Calkins Nature Area will host Hardin County Archaeology Day next month.

The event – the first of its kind at Calkins – will be Saturday, Feb. 22, from 10 a.m. to 2 p.m. at the Nature Area, which is located at 18335 135th St. in Iowa Falls. There are a number of activities planned. They include:

  • Flint Knapping Classes and Demonstrations: Head to the Calkins classroom at 10 a.m. to learn how arrowheads, spearheads, knives and other stone tools were made thousands of years ago. Matt Graesch of the Iowa DNR will be on site to demonstrate flint knapping techniques. Tools and other materials will be provided to the first 15 people who arrive for the demo, which will last from 10 to 11 a.m.
  • Guided Tours of Ulch Collection: Calkins Nature Area expanded its facility four years ago with the addition of the Ulch Collection. Jeff Ulch, of Clemons, Iowa, donated more than 10,000 artifacts. The items have been identified, cataloged, and are on display for the public to view. Ulch will be in the museum to guide the public through the collection.
  • Bring Your Artifacts: Amateur and professional archaeologists will be on site to help ID the public’s finds. This is intended for people who have found interesting pieces in fields, creeks, or on riverbanks that they need help identifying. Collectors are invited to bring a few items to share with fellow attendees. Please limit the number of things you bring.
  • Atlatl and Spear Throwing: Calkins will have homemade atlatls and spears for the public to try. Targets - will be set up in the prairie just east of the nature center.
