This photo is of a farm field on the east side of Rangeline Rd south of Rt. 2 and shows how perfectly flat this area in the glacial outwash plain is.

This photo taken just south of Rt 30, in comparison with the previous photo, shows that the terrain becomes much more hilly the further north you get.  This is because at this point you are no longer in the glacial outwash plain, but crossing over the Valparaiso Moraine.
