The Poker Flat District is in northern Sierra County about 10 miles north of Downieville. According to the State Mineralogist (1927), "Poker Flat Gold Gravel Mining Company spent $65,000 prospecting for a gravel channel under this lava. A vertical shaft was sunk 537 feet. From a point in this shaft 505 feet deep, an incline was sunk at an angle of 65° to a depth of 675 feet. After driving 88 feet horizontally, an inclined winze was sunk 46 feet, giving a total vertical depth of 717 feet below the surface. The first incline from vertical shaft, and the horizontal drive of 88 feet, passed into and through what appeared to be either a projecting knob of serpentine bedrock on the uneven lava and bedrock contact, or a large detached mass; beyond this, to the north, in which direction they were driving, the lava and bedrock contact was still sloping steeply down when work stopped in January, 1914."
