“Three hundred types of mussel, a third of the world’s total, live in the Smokies. Smokies mussels have terrific names, like purple wartyback, shiny pigtoe, and monkeyface pearlymussel. Unfortunately, that is where all interest in them ends. Because they are so little regarded, even by naturalists, mussels have vanished at an exceptional rate. Nearly half of all Smokies mussels species are endangered; twelve are thought to be extinct.This ought to be a little surprising in a national park. I mean it’s not as if mussels are flinging themselves under the wheels of passing cars. Still, the Smokies seem to be in the process of losing most of their mussels. The National Park Service actually has something of a tradition of making things extinct. Bryce Canyon National Park is perhaps the most interesting-certainly the most striking-example. It was founded in 1923 and in less than half a century under the Park Service’s stewardship lost seven species of mammal-the white-tailed jackrabbit, prairie dog, pronghorn antelope, flying squirrel, beaver, red fox, and spotted skunk. Quite an achievement when you consider that these animals had survived in Bryce Canyon for tens of millions of years before the Park Service took an interest in them. Altogether, forty-two species of mammal have disappeared from America's national parks this century.”

“Building a museum case and filling it with types of mussels is one way of knowing mussels; but on the shore, a mussel leads to a crab or a curious stone, which leads to another thing and eventually leads back to mussels, which is another and perhaps a more far-reaching way to know mussels. The sea that always seems like a metaphor, but one that is always moving, cannot be fixed, like a heart that is a like a tongue that is like a mystery that is like a story that is like a border that is like something altogether different and like everything at once. One thing leads to another, and this is the treasure that always runs through your fingers and never runs out.”

“There is nothing so American as our national parks. The scenery and the wildlife are native. The fundamental idea behind the parks is native. It is, in brief, that the country belongs to the people, that it is in process of making for the enrichment of the lives of all of us. The parks stand as the outward symbal of the great human principle.”

“Yellowstone National Park is no more representative of America than is Disneyland.”

“At the foot of the mountain, the park ended and suddenly all was squalor again. I was once more struck by this strange compartmentalization that goes on in America -- a belief that no commercial activities must be allowed inside the park, but permitting unrestrained development outside, even though the landscape there may be just as outstanding. America has never quite grasped that you can live in a place without making it ugly, that beauty doesn't have to be confined behind fences, as if a national park were a sort of zoo for nature.”
