I assume you are talking about this area? Just drove past there a couple hours ago.
Have often wondered about that diagonal road between Cape May Ave and First Ave - it is shown on all the historical USGS topo maps.
This is from my "1899 in the Pines" map

And this is my "1949 in the Pines" map.

And finally, "1999 in the Pines"

I have not explored that area on foot, but there is only very faint evidence of this road on the 2012 NJGIN aerials

I included it on my "Map of the Pines HD" anyway, for historical purposes. The dark green shading indicates public openspace (Peaslee WMA in this case), so AFAIK it is private property. Parcels are shown on this map, they are rather faint dotted lines.

This is what it looks like in "LIDAR in the PINES HD", there are some bumps that might suggest something (real or imaginary).
Unfortunately, this region is only covered by the older 3-meter LIDAR. Hopefully some of the very high resolution 1-meter LIDAR will be available in the future, it should reveal much more.

If you don't already have them, all of the maps above are available for free at

BTW, when you talk about the "Hartman Survey Maps", do you mean the maps at this link, or are there higher resolution scans available somewhere else?

I started a project to geo-reference (rectify) those maps awhile ago, but never followed through. Was just thinking I should finish that project, in fact. Guy and Al said it couldn't be done, but I disagree - I think it can be "pushed and pulled around" until the roads and other landmarks match an accurate map. It's not all that hard, just time-consuming. Now the fact that the roads match doesn't mean that other objects on the map will be accurate of course, but it's a start.
There's an old thread on this topic somewhere. Here's an example of my work in progress showing that area overlaid on a USGS 24k topo - it obviously needs more work.
If there are higher resolution scans of the Hartman maps available, I'd like to know.
