2021 Map of Thomson

About this map

Thomson and the surrounding river bottomlands define this portion of the Upper Mississippi River valley at the boundary of Carroll and Whiteside counties. The village sits east of Potter Slough and Old Goose Lake, where the Great River Bike Trl follows the old rail corridor near Ebner. The topography transitions from the wet lowlands of the river plain to the rising bluffs and agricultural uplands to the east, drained by the meandering Johnson Creek and Otter Cr.
