The 20th edition to its popular geology series Down to Earth, the Arizona Geological Survey’s “A Guide to the Geology of Sedona Oak Creek, Arizona,” is now available from the agency’s online bookstore at www.azgs.az.gov, for $8.95.
The Arizona Geological Survey is one of those state agencies that few people know of.
It's no surprise given they are all about rocks and mines and things that go on beneath ground -- those things most of us never see.
But they are also about reaching out to citizens and visitors alike to help explain why Arizona's spectacular landscape looks the way it does and, occasionally, the dangers that come with it.
One of their more popular publications is a series called Down to Earth. Over the years the series has explained to the general public such things as diverse subjects as how geologists tell time, the geology of Flagstaff and a homebuyer's guide to geologic hazards.
This month AZGS has announced the publication of book number 20 in that series, "A Guide to the Geology of Sedona and Oak Creek Area, Arizona."
"It's our popular geology series. We write it for the general public. No expertise in geology is required to read and understand. And they are always well illustrated with lots of great graphics," says Mike Conway chief of the AZGS Geological Extension Service.
For $8.95, any layman, with a desire to understand the red rocks and how they came to be one of the nation's most famous geological formations, can become their own expert.
The book's author, John V. Bezy, tells the landscape's story through the descriptions of 24 distinct geological features, easily found while driving along area roadways.
Bezy explains how Sedona's sinkholes tell a story of subterranean caves why the off-white Coconino Sandstone lining Oak Creek Canyon is a remnant of 265 million year old sand dunes and how tinajas, small rock basins worn into bedrock drainages provide a critical source of water for wildlife, as well as humans.
Richly illustrated with 37 color photographs and six maps, the 40-page book is available through the Arizona Geological survey's Website, www. azgs.az.gov.
