Geology and the Art of Stone Carving

The Lecture

Many members of the Northwest Stone Sculptors Association (NWSSA), including me, use Washington rocks in their art. In this talk, I’ll give an overview of this state’s geological setting  that provide these stones and describe the connections among basalt, dunite, jade, and the glacial erratics that we work with. I’ll highlight a few of my favorite sculptors, talk about some of the stone they work, and touch on tools and techniques we use to sculpt these locally sourced stones.

In 2009 King County geologist Greg Wessel curated a geology and art show on Vashon Island called, “Geo sapiens”.  At the show’s opening I met Shannon and Wilson geologist Bill Laprade. Bill was showing a couple pieces of Texas limestone carved with geology themes. His stone sculpture really made an impact on me. Bill encouraged me to attend a stone-carving symposium put on by NWSSA (see below). I attended my first weeklong symposium in July of 2011 and I’ve been making dust ever since.
