Wow, haven't seen anyone talk about "Aserdaten" in years. Aserdaten appeared on a 1948 Topo map produced by the Geo.survey. The one feature that made it a usable tract is it's elevation. It was approx 3 ft. higher than the surrounding swamp.
I'm as sure as I can be that I have been on the site. My guide was one Chester Mathis, aka "Uncle Chet". Chet was the typesetter for the Tuckerton Beacon for 50 years, and had an uncanny knowledge of obscure S. Jersey history. [Chet was extremely proud of never having spent a single night out of NJ] When he took me to the site we had to trek through from the Batsto side of the swamp. [This was in the early 60's, before the "Restoration" of Batsto. Confirmation of the location came from the "postmaster" at the Batsto store, Rod Koster.]
