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
Wednesday Thursday. Today we spent in camp, doing nothing but resting; Prof Muir leaves us tomorrow so I have given him all the points I could as to the location and distance of various mountains and trib. glaciers. He also gave me information regarding the Main [Muir?] Lake and its valley. Mr. Cushing, Adams and Prof. Muir, spent a day down the inlet during our absence and had a good time.
