The Happy Valley Bed, located in Wasco County, Oregon, is a thunderegg site known for producing nodules with vibrant agate interiors and bold natural patterns. Thundereggs from this bed often feature rich reds, oranges, and grays, sometimes with moss, sagenite, or plume inclusions that add striking complexity. The rhyolite matrix is typically dense and reddish-tan, and the eggs themselves are well-formed and solid, making them ideal for slicing and polishing. Happy Valley material is valued by collectors for its strong color contrast and lapidary quality, making it a standout among Wasco County’s lesser-known but high-potential beds.
