The following image provides an outline of the total 3,500 acre extent of the Highland plantation at its largest size in 1825. This outline is a rough approximation, and is not accurate in detail. From the original 1,000 acre tract, Monroe expanded Highland to the east up to Buck Island Creek, and to the west over the top of Carters Mountain. This outline is depicted below using an excerpt from an 1826 historical map from the Virginia State Library's collections.
