Prospecting & Detecting
The Essentials of Dry Washing
August 2013 by Chris Ralph
Most dry washers have a feed rate adjustment. It needs to be set so that the material flows evenly over the riffles and does not bury them.
What's In A Name?
The names attached to these areas came about from many sources. Many are easy to see why the name was given while others had a more contrasting note to them.
Attention to Detail - Part II
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.

This fine gold that is so common is probably the most notorious for eluding our riffles and mattings.
What Happened to The Gold Prospecting and Mining Summit?
We continue to seek out a patented mining property with an owner who is willing to host such an event with a water supply and enough remaining gold to make it worthwhile for the students.

Placers that are directly associated with lode deposits are sometimes overlooked and may have good potential for those who are willing to search for them.
Detecting Alluvial Bench Deposits -- Pt II
Walking around the gulch and exploring the upper drainage, picking up different rocks and inspecting them with a good loop, and looking them up in a field guide of rocks and minerals of your region will help you understand how the gold got there.
