July 2003
Skarn consists of coarse-grained calcium, magnesium, iron, and aluminum silicates formed by hydrothermal solutions, which replace limestone or dolomite near the contact with an igneous intrusion.

Ditches almost always started in the high country and contoured the mountainsides, making a long drop, usually many miles away, to the goldfields. There are ditches in Trinity County that originate at seven and eight thousand feet in the Trinity Alps that carried water almost thirty miles.
