With all the new faces here, I figured I'd also say hi and reintroduce myself. I am a professor of physics, astronomy and earth science, among other things, but most of what you'll get from me are photos of our immensely beautiful planet. Sharing that beauty is my passion; we're so lucky to be here.
Thank you. ๐ช

Fjallsjรถkull (Iceland) towers more than 6,000 ft above the surrounding landscape and is one of the dozens of glaciers that make up Vatnajรถkull, Europe's second largest ice cap. Seven volcanoes reside beneath the ice, leading to occasional subglacial eruptions and jรถkulhlaups.

Idaho's Upper Mesa Falls.
While the 10-story-tall waterfall is beautiful, it is the surrounding rock that I'm drawn to. Those cliffs are made of tuff, which is basically ash that fused together into rock. Here, it comes from the Yellowstone supervolcano eruption 1.3 million years ago! #Photography

Haha, well I do still crawl into just about every hole I come across whether or not I know what's in it. You never know what you might be missing! ๐

I knew of this beforehand, though I didn't know what it looked like from the outside.

Here's a look at my climb down into this cave after a few miles of hiking across mostly barren land. I made friends with the 4 crows that lived inside, they had such lovely little personalities!

Every now and then, I come across a place in nature that simply doesn't feel real. Crawling down a small hole in the absolute middle of nowhere and stepping into this scene was like being transported to another world. I found myself enchanted and struggled to leave for quite some time. #Photography
![A photo of the inside of a cave that has an opening at the top through which a perfect beam of light enters the room, filling it with a golden light and highlighting the dust suspended in the air. Directly below the opening in the ceiling is a pule of rocks from the collapse, with a circle of vibrant green ferns growing atop them. On the far right is a smaller hole that I climbed down through to enter the cave. [note: I will not publicly disclose this location due to the sensitive ecosystem within]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:acm2yz57z6weqbdbw5lpluu3/bafkreifrvpmyeo323nekvzthxshjlljhkuugqfc4jsocls7tpbzoa76z2i@jpeg)
