If anything is endemic to Wyoming it is wind. This big room of space is swept out daily, leaving a bone yard of fossils, agates, and carcasses in every stage of decay. Though it was water that initially shaped the state, wind is the meticulous gardener, raising dust and pruning the sage.

To trace the history of a river . . . is to trace the history of the soul, the history of the mind descending and arising in the body.

There was not one cause for our internment, but many - a deep-seated racial prejudice working on top of fear, distrust, and greed. So how is one to say exactly where history begins or ends? It is all slow oscillations, curves, and waves which take so long to reveal themselves ... like watching a tree grow.

A black-crowned night heron stood on an apron of wet sand, looking across the channel. The feather plume at the back of his head lifted in a faint breeze. Out there the channel churned its cyclonic eddies counterclockwise. Schools of anchovies, halibut, and sea bass came and went: silver flashes, small storms that well up from the inside of the sea but are short-lived, like lightning.

Perhaps despair is the only human sin.
