The Rock, Fossil and Dinosaur Shop

Bonanza Boxes

These boxes are 8’X 8’ and full of special sand salted with minerals, gemstones, fossils, and shells. There are over 200 specimens that can be found in any one of our three bonanza boxes. 

Families, birthdays, schools, or scouts can choose to dig into the big box. The big box or "party box" as we call it, is a 12' X 12' sandbox loaded with over 70 pieces. Roll up your sleeves, take your shoes off, and jump in to find your treasures to your heart's content. 

The price of the bonanza boxes is just $15 per group for the 8' X 8' box or $3 per person (minimum 8 people) for the party box.

These are great group activities that focus on teamwork, sharing, and exploring. The parties and school groups love these boxes as they can dig for as long as they want.


The Party loved the box. 

Here, 8 kids belonging to a birthday party spent over 30 minutes in the party box. 

Come check them out today!
