I read a book about 25 years ago called TRASK. (don't recall the author.)It was set on the coast of Oregon---near Tillamook Head. If I'm remembering right, "mowich" meant something like good medicine based on a combination of things---hunting skills, having the proper medicine bundle, having mastered the tribes wisdom and lore etc. These combine to make a sort of gestalt where the sum of the parts is greater than the whole. Sort of like karma and good preparation make for powerful warriors. Mowich, therefore, had to be searched for and found---hunted and won.

Kla-how-ya was a greeting.
