John Muir's cabin in Glacier Bay

I knew Harry Reid was old, but this is ridiculous! 

From July to September 1890 John Muir and his friends toured Glacier Bay. Dr. Henry Platt Cushing did the meteorological, geologic and botanical studies on the trip. He was a prominent geologist who taught at Western Reserve University . He was joined by his collegue Dr. Henry Fielding Reid of the Case School of Applied Science in Cleveland, Ohio. (Today these two universities are combined to be Case Western Reserve University).
Their students were:

Comfort Avery Adams, who had just graduated from Western University with a degree in mechanical engineering and later taught at Harvard for 45 years in electrical engineering.
R.L. Casement of Plainesville, Ohio.
Mr. James H. McBride later physician at CalTech.
John F. Morse (presumably taking the photo) who later was a physician in San Francisco, but died at the age of 40 in 1898 there.

In 1890 Muir’s health was poor and he suffered from snow blindness. He expressed irritation with the “stream of tourists habitually snapping their Kodaks and asking naive questions, and with the haste at which they ceased gazing at glaciers whenever a dinner bell sounded.” However, like many tourists today, Muir returned to Glacier Bay in 1899. All of his friends later had glaciers named for them.
