I dug out the sources/references for the John Muir quotes I have on my blog.
Because it's fun digging around in old digitally archived books online.
First, a nice pic of John Muir:
QUOTE: “The mountains are calling and I must go.”

QUOTE: “The power of imagination makes us infinite.”

How did I find it?
(Sometimes that works. Sometimes it doesn't.)
