Longhorn Cavern

with 29 comments


I’ve lived in Austin since 1976 and the Lady Eve since 1988, yet not till three days ago did we finally visit Longhorn Cavern State Park, which is only about an hour’s drive west of home.



I’d called ahead to ask about the photography policy and was told pictures are fine as long as flash is turned off because it would disturb the bats that live in the cave. Figuring my regular camera wouldn’t have enough light without flash, I took only my iPhone 14 into the cavern with me.



Turns out the person I spoke with over the phone misinformed me. After we were inside the cavern, our tour guide made it clear that pictures with flash are generally fine, the only exception being in a spot where a bat is present. To tell the truth, I probably got better images with the iPhone 14 anyway. It’s good at taking pictures in low light, and it lets me go into raw mode to retain as much photographic information as possible (unlike the conversion to jpeg, which tosses out a lot of data). In addition, as long as I stick to the 1x camera, the pictures come out at a whopping 48.8 megapixels each. I stuck to the 1x camera.

All the lighting in these pictures came from the spotlights that the park service has installed here and there throughout the cavern. In many cases I went for abstractions of light and shadows.

Surprising Facts


“If you think of the United States as a football field, all the garbage that we will generate in the next 1000 years would fit inside a tiny fraction of the one inch line.” For the uninitiated, let me add that a football field is 3600 inches long, so an inch is less than one-thirtieth of one percent of a football field’s length—and the quotation says we’re dealing with a tiny fraction of that already tiny amount. Would you have expected that?

You can learn more surprising facts about recycling in a seven-minute video by John Stossel.
One is that “Even Greenpeace says most plastic cannot be recycled.”
