Hetch Hetchy, Glacier Point, Tunnel View, Mirror Lake, and a myriad of ancient roads are side trips I took during this visit. Any one of the biggies I’ve written about already would be reason enough come to Yosemite but there’s so much more to see. Some of these are worth setting apart and mentioning.
The water supply for San Francisco comes largely from behind a dam built at one of Yosemite’s great canyons. After the 1906 San Francisco earthquake and fire, Hetch Hechy within Yosemite was the wildly controversial selection of location to create a huge reservoir. The city was growing rapidly; it needed a large and dependable supply of water. Not only was water important for daily life but also for fire control. Steps needed to be taken to preempt another out-of-control fire such as the one that destroyed the city.
