During the early gold rushes of the 1800s, it was common practice for miners to flock to an area and quickly start prospecting for the easy-to-get placer gold in rivers and creeks.

In March 1856 seven men proceeding with a mule train over Trinity Mountain en-route from Yreka to Shasta were held up by a gang of five masked bandits and robbed of 25,000 in gold. The gang buried the gold in several places on the mountainside, and then fled.
They were rounded up a few days later. The notorious Rattlesnake Dick Barter, the Pirate of the Placers, engineered the crime, though Barter, nabbed while stealing mules to be used to carry off the loot, was unable to take part. About 15,000 of the gold was recovered in a ravine 12 miles from Mountain House, on the headwaters of Clear Creek. The melting of the snow and the coming of spring changed the look of the terrain. Attempts to find the rest of the loot failed, and 10,000 now several times in value by today8217s gold price still lies somewhere on the mountain.
The final heist occurred when Rattlesnake Dick hooked up with the Skinner boys. He decided to avoid his old haunts of the Mother Lode and concentrated on the rich spoils of the northern diggings. The robbery was flawless, but the Wells Fargo organized posse was hot on their tails. The gang split up. George Skinner was suppose to meet Rattlesnake Dick and the rest of the bandits at Folsom, however, the gold was too heavy to bring down the mountain pass and George decided to bury half of the loot in the mountains.
No one has been able to find the remaining 40,000 worth of gold bullion buried on Trinity Mountain even Rattlesnake Dick couldnt find where George had buried the treasure.
3. On May 1892 one of the most famous gold heists made the new town of Redding famous throughout the state. The Ruggles Brothers held up the stage to Weaverville, just west of Redding, in what is known today as Middle Creek road, and made off with the strong box loaded with gold. As soon as the stage headed around the turn the younger brother Charles jumped out of the Manzanita chaparral with his shotgun aimed, ordering a halt. The driver complied, but unbeknownst to the Ruggles, the stage had an armed escort, Buck Montgomery of the Hayfork Montgomery clan.
In an effort to save himself and his brother, John told the authorities that the stage guard, Montgomery, was in cahoots with them. He also revealed where he had hidden the gold, telling authorities that he had hidden it in Middle Creek. Attached to the strong box was a floating device that came within a foot of the top of the water that would help him in finding the stash later.
