This area has a rich and varied cultural history. When silver and gold were discovered in the area, a railroad line was put in along the Stillaguamish River. The boom town of Monte Cristo flourished. The economy changed and the rail line kept getting washed out by the river. Monte Cristo became a ghost town and is now a destination of hikers in the region. In the past, this area was also known for its logging industry. Remnants of equipment from decades ago can still be found in the forests. Visit the Granite Falls Historical Museum on Sundays to see some great collections.
