Keokuk Geodes

Geodes from Iowa have long been objects of curiosity, their sparkling interiors containing some of the most beautiful crystals to be found anywhere in the Midwest. Although geodes are known from many localities around the world, one of the most productive and famous collecting regions is encompassed within a 35-mile radius of Keokuk, Iowa. Rock collectors commonly refer to geodes from this region as “Keokuk geodes”. In keeping with the world-renowned status of the Iowa geodes, the Iowa General Assembly declared the geode as the official “State Rock” in 1967.

The large number of mineral inclusions and the exquisite crystal groups that they form have made the Keokuk Geodes the most beautiful and the most sought after of all geodes by museums and collectors the world over. The most common size of Keokuk Geodes is about 3-4 inches across and sometimes reach 2 feet across and larger.

The Bevard Collection of Keokuk Geodes found in the tri-state area are on display at the Keokuk Area Convention & Tourism Office, 428 Main Street, Keokuk.

The Annual Geode Fest is the last full weekend of September at Chaney Creek Boat Access in Hamilton, Illinois, across the Keokuk-Hamilton bridge from Keokuk.    The Keokuk Area Convention & Tourism Bureau will host the 2018 event, September 28 - 30, 2018.
