Malakoff Diggins

Our destination today was Malakoff Diggins State Park. Yesterday we learned about underground hardrock mining, today we learned about hydraulic mining. 


We started out by driving to Bridgeport Covered Bridge for some morning shots of the bridge.

After snappig a few more shots of the bridge we continued our journey to Malakoff Diggins. Using high pressure water the miners eroded the hills and let the tailings run through a sluice to recover the gold. The tailings then continued downstream to cause huge problems for the farmers in the valley. Hiller Tunnel is a 7,847 foot long tunnel they built to drain water and tailings from the mining area.

The tailings flowed into the Yuba River but there is no evidence of it at this point in the rive today.

On the way back we stopped in at Nevada City where we did a little wine tasting. The wines at Nevada City Winery were quite good but Indian Springs Winery not so much.

We dropped things of at the Winnebago and went to visit the Nevada County Historical Mining Museum. This is a great little museum with a lot of mining equipment and artifacts including a 30 foot diameter Pelton Water Wheel. The wheel was powered by a water stream from a 22 inch pipeline that developed about 350 psi of pressure. It was used to provide compressed air for the mining operations.

Then it was back to the Winnebago at the Nevada County Fair Grounds to do chores and relax.
