Pete Ryder

PETE RYDER got the walling bug in 2015 at a workshop at The Stone Trust. After 32 years in aerospace engineering, working with stone was a big change and tremendously gratifying. Dry Stone Walling has been a growing obsession ever since. In 2016 he founded Touched By Stone LLC to build dry stone walls and features in southern New Hampshire. Pete is a DSWA Level 2 certified waller, and serves on The Stone Trust Board of Directors.

Whenever your building a wall, sooner or later it must come to an end. A cheek end is the typical way to end a wall. It is also called a wall end, wall head, or square end.
