Tynsky's Fossils
Generations of Tynskys have quarried Fossil Lake, and the family still runs a gallery in Kemmerer alongside a public dig. They hand you tools and rock, you split slabs for four hours, and you take home six to ten complete fish. The catch is the ten-person minimum booking, so gather a group before you plan a day around it.
The card catalog
| What you can find | fossil fish, knightia, fossil plants |
|---|---|
| Access | Fee dig — Fee, seasonal |
| Fees | $125 per person with a TEN PERSON MINIMUM to book - a family of four cannot reserve a dig on its own. That buys four hours of dig time and 6 to 10 complete fish to keep, rare species excluded. Children under 4 are free. Complimentary fossil cuts included; tools and rock supplied. |
| Season & hours | Usually open June through September and dependent on weather - the shortest season of the Kemmerer quarries, not the longest. Book through the form on their site or call 307-413-0820. |
| Kids | Family-friendly — Four hours is a long session for small children, and the ten-person minimum means this works for an organized group, a reunion, or a school outing rather than a walk-up family. Under-4s are free. |
