The White River Bed, located in the Cascade foothills of Washington, is a lesser-known thunderegg site that yields nodules with subtle yet attractive agate interiors. Thundereggs from this area typically display soft grays, tans, and occasional hints of lavender or blue, with interiors that may include faint banding, moss, or druzy quartz pockets. The matrix is usually light gray rhyolite, often weathered and rounded from exposure. While not a high-volume site, White River material is valued by collectors for its natural elegance and the potential for clean, polished faces that reveal quiet but intricate internal features.
