A multinational software corporation sends a car with a camera mounted on the roof down a one-lane unpaved forest road deep in the Salmon-Huckleberry Wilderness beneath Mount Hood. The camera snaps a 360º view of the wilderness every 50 feet. It captures the forest at dusk, or maybe dawn. Dark firs and aspen blur past and a log-strewn river throws froth. The photographs cannot be said to aid navigation of the forest road. What, then, is the purpose? This book represents a continuous 500 foot stretch of the wilderness.
