Riordan Mansion Lunchtime Lecture: The Grand Canyon: Past and Present

Kevin Schindler of Lowell Observatory will share his recent project of rephotographing areas of the Grand Canyon and what has changed and what has stayed the same.

As part of his duties as Grand Canyon Astronomer in Residence in May 2023, Kevin Schindler of Lowell Observatory rephotographed areas in the Grand Canyon where Apollo astronauts trained in the 1960s. This repeat photography project expanded and grew into a book documenting how the Canyon and its natural and human-made features have changed – and in some cases remained startlingly the same – over the past century plus. Schindler will share many of these repeat images and also talk about some of the challenges of repeat photography.
