This is a Genus 3 Triple Link sculpture made from a 2"x8"x8" piece of Maple Ambrosia. This sculpture has three holes (genus 3) and the raised edges form three linked knots, each one passing through a pair of holes. Maple Ambrosia is a species of maple in which the ambrosia beetle has bored, making unique intrusions. This picture is a closeup of the most visible such mark.
