I have found no clear definition of what exactly was thought of as the Columbia Heights area, but for the sake of argument, I am guessing that it pretty much included everything on the relatively flat land between Ehrmanor and the Larch Mountain Road. This section will cover the west end of that area, to Chanticleer Point.
That being said, the anecdote below is placed by Mershon in his book between the Hanneman Farm, located across the highway from The Summit, and the Larch Mountain Road, which I include in a later section of the website.
However, lacking a specific location, I am sharing Mershon's story here.
