I came across diatoms and radiolarians–tiny little sea creatures–while looking up the history of climate change over the span of geologic time that cats and cat-like creatures evolved.
I’d never heard of either one before but noticed that the images in various scientific papers were beautiful. What a surprise to learn that Victorians knew this, too, and actually made microscopic art of diatoms!
And someone is still doing it today.

Here is a video of a very famous lake. It’s exceptional because there are people in almost every shot, but you never lose sight of the scale.
Those cracks and bubbles are so spectacular because the water of Lake Baikal is very clear.
The geology behind Baikal–the oldest and deepest lake on the planet–is complicated, even for the experts. Some think it’s a result of the distant India/Asia continental collision. Others think that there might be a mantle plume far underground, forcing the continent to spread apart here.
Whatever is going on has built something awesome at this moment of geologic time. When spring comes, you need a satellite to see the ice melt on this lake!
This is the video you’ve always hoped some mountain climber would make:
He missed one of the biggest wonders in these mountains, though – coral reefs!
