Natural Building is a huge part of the VBC, and often involves "cob", which is a mixture of clay, sand, and straw. It can be formed into a multitude of whimsical shapes and when finished correctly and treated right, can last for years and years and years.
I snapped these pics of the sites on Tibbetts so other folks could see how fun cob work is. Go find the site nearest you and get muddy yourself!
The three sites featured here:
1. SE Tibbetts at 23rd Ave. Cob Bench.
2. SE Tibbetts at 22nd Ave. Cob Bench with roof.
3. SE 22nd between Tibbetts & Powell. Cob Bench in front, with walkway leading to steps (and up to door) behind it.
