"Bird's Eye View of a Continent"
This beautiful photography book is huge, and it is filled with aerial photos and satellite images of 100 locations. Each location includes a 2-4 page spread that gives a locator map, tips on spotting it from an airplane, and detailed geographical information, as well as full color photos. Important sights are covered; such as the Dinosaur National Monument in Utah and Colorado, and the Grand Canyon. But, many lesser known but equally important geological sights are included so any reader is sure to learn much new information.
I’d never heard of the Crater of Diamonds in Arkansas, where anyone can mine for diamonds. But, I would love to take my Minecrafting nephews and nieces there one day to do some real mining for real diamonds.
There are the extremes of the Uinta Mountains and the Great Salt Lake . There is the ethereal beauty of exquisite spots like Zion National Park, sitting halfway down the Grand Staircase in a canyon carved by the Virgin River. There is the colorful beauty of the ‘Pictured Rocks’ on the Great Lakes. Tiny Maine is surrounded by almost 4000 miles of coastline; so much so that it is home of over fifty lighthouses. Then there is Palo Duro, the ‘Grand Canyon of Texas.’ There is the Bay of Fundy with its semidiurnal tides.
The book describes Chaco Canyon with pueblos running north to south, aligned east to west to allow the native astronomers to track the sun’s equinoxes. It tells of the drowning of the Mississippi Delta, since the shores are so tightly controlled all along the Mississippi now by the US Army Engineers that the delta loses land every day. Lost land would have provided more of a buffer from Hurricane Katrina in Mark Twain’s time. Man battles to control the sea, and loses on one end or the other. Save lives here to lose them there.
There’s the natural marvels; like Utah’s Rainbow Bridge and New Mexico’s Ship Rock. Devils Tower juts up from the flatlands of Wyoming, visible for miles around. The Spanish Peaks lying between the Sangre de Cristo Mountains in New Mexico and the Colorado Rockies formed by a couple of volcanic intrusions underground. As a result, they are surrounded by dikes of igneous rock, some higher than 100 feet. While the surrounding sedimentary rocks erode from wind and rain, the volcanic rock stands solid, unbending.
Morton gives basic information on important mountain climbing locations throughout. She gives the location of ‘fourteeners’ (mountain peaks that exceed 14,000 feet) across the continent, and mentions aspects of technical climbing vs. amateur climbs. Geologic activity and formations are covered; like quiet quakes, maars, dikes, laccoliths, plugs, stocks, and sills from underground eruptions.
The book covers people living in oft devastated regions, like the Outer Banks of North Carolina. Native ancestral Puebloans hollowed out Cliffside cave dwellings in the pyroclastic deposits of a supervolcanic eruption that collapsed at Valles Caldera.
Much history comes through; like the tragic story of Canyon De Chelly’s native massacres in Arizona, and man-made carvings in the rocks, like Mount Rushmore and the Confederate Generals on Stone Mountain in Atlanta. Native population origins are described; such as ancient cultures displaced by the Apache, who were in turn displaced by the Comanche and the Kiowa… who were in turn displaced by the US government.
This picturesque work covers a variety of the visible natural wonders across the North American continent. There are the Sweeping Saint Anthony Sand Dunes juxtaposed on the landscape of Idaho, The White Sands New Mexico gypsum deposits. Great Sand Dunes stacked against the Sangre de Cristo Mountains, a southern range of the Rockies. And, it illustrates how dunes form in different shapes: dome, crescent, parabolic, transverse, star dunes, reversing dunes, barchan, and nebkha or coppice dunes. The author explains how Medano Creek carries sediments blown into the mountains back to the dune field, playing an important role in continuing the cycle of dune building.
Morton shares much of the wild beauty of Utah: from the red, pink, yellow, orange, and white sandstone of ‘Red Rock Country’ in Canyonlands National Park, to the Gooseneck of San Juan River to the Grand Staircase that descends across Southern Utah down into the Grand Canyon. But, a locator map shows how the 100 locations covered are spread across the North American continent.
I enjoyed the huge hardbound edition I found at Barnes & Noble. I highly recommend this beautiful work done by Mary Caperton Morton. She travels the continent writing about geological topics in travel books, magazines, and in her blog, The Blond Coyote.
