For anybody interested in how beavers change landscapes, I can't recommend Ben Goldfarb's "Eager" highly enough. It made me a believer.
REALLY good book and made me think very differently about beavers. Highly recommend it!
Edit: The section of the book dedicated to European beavers is much smaller than the American counterpart, in case that matters. I do think the coverage was good on both sides though.
it was a heck of a trip though. I had a couple of up and down days but generally, it was a good one. It was my first hike, and it was a multi-day hike. So, in some ways I bit off more than I should've lol
Actually, I'd really recommend first just looking at all the pictures in the "pocket guide" version of the book. [2]
