I think my favorite thing to do is to take pictures. I don't care where I go on vacation, or what I do, as long as I have my camera in hand and can snap pictures.
I love the Gorge Power House in Newhalem because there are some beautiful waterfalls there as well as lush plants to photograph. I really enjoyed the other day scoping out some good pictures.
The old rock steps were so beautiful. I loved how the plants were growing all over them. So whimsy and like a day of yesteryear.
This is the power house in the background (yes, I was trying to focus on the flower in foreground not just a taking a sloppy picture!) The water is tunneled I think 2 1/2 miles from the dam to the powerhouse. (Sorry I tried to find accurate information online & can't!). But I did learn that when Diablo Dam was built (5 miles upstream) it was the tallest dam in the world at the time at 389 feet. Unfortunately, you can no longer get public access to it. I didn't even think about that, since in high school we'd been across the dam several times, but that was prior to 9/11. Amazing (& kinda unfortunate) how much our world has changed.
