My wife and I were out exploring the side roads near our new home and discovered this quaint pioneer gravesite named Clarke's Cemetery. There is no sign to indicate the name of the cemetery, so we looked it up online. We wonder who the people were that lived and died here many moons ago. Enjoy the peace.
This puzzle final has been recreated from a traditional that we had here previous to the creation of our Compass Rose GeoArt. The Compass Rose Geoart we created during the Christmas holiday of 2018/2019 when my wife was too sick to go out geocaching. Instead, we stayed indoors for much of that Christmas, researched all kinds of things to do with navigation, and created this puzzle series for others to enjoy.
