The Grundy County Museum is located in Morrison. It displays a wide variety of artifacts from Grundy County's cultural past and also includes natural history displays of wildlife mounts and aquariums. The aquarium room contains large and small aquariums totaling almost 1,500 gallons of water! An interactive underwater mural is a popular feature in the aquarium room, as well. Come check things out! The museum is open from 8 A.M. to 4:30 P.M. on Tuesday, Wednesday, and Thursday all year round. And other times by appointment. Other buildings from the past are also located on the museum grounds. They include Colfax No. 3 a one room school house, Peck Cabin the first log cabin constructed in Grundy County, a railroad interpretive, and Heritage Center & Agricultural Hall the newest museum attraction. We invite you to check out these and other facilities! Donations of artifacts or monetary contributions can be made by calling the Grundy County Conservation Board at 319-345-2688.
