This video from the USA says about itself:
Tueeulala Falls – Hetch Hetchy – Yosemite National Park
John Muir described Tueeulala Falls in Hetch Hetchy as “descending like thistledown.” Watch this beautiful waterfall, while listening to Muir’s poetic description, read by Restore Hetch Hetchy Executive Director Ron Good.
From the Sierra Club in the USA:
The newest digital collection at the University of the Pacific’s library will excite any John Muir enthusiast. The library has scanned more than 6,500 of his letters and posted them online.
Reading through the letters will give you glimpses into his personal life and conservation efforts, including his founding of the Sierra Club. The letters are both handwritten and typed. The handwritten ones are more fun to read, though, because you get to see his beautiful, fluid penmanship.
