Just outside the limits of the growing town of Oelwein, Iowa, to the southeast, the Chicago Great Western Railroad company, in order to lessen a troublesome grade, have excavated a cut nearly a mile in length. At the end farthest from the town, where it passes diagonally through a ridge, it has a maximum thickness of thirty-two feet. This ridge has a northwest-southeast trend, and is one of the ordinary gentle swells characteristic of the drift of this region.
