Anyone who stands at the rim of Grand Canyon is confronted with one of the most humbling spectacles
in the solar system, a high, featureless plateau interrupted by a mile-deep chasm. Its origin has been
controversial ever since John Wesley Powell?s historic navigation of the Colorado River in 1869. A long-held consensus is that the canyon is six million years old and was carved by the river. This lecture will examine data collected over the last three years suggesting instead that the canyon was incised between 70 and 80 million years ago, by a river flowing in the opposite direction to the modern Colorado River.

The Watson Lecture Series featuring prominent Caltech researchers is named for the late EARNEST C. WATSON, who founded the series in 1922. He presented one of his most popular lectures, ?Liquid Air,? as one of the first programs at the new Beckman Auditorium, a gift of Arnold O. and Mabel Beckman, in October 1964.

All lectures are held on Wednesdays at 8:00 p.m. in Beckman Auditorium, which is located near Michigan Ave., south of Del Mar Blvd. Through a gift from the estate of Richard C. Biedebach, the Watson Lecture Series has expanded to nine lectures annually. ADMISSION IS FREE.

Seating Information: A minimum of 700 seats is available on a free, no-ticket-required, first-come, first-served basis, beginning at 7:30 p.m. each lecture evening.
