Erratic Rocks & Cream City Bricks: Building Milwaukee From the Ground Down

The geological history of a city, starting at the surface with modern buildings constructed from local materials and going down six football field lengths to bedrock, and back six hundred million years in time, comes alive in this illustrated video. Geologist Norman Lasca also demonstrates the tools and methods by which a geologist gathers data and identifies the layers of deposits in an area, and how this information is used to produce 2- and 3-dimensional models of the geological make-up of the area.
