I hadnt ever heard of it (I live in Ca) so I looked it up, wow thats desolate. It sounds like the least California like area of California. It is far inland so it gets much colder much earlier than the grow counties you mentioned. According to wikipedia the county seat and largest city, Alturas (population 2827),the average low in august is 42 and 36 for september..so it doesnt look like its suitable for growing.
