In 1890 & 1892, Harry Fielding Reid traveled to Glacier Bay, Alaska. During the expedition, Reid mapped Glacier Bay, collaborated with John Muir, measured the movement of the glaciers, created sketches and made photographs of the glaciers, and produced 24 notebooks.
The National Snow and Ice Data Center (NSIDC) has transcribed these expedition notebooks, so you can follow along with Reid's expeditions and experience Glacier Bay as he saw it over 100 years ago!
