A plant may be used as an indicator, provided it is established that its growth is controlled by certain factors which are related to the chemistry of the ore deposit.

It will also cover impact of environment and geology on the human civilization. It was suggested that in the absence of certain metals, the anthocyanins for red oxonium salts which become blue when they are complexed with excessive amounts of iron, aluminium, or other elements.

It is therefore possible that excessive amounts of some of these metals could produce a blue tint in flowers that are normally red or pink, and this could be useful field guide in prospecting.

Here the complexities of the Copper Trade intrude on an already controversial hypothesis, yet there can be little doubt about the antiquity of the subject, or its extension into the Pacific Northwest. When in the mountains there is the ginger plant, then below copper and tin will be found.
