Gretchen Sorin recovers a forgotten history of black motorists, and recounts their creation of a parallel, unseen world of travel guides, black only hotels, and informal communications networks that kept black drivers safe. At the heart of this story is Victor and Alma Green's famous Green Book, begun in 1936, which made possible that most basic American right, the family vacation, and encouraged a new method of resisting oppression.

The Space Age began just as the struggle for civil rights forced Americans to confront the long and bitter legacy of slavery, discrimination, and violence against African Americans. Presidents John F. Kennedy and Lyndon Johnson utilized the space program as an agent for social change, using federal equal employment opportunity laws to open workplaces at NASA and NASA contractors to African Americans while creating thousands of research and technology jobs in the Deep South to ameliorate poverty.

North America was not empty nor were its inhabitants savages when Europeans arrived in 1492. Quite the opposite, North America was thickly populated by indigenous people who lived in clean cities, had a thriving economy, and transformed the landscape into bountiful productivity. Forgotten Landscapes reveals the incredible extent to which Native Americans manipulated and shaped their surrounding environs through agricultural practices and urban engineering, resulting in one of the most prosperous civilizations of their time.

The Great Lakes are graveyards of a vast number of shipwrecks (30,000 by some estimates), and Lake Michigan has more than the other four lakes combined. The stories of those wrecks tell the history of that mighty lake in its endless, mercurial challenge to human endeavor.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

From the colonial era through the mid-twentieth century, America's flocks played a key role in the nation's development. Furthermore, much consternation centered around the sheep the United States lacked, so that dependency on foreign wool became a full-blown crisis in wartime. But more than just providers of wool, sheep were valued for their meat, for their byproducts after slaughter, and even for their efficiency at lawn maintenance.

Old Victoria, a ghost town from the copper boom, shows what life was like homesteading in Michigan's Upper Peninsula. Over the years, some of the site has been destroyed or has collapsed; still, many of Old Victoria's original homesteads remain standing. Thanks to the efforts of a local group, The Society for the Restoration of Old Victoria, quite a few of the buildings have been restored and refurnished in their original condition.

The naturalist, author, and advocate for preservation, John Muir (1838-1914) was also known as "John of the Mountains" and "Father of the National Parks". In the spring of 1869, John Muir was looking for ways to fund his explorations of California’s Central Valley region, when a ranch owner offered him a job herding sheep in the Sierra Nevada. In The Yosemite, Muir chronicled his experiences of the beautiful wilderness in appealingly descriptive prose. The audiobook is a treasure trove of portrayals of the shifting phases of the year in Yosemite.

On February 22, 1978, a devastating freight train derailment drastically altered Waverly, Tennessee, and its place in history. This was one of the worst train explosions of the twentieth century, killing sixteen people, injuring hundreds more, and causing millions of dollars in damage. What could have been dismissed as a single community's terrible misfortune instead became the catalyst for radical change, including the formation of FEMA, much-needed reforms in emergency response training, and the creation and enforcement of national and state safety regulations.

In this fresh and powerful work of environmental history, Martin Doyle explores how rivers have often been the source of arguments at the heart of the American experiment - over federalism, taxation, regulation, conservation, and development. Doyle tells the epic story of America and its rivers, from the US Constitution's roots in interstate river navigation, the origins of the Army Corps of Engineers, the discovery of gold in 1848, and the construction of the Hoover Dam and the TVA during the New Deal, to the failure of the levees in Hurricane Katrina.

The incredible, untold story of the men who risked their lives in the first transcontinental air contest—and put American aviation on the map.

From 1754 to 1755, the slave ship Hare completed a journey from Newport, Rhode Island, to Sierra Leone and back to the United States - a journey that transformed more than 70 Africans into commodities, condemning some to death and the rest to a life of bondage in North America. In this engaging narrative, Sean Kelley painstakingly reconstructs this tumultuous voyage, detailing everything from the identities of the captain and crew to their wild encounters with inclement weather, slave traders, and near-mutiny.

The Tensaw River introduces one of the American South's richest and most fertile natural features. Author Mike Bunn is director of Historic Blakeley State Park, which is nestled in a prominent bend of the majestic Tensaw River.

Countering the conventional narrative that Florida's tourism industry suffered during the Great Depression, this book shows that the 1930s were the starting point for much that characterizes modern Florida's tourism. David Nelson argues that state and federal government programs designed to reboot the economy during this decade are crucial to understanding the state today.

The chilling tome that launched an entire genre of books about the often gruesome but always tragic ways people have died in our national parks, this updated edition of the classic includes calamities in Yellowstone from the past sixteen years, including the infamous grizzly bear attacks in the summer of 2011 as well as a fatal hot springs accident in 2000. In these accounts, written with sensitivity as cautionary tales about what to do and what not to do in one of our wildest national parks, Whittlesey recounts deaths ranging from tragedy to folly.

From 1907 to 1967, a network of reservoirs and aqueducts was built across more than one million acres in upstate New York, including Greene, Delaware, Sullivan, and Ulster Counties. This feat of engineering served to meet New York City's ever-increasing need for water, sustaining its inhabitants and cementing it as a center of industry. West of the Hudson, it meant that twenty-six villages, with their farms, forest lands, orchards, and quarries, were bought for a fraction of their value, demolished, and submerged, profoundly altering ecosystems in ways we will never fully appreciate.
