Fossil huntingTips for an enjoyable visit to the Fossil & Prairie Park Preserve

  • Check the weather conditions prior to your visit. Heavy rainfall amounts may make the quarry area slippery and 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.
  • The Park is open from Sunrise to Sunset. The Center is open weekends in May, September & October from 1-4 p.m. and Memorial Day thru Labor Day from 1-4 p.m. Daily.
  • Although collecting is allowed, we ask that you take only for a personal collection. Reselling is prohibited.
