I posted this earlier.
But in case you missed it, and never saw the episode, I highly recommend it. Plus it’s part of a 26-episode high-resolution uploading of the entire series How The Earth Was Made by the History Channel themselves. So far they’ve uploaded 24 of the 26, with the remaining episodes, New York and Yosemite Park still to come. They upload 1 each week at around 10PM EST. These are of excellent quality, averaging out at about 900MB per 1 hour episode! So grab em while you can, if you like this stuff.

...forgot to mention, the weekly uploads are on Fridays, at ~10PM EST. Only two more to go. The rest are all up on the site and should be accessible through the link I provided above, or by going to the History Channel’s YouTube channel and searching for the series there.
