In underground placer work, the contact point of the bedrock tunnel and the gravel is a very weak point and always has to be timbered. The bedrock here is thin, fractured, and the gravels loose from many years of oxidizing.
Trinity County is located in the far northwest corner of California and stirs up many different memories for those who have been there.
