Epic Hikes of the World ( PDFDrive )

For geologists, there’s no place on earth like the Grand Canyon. Nearly two
billion years of the planet’s history are encapsulated in the canyon’s milehigh
jumble of fossil-laden rock layers, allowing scientists to take a
mesmerising walk back through time.
Alas, science was never really my thing. Even the simplest paragraph in a madefor-dummies
textbook went in one ear and out the other. Still, universities have their
expectations, and mine wanted me to complete three science classes before
graduation. So when I saw ‘Geology of the Grand Canyon’ listed among the
autumn course options during my sophomore year at Stanford, it was like manna
from heaven.
