This 1897 panoramic map of Carnegie is facing to the Southeast. Heidelberg is near the upper right corner. If you look carefully, you can see the trolley tracks in main street going from near the upper left to the lower right. You can get a bigger, clearer view of this map at the Library of Congress website. It can also be downloaded in a special compressed format which requires a special viewer. Instructions on obtaining the viewer are available at the LC website.
