I spent time yesterday in the map library of the Clark University Geography Department. Looking at an enormous and colorful map of the details regarding what kind of rock lies where in Vermont, I honed in on the site of the Middle Bridge.
I graduated from Clark in 1970, and in my freshman year took a geology course to satisfy the Science distribution requirement. I came away with a rudimentary knowledge of rocks, and a great admiration for geological maps, color coded for the specific type of igneous, sedimentary or metamorphic stone serving as bedrock for a particular location. Just as the swirl of a river inspires comparisons to abstract art, so do these beautiful maps.
