Stone Wall This photo shows a non-linear stone wall. The line of the wall is indicated in blue. The red circle indicates a large in ground boulder incorporated into the wall construction. The width of wall varies from single stone wide construction to a wider more mound shape construction (or deterioration). Land division between family members and property line disputes sometimes resulted remarkable erratic boundary walls. Evidence for such erratic boundaries can be found in property deeds and maps. Native American ritual stone walls used to define sacred space, provided features for spirits to travel along, link different components of the natural landscape together, or accentuate landscape features also tend to create unusual stone walls. This wall’s course was intentional laid out to include the large boulder. This linking characteristic is typical of Native American stone walls.
