Last summer I picked up a collection of rainbow obsidian carvings with some intense colors. Some people were asking about them in prior tweets so today I've dropped them all on my etsy here:
Come along with me on my carnage (I mean course) check this morning. What should be one of the most beautiful golf courses in the country is being destroyed by herds of javelina. If anyone has a contact in AZ state govt that can help us find a solution please pass it along.

Them: why would you pay $79 for a box of used pencils lol
Me: because they’re original Eberhard-Faber Blackwing 602’s and I can resell them for $40 a piece
Came to a wild realisation. When mud larking or digging through 19th century tip, you'll find army of discarded single use tobacco clay pipes. Currently accumulating rubbish are, disposable plastic vapes.
Over a hundred years. And the people didn't change, just the delivery did.

Rare pencil type used by famous animators and composers in the 1950's-1970's. Has an interesting combination of ingredients that allows it to smoothly write twice as much for half the force
Ant Hill garnets from Arizona. These are pyrope garnets mined by ants and deposited on ant hills. They are then collected by the Navajo and sold to gem cutters.

I feel fossil prep is under appreciated by the general public. The amount of time and skill it takes to free a fossil from rock and make it presentable… fossils do not just pop out of the ground museum-ready
For reference, here’s the Jebel Issoumour near Alnif where locals dig trilobites following one specific layer for several kilometers. I was there doing research in 2005.
A "floating island" in Chippewa Lake in Wisconsin that locals often have to push into place when it blocks the bridge, the only passage between the eastern and western parts of the lake

Geology is hard on the ego, it’s like, in a few million years there will not be a trace of you or anything you’ve done or accomplished. You’re not even a blip in geologic deep time
For everyone being like “what?”, James BoBo Fay talks about it one some podcasts (ie: ep 566 of The Confessionals) about filming and how there was a huge thing in a Pennsylvania lake that moved fast but the producers had no interest because it wasn’t Bigfoot

Woah I didn’t realize Morton Salt mined salt 2000 ft under Lake Erie (didn’t realize there were salt layers thick enough to mine). Check out the quality of this halite!
1) it did not fall into a volcano, meteors are not visible at that altitude, it’s probably 30 miles away in the direction behind the volcano
2) credit the photographer you A-hole
3) pic by
This is a fun paper, they used synchrotron microtomography (essentially an X-ray powered by a synchrotron) to scan a piece of Triassic dino coprolite (poop) to 3D image all the beetles hanging out inside.
Philip Jacobs, the fossil collector and finder of giant pliosaur, was completely left out of the BBC documentary. This sort of thing happens a lot and discourages collectors from wanting to work with academics and others.
Occasionally the Windows log-in page shows me a geological site I've never heard of, for example, the Bungle Bungles of the Kimberley, Australia. Which gets its stripes from bands of cyanobacteria.
Pleochroism: a optical characteristic of some minerals where it features different colors depending on the viewing angle. This is a specimen of Cordierite or Iolite featuring this phenomena.

Some erasers were ok. All the current pencils calling themselves Blackwings are not the original nor could they get the mix just right. The original company went out of business a few decades ago and some startups took the name
Got a package from Canada with some damage and a “we apologize for its condition - Canada Post” bag.
I joked that it’s Maple Syrup.
I sniffed it. It’s Maple Syrup
Opal deposits in seems and cracks in rocks, so sometimes a proper whack with a rock hammer will reveal a bunch of thin gorgeous opal, as can be seen here in a specimen of Boulder Opal from Australia
Federal authorities are looking for two men who were caught on video damaging protected rock formations at Lake Mead National Recreation Area last weekend.
Who knows these asshats?

What are you looking at?
Slices of diamonds with natural trefoil patterns inside.
Extremely rare, likely caused by differences in nitrogen while the diamond crystal was growing.
Finally got my hands on some of these.
Alright, I've done it, I've created the Geological Advent Calendar: 24 boxes with specimens of minerals, fossils, gems, and more!
You know shipping is going to be crazy this holiday season so get it early. $160 with free US shipping:
Was opening a mixed bag of rocks I won at auction (there was a variscite I wanted) and noticed one of the rocks had a suspicious pastel color. Pulled out my Geiger counter and yup

I just sold a signed book by a physicist, who passed away a decade ago, to a buyer who turned out to be his daughter who’s always wanted a signed book from her father
Ah now this is a fake pallasite. They’ve been making a lot of these in China where they mix earth sourced olivine into melted metal and then cut slices of it. You can tell by the angular olivine, even distribution, and lack of etching in the metal.
It freaks me out that people can go hiking and wonder off the trail by a couple hundred feet and boom they’re gone! Lost in the woods! Not found for years or never

What if there was a way to:
• Mitigate climate change
• Create more life
• Grow the economy
• And make money along the way?
