There are a large number and wide variety of historical maps available online. The maps below were collected from various sources and are but a small collection of what is available
The map below is from a survey of the Shenandoah River in 1832 by James Herron. The first two images make up the full map. They are pieced together from over 80 smaller parts each. The third is small section showing the bend in the river where Fort Egypt is located. The house marked as “A Weaver” is at the approximate location of Fort Egypt and probably is Fort Egypt.

This map below from 1862 was found at the Library of Congress web site. The entire map shows the Shenandoah River Valley from Winchester to Staunton. It is very large and it is recommended it be downloaded and viewed off-line versus opening it in the web browser. The other two images show the area around Fort Egypt at two different zoom levels. The house marked “Shank” is Fort Egypt. The owners name at that time was actually spelled “Shenk”.

The map below is from Massanutten by Harry Strickler. Fort Egypt is marked as #19 in “Strickler Acres”. The map is Mr. Strickler’s attempt to plot the Northern Neck land grants and early deeds in the Massanutten area. Harry Strickler’s map, while very good, takes some undue liberties with the surveys.

The map below of the Shenandoah River Valley is from the 1860’s and was obtained from the Library of Congress website. The house marked “Stover” across from Mill Creek is probably Fort Egypt.
