California Grass Valley Main Street Trolley Real Photo Postcard

Grass Valley, California, established during the California Gold Rush, evolved into a significant hard rock mining town by the late 19th and early 20th centuries. East Main Street, as depicted, was the city's primary commercial artery, lined with substantial brick and wooden buildings featuring covered walkways, a common architectural style for business districts in the American West designed to protect pedestrians from sun and rain. The durable construction reflects the town's sustained economic activity beyond the initial gold fever.
