Signal was established in 1877 to process ore and supply provisions to the areas numerous small gold & silver mines. In its heyday it boasted 800 people and 200 buildings but only the stone mill foundation and the old graveyard near the banks of the Big Sandy River remain today. South to the Gold Bug Mine via long shelf road and exit via Alamo Road to US 40. Long day but youll be rewarded with interesting geology, a large quartz float, great views & solitude.
