150 Years of Change: How Old Photos, Recaptured, Reveal a Shifting Climate
Briefly

A group of scientists and adventurers journey into the Uinta Mountains to replicate 1870s photographs by William Henry Jackson. This re-photography project aims to elucidate environmental changes over time, such as alpine shifts and glacial retreat. Challenges arise in pinpointing original locations due to changing place names and descriptions, along with equipment variations and rugged terrain. By exploring the same landscapes as Jackson, the team hopes to uncover historical shifts that are crucial for understanding current ecological trends.
The process known as re-photography involves capturing the same scene from the same location after a span of time and is essential to track long-term environmental changes.
Finding the original location is challenging due to changing place names and descriptions, making re-photography both rewarding and complex for researchers.
Subtle variations in photographic equipment over time can complicate matching images for re-photography, alongside terrain challenges like rockslides and erosion.
We will be hiking and replicating historical photography to study environmental changes in the Uinta Mountains, echoing the efforts of pioneers like Jackson.
