Just finished – it took two months as it’s quite a tedious read – Douglas Brinkley’s The Quiet World: Saving Alaska’s Wilderness Kingdom.
While it focuses on Alaska, it provides great background and insight into the names we all know: John Muir, Bob Marshall, William O Douglas and a bunch I’d never heard of before. All of whom played significant roles in saving not only Alaska, but the lower forty eight as well.
If you’re really interested in conservation this is “must read.” By the way, this is the second book of the three planned by Brinkley on the history conservation in America.
