River Valleys Observed By Viking Orbiters
The Viking Orbiters caused a revolution in our ideas about water on Mars. Huge river valleys were found in many areas. They showed that floods of water broke through dams, carved deep valleys, eroded grooves into bedrock, and traveled thousands of kilometers.

Famous quotes containing the words river, valleys, observed and/or viking:
“Every incident connected with the breaking up of the rivers and ponds and the settling of the weather is particularly interesting to us who live in a climate of so great extremes. When the warmer days come, they who dwell near the river hear the ice crack at night with a startling whoop as loud as artillery, as if its icy fetters were rent from end to end, and within a few days see it rapidly going out. So the alligator comes out of the mud with quakings of the earth.”
—Henry David Thoreau (1817–1862)
“It was a comfort in those succeeding days to sit up and contemplate the majestic panorama of mountains and valleys spread out below us and eat ham and hard boiled eggs while our spiritual natures reveled alternately in rainbows, thunderstorms, and peerless sunsets. Nothing helps scenery like ham and eggs.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“You have observed a skilful man reading Virgil. Well, that author is a thousand books to a thousand persons. Take the book into your two hands, and read your eyes out; you will never find what I find.”
—Ralph Waldo Emerson (1803–1882)
“Rice and peas fit into that category of dishes where two ordinary foods, combined together, ignite a pleasure far beyond the capacity of either of its parts alone. Like rhubarb and strawberries, apple pie and cheese, roast pork and sage, the two tastes and textures meld together into the sort of subtle transcendental oneness that we once fantasized would be our experience when we finally found the ideal mate.”
—John Thorne, U.S. cookbook writer. Simple Cooking, “Rice and Peas: A Preface with Recipes,” Viking Penguin (1987)
