Tips for your fossil hunting adventure . . .

• Check the weather conditions prior to your visit. Heavy rainfall amounts may make the quarry area slippery & sticky due to the clay soils.
• Bring something to put your fossils in. Suggestions include: egg cartons, plastic milk jugs or ice cream buckets. Plastic bags tend to rip and may blow away. Tools are not needed as the fossils are lying on the ground.
• Although collecting is allowed, we ask that you take only for a personal collection. Reselling is prohibited.
