Happy Birthday, ICMJ!
September 2020 by Scott Harn
You’ll note the text on the cover now says “Celebrating Our 90th Year.” Yes, we are in our 90th year of publication!
A lot has changed since our gold and black cardstock cover bearing the title California Mining Journal. Through the years, we’ve tried to balance our content to include all levels of experience, from first-time prospectors up to small operations. We’ve sought to provide consistent, quality articles in every issue, and we very much appreciate the feedback and compliments from you, our readers. It’s also been a challenge to adapt to the younger, Internet-based generation, but we now have over 20 years’ worth of articles online along with downloadable 3D issues for the past six years at www.icmj.com. We also have Facebook, Twitter and Instagram accounts. Yes, we are hip 90 year olds!
But we’ve noted that the majority of our readers still prefer to carry a print copy with them around the house or out at their mining site, though there is an increasing crowd of paperless online-only readers too.
To all our readers, we are grateful and we look forward to reaching 100 with your continued support.

Why Is The Gold On Bedrock—Or Why Is It Not?
Gold on the bedrock is a good rule of thumb, but not one that is 100 percent effective. There are plenty of exceptions. So, how does a prospector recognize those exceptions?
The "Rip-Roaring" Flood That Washed Out Mazuma, Nevada
Okay, now for the story of not only the Mazuma flash-flood, but also of early day happenings in the surrounding Seven Troughs area as related to me by Gloria’s (late) grandmother, Gommie. At this time (1953-1954) Gommie was in her late 60s and often reminisced regarding her early life in Iowa as a schoolteacher...
