[Terrapreta] Old native earth ovens.

[John G. Flottvik]

Dear list.

Not sure this is relevant to our discussions but caught last part of a BC documentary called The Leading Edge.
In 2005 they have found several large First Nations earth ovens near Cash Creek BC. Ovens were big holes in the ground and lined sides and bottom with stones and used to steam/cook roots and edible plants. They would layer the plants and roots then cover with wet leafs then finally dirt. University of BC is on site excavating sites and interestingly, a lot of charcoal is found. These sites are apparently up to 3000 years old.

Regards

John
