Introducing Grass Valley
Historic Mill and W Main Sts mark the town center. E Main St leads north to modern shopping centers and mini-malls and into Nevada City. On Thursday nights in late-June through August, Mill St closes to traffic to serve up farmstead food, arts and crafts and music. In the town's outskirts are some of the state's oldest shaft mines. Being the first to exploit lode-mining (tunneling to find veins of gold in hard rock) rather than placer techniques (sifting debris carried by waterways), these were among the most profitable claims.
