With the worth of gold presently operating so excessive, variety of persons are changing into all for leisure prospecting. Sadly, one of many issues is discovering a spot the place they’ll get their arms moist and actually discover some actual gold. Right here's a chance that’s close to to thousands and thousands of California who properties the place anybody can go and pan their very own free gold. Not removed from sunny Los Angeles within the San Gabriel Vary, the San Gabriel River has yielded a major quantity of placer gold, together with some good sized nuggets. The San Gabriel Mountains are positioned in part of the Transverse Vary geologic province of Southern California, only a brief drive north of Los Angeles. This location has turn into a highly regarded spot for native prospectors – a lot of the placer space is designated for recreation and anybody is welcome to prospect right here without spending a dime.
It’s not uncommon to see numerous people out right here on weekends, though not all of them are prospects. A dozen people right here and typically a half a dozen there are unfold alongside the San Gabriel River engaged within the quest for gold. The principle placer space is positioned about 30 miles north of Azusa and deep within the Angeles nationwide Forest, from the Camp Williams trailer park upstream for a ways. The San Gabriel River isn’t terribly wealthy, nevertheless it does persistently yield some good small nuggets, flakes and colours of gold to the hard-working prospector.
Placer gold was found within the San Gabriel vary within the 1840s within the space has had a number of productive durations since that point. Nuggets and flakes of placer gold have been obtained from each the stream gravels in addition to older terrace bench gravels. Some good sized nuggets greater than an oz. in measurement have been produced from these deposits. The bench gravels have been diminished by hydraulic mining in addition to tunneling alongside the bedrock. Whereas numerous streams within the area west of Mt. San Antonio (often known as Mount Baldy) have been productive, the East Fork of the San Gabriel River has produced most placer gold.
In 1874, it was reported that greater than $ 2 million in gold had been produced from this space. Along with the productive placer deposits, there are additionally a number of onerous rock mines positioned close to right here. Lode gold mining was best through the interval from 1903 to 1908, nevertheless there was some exercise once more within the 1930s. The estimated complete output of the lode mines right here is about 50,000 ounces.
The gold quartz veins happen in schist and gneiss, each of that are metamorphic rocks. Whereas the values are spotty, the ore deposits are wealthy in locations. The veins are often lower than three toes thick and don’t prolong to any nice depth. The oxidized zones close to the floor yielded the richest ore. The erosion of the veins in these onerous rock deposits are the supply of the placer gold nuggets discovered within the gravels.
The East Fork of the San Gabriel River is a well-liked spot for each picnic goers and prospects from southern California, and nonetheless yields small quantities of gold. The East Fork was truly the second spot the place I used to be capable of finding some placer gold of my very own once I first began prospecting. Whereas the mattress of the river does include gold, the gravels are very deep and getting all the way down to bedrock is about not possible in most locations. I all the time did my greatest at this location once I was digging within the bench gravels above the trendy stream. I might dig the fabric from the financial institution, then haul it all the way down to the river the place I processed it in my sluice field. Small garnets are frequent within the concentrates from this location.
