This is a modern wall, built a few years ago. The wood fencing was added after the wall was completed and a small number of farms (maybe 5%) incorporate the wood fence style. Most of the rock faces are 12" or smaller.

This picture shows a curve in the wall at the corner of the property.

An end shot. The wall is approximately 30" H (excluding the capstone) and about 30" at the base and is of typical size for this area.
