Shoofly Sand Pit (Fossils)

Join an experienced guide for a brand new geologic field trip to the Shoofly Sand Pit located about 70 miles from Boise. The sand pit contains abundant small fossils from Lake Idaho deposits, petrified wood and odd sandstone sculptures that you collect off the surface just by walking around. The sand pit is a public site located 4 miles west of the Shoofly Oolites and you could visit the Oolites after the trip if you wanted to go on your own. The Museum also has an archeologist shaker table that people can use as a group to sift sand for fossils (kids love doing this).

We will meet at the Albertsons Parking Lot on Hwy 21 andFederal Wayat 9:45 AM (near McDonalds but not at McDonalds). Your guide will arrange carpools at this location; the roads are paved except for the last 1.7 miles which is a good quality dirt road suitable for most (but not all) vehicles. We will return to the carpool location at ~3 PM. This is a new trip so even if you have done the Shoofly Oolite trip before, this new trip offers a different opportunity to find fossils and petrified wood and visit a new geologic site.

No dogs please. Bring lunch and beverages and dress for the weather. We will never be more than 500 feet away from the vehicles.

This trip and all of our 5-6 different field trips are FREE for museum members and children so please join or renew your membership for 2026. www.idahomuseum.org/membership
