The town of Republic, Washington sits on a lake bed that preserved an entire Eocene forest in fine shale. Stonerose gives you a spot on the public dig, and the deal is honest and unusual: you may keep three specimens a day, and anything scientifically significant goes to the collection. People find leaves, flowers, insects and fish, and new species are still being described from what visitors split. Fee, seasonal.
Eocene leaves, insects, fish · Eocene, ~49 mya
