Encyclopedia Britannica Online

When I was kid, I was fascinated by the huge Encyclopedia Britannica books. Who were these amazing eggheads that wrote all the world’s information down? How did they get so smart?

Times change. The Encyclopedia Britannica still has the most vetted information, but is no longer the largest or easiest accessible. They’ve offered to bloggers, though, the opportunity to search their tomes for free, and even better, and article I link to is completely available to all the Chasing the Wind readers. I’m going to give it a try, and look up information on the Grand Canyon:

The Grand Canyon lies in the southwestern portion of the Colorado Plateau, which is a large area of the southwestern United States consisting essentially of horizontal, layered rocks and lava flows. The broad, intricately sculptured chasm of the canyon contains between its outer walls a multitude of imposing peaks, buttes, gorges, and ravines. It ranges in width from about 0.1 to 18 miles (0.2 to 29 km) and extends in a winding course from the mouth of the Paria River, near Lees Ferry and the northern boundary of Arizona, to Grand Wash Cliffs, near the Nevada line, a distance of about 277 miles (446 km). Its greatest depths lie more than a mile (some 6,000 feet [1,800 metres]) below its rim. The canyon includes many tributary side canyons and surrounding plateaus. The deepest and most impressively beautiful section, 56 miles (90 km) long, is within the central part of Grand Canyon National Park, which encompasses the river’s length from Lake Powell (formed by Glen Canyon Dam in 1963) to Lake Mead (formed by Hoover Dam in 1936). In its general colour, the canyon is red, but each stratum or group of strata has a distinctive hue—buff and gray, delicate green and pink, and, in its depths, brown, slate-gray, and violet. At approximately 8,200 feet (2,500 metres) above sea level, the North Rim is some 1,200 feet (3,658 metres) higher than the South Rim.

Hey, pretty spiffy. Can you click the link for the Grand Canyon and tell me if you can read the whole article?
