The Forest of Pillars in Egypt’s Sinai Desert. Many believe the tubes were formed by lava, however it seems more likely to be ancient hydrothermal vents.
Dr. Bonnie Sampsell states:
“The rocks are composed of hematite (a form of iron oxide). The iron oxide was dissolved out of the sandstone bedrock, to which it imparts a reddish colour, by hot water emerging from deep in the earth. As the water reached the surface and cooled, the iron oxide precipitated in a ring around each source, forming a tube.”
Some pure titanium, and the TiO2 (“titanium rust”) is such a nice color. Also if you kinda squint it looks like a T-Rex is formed by the blue.
A large matrix specimen with a good covering of large, freestanding Cuprosklodowskite crystals.

A trippy chunk of malachite. Just look at those whorls!
Minerals are really awesome. This example of stibnite is both awesome and beautiful!
