During the summer of 2006, the HTS conducted archaeological fieldwork in the Johnstone Strait and Comox areas. Prior to the fieldwork, fish traps had been documented throughout the Johnstone Strait and Comox areas but the HTS believed that there were others that had been overlooked by archaeologists. The HTS also believed that there were hundreds of clam gardens that were yet to be documented. Thus the focus of the fieldwork was the identification of fish traps and clam gardens.
During June and July 2006, when the tides were low, HTS crews and Cullon, Simonsen and geomorphologist John Harper surveyed beaches throughout Johnstone Strait. Dozens of fish trap complexes were identified and more than 100 new clam gardens were identified. The crews recorded the GPS locations of the traps and clam gardens, took photographs and, for the fish traps, collected numerous samples of fish trap stakes for study and radiocarbon dating.
Interesting. Never heard of these things m'self.
I mean, I've sen small-scale fish traps, but not clam gardens nor ones of this (apparent) size.
