This a video I put together using a panoramic repeat photo pair that I made last summer in Denali National Park and Preserve, Alaska. The pair shows 95 years of change of the Polycrome Glaciers and the Alaska Range in Denali NP.

Here’s a sneak peek of one of the repeat photo pairs I created earlier this summer in Denali National Park, Alaska during my fieldwork for my Murie Science and Learning Center Fellowship S.R. Capps Project:

This summer I’m beginning work on a project reconstructing and mapping the 1916 and 1919 scientific field investigations of U.S. Geological Survey geologist Stephen Reid Capps in the Denali National Park and Preserve area of Alaska.

Stephen Reid Capps faced significant challenges traveling and conducting geology fieldwork in remote Alaska in 1915. Travel throughout Alaska at the beginning of the 20th century was limited by the general lack of road and rail infrastructure and typically required travel by foot, horse, dogsled, or boat.

For the 1915 summer field season, two USGS parties were deployed to the Turnagain Arm and Knik Arm region of Alaska. James W. Bagley led the topographic survey and Stephen Reid Capps led the geologic investigation.
