Sand Harbor sits on the Nevada side of Lake Tahoe, where the Sierra Nevada meets the water in a jumble of granite boulders and startlingly clear shallows. The emerald water, sandy coves and smooth rock formations have made this Nevada State Park one of the lake's most visited beaches.

What fewer visitors know is that Sand Harbor once served the timber trade. A steamship called the Niagara hauled log rafts up from the south end of the lake. From there, they were loaded onto rail cars and sent to a sawmill before riding the Incline up to log flumes bound for the mines of Virginia City. Today, the same shoreline hosts an annual Shakespeare festival in an open-air amphitheatre.

VoiceMap's self-guided audio tours use Sand Harbor to trace the lake's transformation, from industrial workhorse of the Nevada silver boom to the threatened ecological treasure it is today.
