Geology Question


Recommended Posts

Just about every detectorist and drywashing prospector I have hunted with has made the comment "There used to be an ancient river running through here!" no matter where we were at the time. My question is: How can you tell if there truly was an ancient river flowing over the top of where you are hunting, or plan to hunt? Are there tell-tale signs that one can look for?

Finding areas with rounded stones, like big giant ones all the way down to pebbles can be an indicator. The natural terrain can also be an indicator, but I always look for the river worn rocks up on benches or almost anywhere for that matter. Smoothed off/ water worn bedrock can also be an indicator. You can literally follow these ancient channels (if still exposed at the surface) just by reading the rocks...

Take the time to research your area. contact local BLM offices and geology people. Also might want to get in touch with any local groups like GPAA, LDMA, etc.

Good Luck!

Thank you, Steve. I am currently a member of 5 different organizations, excluding LDMA (just way too much money for what you get). I am familiar with quite a few placer and other gold producing areas, just needed the clarification on the ancient river thing. Happy hunting.
