Re: Spanish Dip Needles - Miner's Compass
This is very interesting.....I spent one summer under one of those domes. I found the gold was like you said except that our clay was blue. I guess where you are located and when the ash was put down determines the color of the clay. A friend had a book on the Tertiary Gravels of Northern California that was written in 1912 and anytime I located something new to me I would read the book. What was amazing was the fact that the newer books all refered to this old book. ....ArtMrs Oro and I have a placer mine that is nearly all high-bank, tertiary channel that is capped with volcanic lava "dome" of very hard rock. The old-timers who worked this mine tunneled under the lava dome, hunting for pockets in the ancient riverbed and we did the same - some of the pockets, which lay atop a white clay "false bedrock" paid off very well.
