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!
Journal I : Expedition to Glacier Bay, Alaska, Summer 1890
Wed. Adams and I went to H with Plane Table and worked on the map. We staid [stayed] there until 9 pm. I made a sketch of the opening 3rd tributary. I also got a very pretty photograph of Mt. Casement with a Rock Basin lake in the foreground.
