Ancient Landscapes of Western North America
Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section
Rough-Water Man
The passage of the 1902 Reclamation Act created a mandate for the federal government to build dams on the Colorado River and its powerful tributaries. By 1920 the US Geological Survey had surveyed the river’s main courses, but still needed accurate charts of the last stretches of deep canyons and white-water rapids, accessible only by boat.Rough-Water Man is the first detailed account of these mapping expeditions by the USGS—the San Juan Canyon in 1921, the upper Green River in 1922, and the Grand Canyon in 1923. Illustrated throughout with period photographs, it is also the personal story of twenty-four-year-old Henry Elwyn Blake Jr., the only boatman to crew on each of the three trips,...

Grand Canyon
Arizona Highways assembled a photographer and two writers, asking each to apply his specialty in relating the Grand Canyon's physical and metaphysical qualities. Their encounters with the Canyon embody decades of experience, and their previous works have garnered awards. The result combines journalistic and impressionistic descriptions, both in words and in photographs.
The Grand Canyon
-Could the Grand Canyon's rock layers have formed in a single year of Noah's flood?-Why are there no dinosaur, bird or mammal fossils in the canyon's layers?-How do we know that radiometric dating methods are reliable?-How can we tell what happened in the unobserved past?-How long did it take to carve out the canyon?-Is Young Earth Creationism really biblical?Learn the answers to these questions and more to understand how the Grand Canyon testifies to an old earth. Insights from top geologists, highlighted by stunning photographs, provide a memorable guide to these ancient wonders of creation.
