This remarkable image sequence captures a series of massive calving events at Columbia Glacier near Valdez, Alaska. Composed of 436 frames taken between May and September of 2007, it shows the glacier rapidly retreating by about half a mile (1.6 kilometers), a volume loss of some 0.4 cubic miles (1.67 cubic kilometers) of ice or 400 billion gallons (1.5 trillion liters) of water.
"A stunning survey of the latest evidence for intelligent life on Mars. Mac Tonnies brings a thoughtful, balanced and highly accessible approach to one of the most fascinating enigmas of our time."
--Herbie Brennan, author of Martian Genesis and The Atlantis Enigma
"Tonnies drops all predetermined opinions about Mars, and asks us to do the same."
--Greg Bishop, author of Project Beta
"I highly recommend the book for anyone interested in the search for extra-terrestrial artifacts, and the political intrigues that invariably accompany it."
--David Jinks, author of The Monkey and the Tetrahredron
"Mac Tonnies goes where NASA fears to tread and he goes first class."
--Peter Gersten, former Director of Citizens Against UFO Secrecy

I teach mountaineering up in the alaskan mountains, and I've spent a lot of time in the Chugatch and I've been on the Columbia Glacier (shown in this video)
It's a weird thing to see.
Melting ice is hard to wrap your mind around. but the realities are creepy.
You hold a map in your hand, and it shows glacial ice, but you are standing on rocky moraine (that's what its called after a glacier retreats) but the map isn't that old.
pray for our fragile planet.
My God, the horror! I can't bel.....Oh look, monkeys riding little motorbikes!
