1974 Aerial Imagery of Industrial & Dump Sites on Wausau’s Southwest Side

Among sites of interest that can be viewed in the aerial photos are Connor Forest Industries, Crestline (later SNE and WAULECO), 3M Company (aka Minnesota Mining & Manufacturing), and 3M Company’s massive waste dump at the time – now better known as 3M Park.

Imagery was flown April 26, 1974 and May 4, 1974 by Aero-Metric Engineering Inc of Sheboygan, WI, and is compared to contemporary images of the same areas.

Publicly available imagery from 1974 that can be accessed in the ArcGIS REST Services directory at the following link shows various industrial sites of interest on Wausau’s southwest side in great detail:


According to the Wausau Daily Herald, the vast property used by 3M for dumping “thousands of yards of material” from its operations had been offered to the City of Wausau in 1965. Part of the site had resided in the Town of Rib Mountain. 3M offered the property to the City with the stipulation that the company would be allowed to continue dumping its waste there until 1970.
