John Muir is known as “John of the Mountains” and “Father of the National Parks.” He was a naturalist, an advocate for the preservation of our country’s wilderness, a writer, philosopher, and a pioneer of our national park system. “The Mountains Are Calling and I Must Go.”
“The world is big and I want to have a good look at it before it gets dark.”
“How glorious a greeting the sun gives the mountains!” 
Wherever we go in the mountains, or indeed in any of God’s wild fields, we find more than we seek.” 
“Everybody needs beauty as well as bread, places to play in and pray in, where nature may heal and give strength to body and soul.” 
“This grand show is eternal. It is always sunrise somewhere; the dew is never all dried at once; a shower is forever falling; vapor ever rising.” 
“Come to the woods, for here is rest. There is no repose like that of the green deep woods. Sleep in forgetfulness of all ill.” 
“When one tugs at a single thing in nature, he finds it attached to the rest of the world.” 
” I never saw a discontented tree.” 
“We are now in the mountains and they are in us, kindling enthusiasm, making every nerve quiver, filling every pore and cell of us.” 
“Oh, these vast, calm, measureless mountain days, days in whose light everything seems equally divine, opening a thousand windows to show us God.”
