Grant Collier has been following—literally—in the footsteps of his great-great-grandfather, the pioneer photographer Joseph Collier. He has traveled throughout Colorado taking photographs from the exact same spots where Joseph captured his images over a century before. Grant released his first book of images from this project, Colorado: Yesterday & Today, in 2001. He recently released a sequel to that book, Colorado Then & Now. Grant will present a slideshow of images from this new book, and will discuss the challenges both he and Joseph Collier faced when capturing these images. He’ll explain the history behind many of the images while discussing both successful and unsuccessful attempts at historic preservation throughout the state.
