on previous work but on their own research.

This generously illustrated guidebook is aimed at all those who wish to understand this intricate mountain system in much greater detail than provided by most picture books.

Did you know that Benjamin Franklin examined the first dinosaur bone in America from Woodbury, Gloucester County, in 1787--decades before the word dinosaur was even coined? Or that when the first reasonably complete dinosaur skeleton in the world was unearthed in Haddonfield, Camden County, in 1858, it was a major scientific breakthrough which forced paleontologists to completely revise their picture of dinosaur anatomy? Few people know that New Jersey is the nursery of American vertebrate paleontology!

When Dinosaurs Roamed New Jersey provides a succinct and readable history of the geology and paleontology of New Jersey from the time the region was covered by Cambrian seas, 543 million years ago, to the Pleistocene Ice Age only 10-15,000 years ago. William Gallagher tells the stories of professional and amateur fossil hunters, their discoveries, and their impact on the history of paleontological thought. He points out places in New Jersey and nearby where specimens characteristic of each era were found. He shows how fossil evidence found in the state is helping paleontologists uncover the ecological interactions and behavior of dinosaurs, and discusses such ongoing scientific controversies as the reason for the extinction of the dinosaurs.

From tracking dinosaur footprints across the Newark basin, to digging for the last dinosaurs in the greensands of South Jersey, to finding a mushroom in ancient amber in East Brunswick, this book is the ideal introduction to the Garden State's fossils and prehistory.

Far from being the serene, natural streams of yore, modern rivers have been diverted, dammed, dumped in, and dried up, all in efforts to harness their power for human needs. But these rivers have also undergone environmental change. The old adage says you can’t step in the same river twice, and Ellen Wohl would agree—natural and synthetic change are so rapid on the world’s great waterways that rivers are transforming and disappearing right before our eyes.

            A World of Rivers explores the confluence of human and environmental change on ten of the great rivers of the world. Ranging from the Murray-Darling in Australia and the Yellow River in China to Central Europe’s Danube and the United States’ Mississippi, the book journeys down the most important rivers in all corners of the globe. Wohl shows us how pollution, such as in the Ganges and in the Ob of Siberia, has affected biodiversity in the water. But rivers are also resilient, and Wohl stresses the importance of conservation and restoration to help reverse the effects of human carelessness and hubris.

            What all these diverse rivers share is a critical role in shaping surrounding landscapes and biological communities, and Wohl’s book ultimately makes a strong case for the need to steward positive change in the world’s great rivers.
