During our last trip to Preston Falls, the air was clean and clear as we drove across the Central Valley. We noticed that we could see plenty of mountains stretching up and down the Sierra, particularly to the north. First the Crystal Range, west of Tahoe, and then we picked out the snowy summit of Mt. Lassen, further north. And then, as we hit the top of the bridge over the slough at Terminous, we looked hard, and saw the tiny but identifiable bump of snow even further north: Mt Shasta. According to Google, that's 250 miles away.
No, we didn't take pictures, because we were moving to fast, and our little camera was too small to truly capture the moment. But it was amazing.
