Notbohm Mill Archaeological District, designated 13LN296 in the state archaeological inventory, is a nationally recognized historic district located west of Alburnett, Iowa, United States. It includes the remnants of the mill's foundation, the mill race, and the now-dry mill pond along the east branch of Otter Creek.[3] This was both a grist mill and a sawmill operation. The mill began operating in the late 1860s. Frederick Notbohm began building the mill facility, which is the subject of this district, in 1875 near the now-defunct town of Lafayette. It continued to operate into the late 1930s and the mill itself continued to stand into the 1970s when it collapsed.[4] The historic district was listed on the National Register of Historic Places in 2000.[1]
