This leads along the edge of the woods to a knoll behind a green house, the fourth house passed, as shown on the topo. The two areas north of the higher are definitely lower. I hiked the stubble field west toward an abandoned building, with the highest ground about 200 yards past the building. The driveway ends at 1.1 miles at a home, with pasture and water tank adjacent. The owners were working the pasture and granted permission to park at the rear of the house and walk the field to the west.
High ground is in the field, with marshes visible to the north and west as per the map.
For the area nearer the highway, backtrack and park along the access driveway, within view of DE 44, and walk the stubble field SSE to obvious high ground almost directly behind the house on the highway. For the two areas north of DE 44, backtrack a short distance on 44 from Crystal Road to an unsigned paved road, shown on topo, that roughly parallels 44 to the north. Highest ground seemed to be near the north-south tree line just NW of the structure shown on the map. Follow the ridge line north across cornfields to the next high point, at or near an east-west tree line. I followed the fields further north, but found no higher ground.
