Rock-walled archaeological features are notoriously hard to date, largely because of the absence of organic material for radiocarbon dating. This study demonstrates the efficacy of dating clam garden walls using optical dating, and uses optical ages to determine how sedimentation rates in the intertidal zone are affected by their construction. Clam gardens are rock-walled, intertidal terraces that were constructed and maintained by coastal First Nation peoples to increase bivalve habitat and...
