Ashworth takes us across the Great Lakes, blending history and geology with a first-person narrative to describe the absolute beauty of the scenery on North America's Fifth Coast. The first quarter of the book or so talks about the discovery of the Great Lakes by Europeans and their subsequent drive to tame the vast waters, use them for commerce and ultimately exploit their resources and navigation channels for a new nation. First it was fur, then trees, then metal, each industry ravishing the landscape in a different way.
What remains constant is the underlying truth of these Lakes' existence: they're geologically infant and therefore fragile to human whims. especially whims that aren't well thought out, or at least ignorant of the instability of the waters. This is a great companion to Dan Egan's Death and Life of the Great Lakes published last year, covering many of the same topics from invasive species to navigation to algal blooms to acid rain. We make drastic decisions about our Lakes without thinking ahead, not knowing the bigger picture, or just not caring. If we're not careful, with responsible management, the Great Lakes may eventually be destroyed (in the case of pollution and invasive species and dredging) or simply taken away (piped to the Ogallala region).
