My daughter and I also visited the David Douglas exhibit at the Northwest Museum of Arts & Culture, or the MAC. This installation especially caught my interest because of the many indigenous plants collected by Douglas during his visit to the Columbia Plateau.
Douglas observed the process of baking black moss in the ground. He referred to the final product as "moss bread." It was interesting to see his perspective on an ancient indigenous practice that survives into modern times.
Bitterroot, camas, and black moss.
I was surprised to learn that California condors once flew the skies above the Columbia Plateau. This specimen had a wing span exceeding nine feet.
