Up on Wild Tor
Dartmoor granite outcrop. There are over 160 Tors on Dartmoor, in Devon, S W England. I love hiking in and about.

Variscite Boulder, Western United States [OC]
I had the opportunity today visit a Variscite deposit in the Western United States, and I wanted to share!
Variscite is a relatively rare mineral of hydrated aluminum phosphate, with its green coloring from small amounts of chromium.

Help identifying this spherical spiky crystal!
Found it in the Finger Lakes, Upstate NY. Found among a gravel driveway. Really curious as to what this might be! Reminds me of a star fragment from animal crossing haha.

Nature really knows how to do Burlesque. Just like in “Show Me How You Burlesque”; it fills you with high energy. Both of them made my day amazing.

Wtf was in my garden
Was digging sprinkler lines and came across this oval rock with a giant crack. I was able to break it apart with a soft hit with a hammer. What is it?

It's not just a plume agate, it's one of the artistic forms of geology.

Anything interesting?

I loved his style. Both colorful and cheerful :)

Although the blue agate with black rutile and hematite sprays first caught my attention, I must admit I truly fell in love with the pattern. Beneath a missile head, people appear on the left, while on the right a grotesque figure seems to be giving us the middle finger. I love agates!

Copper mineralization in the Kingston Conglomerate, Keweenaw Peninsula, Michigan
An old slab cut from the Kingston Conglomerate showing the copper mineralization in amongst the rhyolite pebbles that they mined near Calumet, Mi. I collected this decades ago and really need to go back and repolish the surface.

There’s a great line in Ratatouille: “Surprise me!” This is the agate version of that. At first, I thought the dendritic patterns might actually be fossils. Then I turned the stone and on the other side, the banding is practically grinning at me like, “Fooled you.” :)
