Tuesday, May 30.
This is your sign to learn more about 馃 cool rocks 馃. Become a certified rockhound now.
I have something so important to tell you: Last week my sister and I smashed a bunch of rocks in half. It released something primal within us, and I am compelled to preach the one universal truth I now know;聽The key to life is to recognize you鈥檙e a certified Rockhound.聽A Granite Groupie. A real Basalt Head.聽
Some rocks are almost made for throwing. A life like yours demands more exploring. Go on, my little聽#rockhound. Find a rock to smash open. The best part about your new hobby? In the absolute worst-case scenario, the rock is simply filled with聽more rock. What a beautiful thing.

there are no rules to what's a trinket. you find something and it's pretty/meaningful to you then damn, that's a pretty good trinket.
however, trinkets must never be stolen. always make sure you are only in possession of ethically sourced trinkets.
here are some of my trinkets.

Cool rock time! :D These are from a parking lot on the way to the public library :3 It was also nice and rainy, so it was easy to see the patterns and colours better.
The wispy, veiny-looking one is my favourite, because it has a mark that looks like a little heart on it <3

I found a nice hunk of shiny rock in the woods (much more reflective and shiny in person than in any photo I took). The rock ID app says it's most likely schist.

The "crystals and minerals are cool but they do not have 'healing auras' or any of that nonsense" post that @a-dinosaur-a-day reblogged got me thinking about my own rock collection.
I've been collecting rocks almost my whole life, but during middle school I got REALLY into geology and rockhounding.
Tumblr media
Edit: here鈥檚 my rock collection

Spawnette and I were rock hounding in the mini quarry in our woods. We have found a few glacier deposited rocks. But we have been hoping to find a fossil in the shale.
They are done harvesting shale. If you look in the back you can see they are dumping fill. On the left rock face you will notice a pink spraypainted line. That how far they will fill up the hole. And then this will be a retention pond for storm water.
Today was probably the last day we could be here. Monday they will finish dumping fill.
We have had fun exploring in here and will miss the rock specimens. But I know of other areas within a half hour that we can hunt for precious stones.

I got a Geiger counter!
Let鈥檚 look through my collection for some Spicy Rocks!聽 I鈥檝e never deliberately collected radioactive specimens, so I have no idea what I鈥檓 going to find.
First, though, let鈥檚 test the baseline level of radiation in my house.
Tumblr media
It鈥檚 fun to hear the Geiger counter click as it detects radiation.聽 20 counts per minute.聽 Nice!聽 You鈥檙e unlikely to ever see a count of zero, as pretty much everything in the world, including the human body, gives off a little bit of radiation.聽
20 is a normal baseline, nothing to be concerned about.聽 Standing in my house, I鈥檓 getting a radiation dose of about 0.00013 milliseieverts per hour - or a little over one mSv a year.聽 This is an average yearly dosage of radiation for people in my country, and is something my body can easily process.聽 For context, a dosage of 100 mSv would slightly increase my risk of cancer, and a dosage of 1000 mSv would immediately give me radiation sickness.
But enough about these boring, safe amounts of radiation.聽 I want to see some spice!聽 Let鈥檚 check over by the Rock Wall!
Tumblr media
Hm, I鈥檇 expected the CPM to be noticeably higher around my rock collection, but I鈥檓 getting nothing!聽 Even testing each individual rock, nothing鈥檚 more than a few ticks above the baseline.聽 So far, my fancy new toy is looking like wasted money.聽 :c
Tumblr media
WAIT!聽 THERE!!聽 62 CPM!聽 That鈥檚 three times higher than the base reading in the rest of my house!!!聽 YESSS!!聽 THIS ROCK IS SPICY!!!!
Tumblr media Tumblr media Tumblr media
Here鈥檚 the rock that鈥檚 setting off my Geiger counter.聽 (Yes I鈥檓 touching the spicy rock with my bare hands, don鈥檛 worry about it.)聽
This fossil, which is as big as my head, is part of the femur bone of a Megalonyx, a North American giant ground sloth!
Tumblr media
These huge animals could grow as big as ten feet tall.聽 They lived alongside humans during the last ice age, and it鈥檚 theorized that humans may have hunted them to extinction.聽 This particular fossil was found in a phosphate mine!
Why is it radioactive?聽 Because... sometimes fossils are just radioactive!聽 They spend a lot of time in the ground, which is full of radioactive minerals, and often radiation just gets all up in there.聽 There are some fossils on display in museums which are so radioactive that they have to be coated with lead paint for the safety of curators and museum-goers!聽 Compared to those, this femur bone is barely radioactive at all.
So is it really safe for me to have this in my house, much less handle it with my bare hands?聽 Well, yeah!聽 Remember, despite having this spicy rock in my collection, the radiation baseline in my house is completely normal.聽 Here鈥檚 why.
Tumblr media
Even just a few centimeters away from this specimen, the Geiger counter鈥檚 reading is halved.聽 A few inches away, and it can鈥檛 detect any radiation at all.聽 It basically has to be directly touching the rock to get an abnormal reading.聽 Which means I also have to be touching the rock to receive a meaningful amount of radiation exposure.
But even holding this rock in my hands, I鈥檓 only getting a dosage of about 0.0004 mSv per hour.聽 If I never let go of this rock for an entire year, I would get a dose of about 3.5 mSv.聽 Which is... still completely within the safe threshold for my body to process.聽 Nothing to worry about!
Man, I gotta start collecting some spicier rocks.

Do you collect beautiful rocks? For garden decoration, maybe.
I do! I use them to decorate the pots on my balcony, so only small rocks for now. When I have my own land, then I will collect rocks all sizes. Most rocks that I like are found in the river, forest and digging in my garden!

It鈥檚 been a while since I鈥檝e been able to find some cool rocks outside, so I was glad to find these in some local parking lots :)
The first batch is from a grocery store parking lot, the big stripey, layered one it my favourite <3 The second batch is from a rainy day in a thrift store parking lot.聽
The very last little orangey-brown one is from a neighbour鈥檚 driveway. It鈥檚 really pretty and translucent, with slight variations of colour when held up to the light, it definitely reminds me of an agate (like the more common ones found in rivers and lakes).聽
