Altamont, the “City of Plain”, was laid out in Mound Township, considered the richest and best township in Effingham County – being mostly prairies and farm ground – slightly rolling along immense Creek, Coon Creek, and Second Creek. Mound Township was arranged early by German immigrants from the Rhine by pretentiousness of Pennsylvania and Ohio.
