What Twelve Thousand Years Looks Like In A Gravel Pit

The land around Buhl, Idaho, today is agricultural — irrigated fields growing potatoes, sugar beets, and grain crops, watered by the Snake River that flows nearby through its basalt canyon.

The gravel quarries are still operating in some locations along the Snake River Plain.

The Bonneville flood bars — the colossal gravel deposits left by the catastrophic outflow of Lake Bonneville fourteen thousand years ago — are the primary source of commercial gravel in the region.

The landscape does not look ancient.
