Around 13,000 years ago, three things happened at once: (1) Global temperature suddenly stopped rising and plunged back to ice age-frigidity. (2) The Western Hemisphere’s largest mammals, including the horse, camel, woolly mammoth, saber-toothed cat, and dozens more, went extinct. And (3) the uniquely beautiful stonework of the early American Clovis people disappeared from the archeological record. For the past half-century, scientists have struggled to explain the three events. Were they independent of each other, or could they have had a common cause?

From late 1872 to 1876, H.M.S. Challenger explored the world's oceans. Conducting deep sea soundings, dredging the ocean floor, recording temperatures, observing weather, and collecting biological samples, the expedition laid the foundations for modern oceanography. Following the ship's naturalists and their discoveries, earth scientist Doug Macdougall engagingly tells a story of Victorian-era adventure and ties these early explorations to the growth of modern scientific fields.

Joe Tasker lies, struck down by illness, in a damp, bug-infested room in the Himalaya, wondering if he will be well enough to climb Dunagiri, his first venture to the "big" mountains. One of Britain’s foremost mountaineers and a pioneer of lightweight climbing, he is about to attempt one of the first true "Alpine-style" climbs in the Greater Ranges. The Dunagiri attempt forms part of Tasker’s striking tale of adventure in the savage arena of the mountains.

Published to coincide with the centenary of the first expeditions to reach the South Pole, An Empire of Ice presents a fascinating new take on Antarctic exploration. Retold with added information, it's the first book to place the famed voyages of Norwegian explorer Roald Amundsen, his British rivals Robert Scott and Ernest Shackleton, and others in a larger scientific, social, and geopolitical context.

In this poetic personal narrative, Thomas P. Huber reflects on two seemingly unrelated places—the North Fork Valley in western Colorado and the Coulon River Valley in Provence, France—and finds a shared landscape and sense of place. What began as a simple comparison of two like places in distant locations turned into a more complex, interesting, and personal task. Much is similar: the light, the valleys, the climate, the agriculture. And much is less so: the history, the geology, the physical makeup of villages.
