If John Muir had spent as much time here as in Yosemite, Lake Tahoe might be a national park today. You would not live here and neither would I. None of us would. There might be no ring of state highways surrounding the Lake. There might be no lakefront homes or piers. The 1960 Winter Olympics probably would not have occurred here, and neither would the development that followed. Lake clarity might still be 100 feet or more.
