An art form I enjoy, which has seen growing popularity these past few decades, is chainsaw carvings. As the name implies, the artist uses chainsaws of different size to work a piece of dried raw wood into the final carved piece. The carvings are often large and heavy. The wood is then generally stained or painted and sealed with varnish or polyurethane to protect the art.
While driving around Lake Tahoe this past summer -- a beautiful scenic drive that's highly recommended -- we came across several homes on the California side of the lake that had some fine examples of carved bears. I thought they were quite good and stopped to get some photos. Not sure if all the ones on the roof are wooded pieces, but they look great!
A uniquely American art-form, I think. I've a set of carved bear cubs in my own yard, but that's a story for a different day.
