Ruin marble. I've seen this particularly atmospheric example in the Natural History Museum in London.

Link to source? I'm trying to figure out what the color codes mean...

Sorry it's a really old picture from my HDD. But a nautical chart will tell you what you want to know. Anyway, as a sailor in the bay I can guarantee that blue is deep, red is shallow, and green is in between.

The twitter post contained a link to a gallery with more amazing photos of volcanoes (including volcanic lightning) by the same photographer (Takehito Miyatake).

Warmly (or maybe hotly 🙂) recommended:

Here is one I found on Twitter:

I love volcanic lightning ... partly because of my love for all things storms
the process for generating eruption lightning is just the same as for a thunderstorm
namely charge separation between particles in either the ash cloud or raindrops/ice crystals, respectively.

The Taal Volcano in Luzon, Philippines. I have been out to the island in the centre of the crater a couple of times.
but, fortunately, not during an eruption like this .....

This fits with "cool geological images" IMO. This picture was taken about 4 years ago on a backpack trip in the SE part of Olympic National Park. It shows seabed layers upended by about 70 degrees. The current geology thinking holds that the Olympics were formed when an island arc, Siletzia, was too large to comfortably slide into the trench that defined the boundary between the ocean floor plate and the North American plate. There are many places in the Olympics with rock layers contorted as seen in this picture. In some places, the layers got upended past the vertical, and then partially bent back down, making a U shape.

The lake in this basin is named Lake of the Angels.
