Deep Time Quotes

“The Big Dipper wheels on its bowl. In years hence it will have stopped looking like a saucepan and will resemble a sugar scoop as the earth continues to wobble and the dipper’s seven stars speed in different directions.”

“Earth processes that seem trivially slow in human time can accomplish stunning work in geologic time. Let the Colorado River erode its bed by 1/100th of an inch each year (about the thickness of one of your fingernails.) Multiply it by six million years, and you’ve carved the Grand Canyon. Take the creeping pace of which the continents move (about two inches per year on average, or roughly as fast as your fingernails grow). Stretch that over thirty million years, and a continent will travel nearly 1,000 miles. Stretch that over a few billions years, and continents will have time to wander from the tropics to the poles and back, crunching together to assemble super-continents, break apart into new configurations- and do all of that again several times over. Deep time, it could be said, is Nature’s way of giving the Earth room for its history. The recognition of deep time might be geology’s paramount contribution to human knowledge.”

“I pace the shallow sea, walking the time between, reflecting on the type of fossil I’d like to be. I guess I’d like my bones to be replaced by some vivid chert, a red ulna or radius, or maybe preserved as the track of some lug-soled creature locked in the sandstone- how did it walk, what did it eat, and did it love sunshine?”

“Unkar Delta at Mile 73 The layers of brick red sandstone, siltstone, and mudstone of the Dox formation deposited a billion years ago, erode easily, giving the landscape an open, rolling character very different that the narrow, limestone walled canyon upstream, both in lithology and color, fully fitting Van Dyke’s description of “raspberry-red color, tempered with a what-not of mauve, heliotrope, and violet.” Sediments flowing in from the west formed deltas, floodplains, and tidal flats, which indurated into these fine-grained sedimentary rocks thinly laid deposits of a restful sea, lined with shadows as precise as the staves of a musical score, ribboned layers, an elegant alteration of quiet siltings and delicious lappings, crinkled water compressed, solidified, lithified.”
