How the Earth was made

Half Dome – Yosemite Musing

Yosey, as in Yosemite

We don’t have cable. Oh my, no cable TV at Mr. Half Dome’s cave?  We use a rooftop antenna and are happy with the 2 hours a week we watch. I get my cable fix at my health club.  I run the treadmill and stair-step to Discovery and the History channel.  Keeps me going to see the end of each show!  Yesterday, I caught a great show – “How the Earth was made.” I poked around and found that there is a whole series done by History. A few minutes of goggling showed that the History channel has a DVD box set on the series.  The show I saw was something that I have wanted for years – a baby-talk animation of earth’s formation from Day 0 to today. The deal of how water got formed, how the seas came about, where oxygen came from, the formation and subsequent break- up of Rodinia, the supercontinent, into Pangaea then Gondwanaland and Laurasia, the Global ice cap and melting. Whew. It all seems clear now.  Well, as part of the series, History is doing individual shows on major parts of the planet. They are rolling out a DVD on Yosemite. Apparently it is being broadcast now, but the DVD will be ready to ship on Jan 11.  Their website hope says: “The Sierra Nevada, North America’s highest mountain range, contains one of the most awe-inspiring geological features on the planet: Yosemite Valley . . . was it carved by gigantic glaciers or a cataclysmic rifting of the Earth?”  Hint: As John Muir said, Glaciers.

Unrelated thought worth quoting: “And laying his finger aside of his nose, and giving a nod, up the chimney he rose. He sprang to his sleigh, to his team gave a whistle, and away they all flew like the down of a thistle. But I heard him exclaim, ere he drove out of sight, Happy Christmas to all, and to all a good-night.” Clement Clarke Moore
