LONE PINE — Bernadette Grace's trailer, tidy and small, is well hidden behind a larger trailer charred and strewn with trash. It's far enough from the communal restroom and shower without doors, where addicts have cooked meth and drunks linger after dark. But close enough to the icy waters that sustain her.

This is home: a scrap of rock and dried grass that juts out into the waves of the Columbia River, with a wide view of the massive The Dalles Dam. The river is a constant reminder of Grace's fishing-centered childhood and Native American heritage; the dam is the root cause of all that her people lost when the backwaters swallowed houses, fishing platforms, and burial grounds.
