OVERDOSE VICTIM - the corpse stares up at you, lifeless

KIM KITSURAGI - "Detective, we need to record the cause of death."

1. "Another casualty of communist ideology."

2. "Fentanyl? Let's put down Fentanyl."

3. [Inland Empire - Heroic] "Kim, did you know that paracetamol gives you autism?"

Visited a Paleolithic cave site in Switzerland recently that was only accessible via a giant (wobbly) ladder up a cliff face. They installed a tiny funicular to get the sediment down!
Photo taken in a pine forest. To the right hand side is a rough cliff face and in the foreground, a metal ladder descends down a steep slope. Overtop, a cable disappears into the trees. It's part of a funicular system to safely move bags of sediment down the mountain. A photo of the inside of a cave, looking towards a tiny entrance (seriously, we had to crawl in and it was pretty scary). A construction light is placed on a light brown gravel floor and illuminates a large stack of sediment bags which are piled along the wall towards the entrance. The top third of the image is taken up by the jagged rock ceiling.

I secured a really prestigious research grant this summer and am now officially two weeks into my PhD while fully funded. It took two years of work (or a decade, depending on how you count) and I would do it all over again in a heartbeat.

"So why did they all come out of the woodwork on the day the Nazi died?"

Targeting archaeological heritage is a war crime and a significant facet of genocide. It is a clear attempt to deny Palestinian identity and right to their deep connections to place. Solidarity to those in the ground trying to protect Palestinian heritage.

Alright, so I've been afraid to say this out loud, but I think after today, I can say it: In the first Battle of Los Angeles, the good people of LA County have prevailed. We beat ICE back. 1/

The people giving the classes did the best they could, I think, but they seemed woefully underprepared for my generation. A few of us had already been having sex when they started proper classes. Some had already found out they were queer. The adults didn't quite know how to handle it, tbh.
bioarchaeology.bsky.social
I was lucky to have integrated sex ed classes and while they were stil llacking in many aspects (e.g.: omission of queerness, strong focus on avoiding STIs and pregnancy), at the very least we got to avoid the weird shame-y secrecy part. We all got to go "EWWWW" at the same videos together.

As with bathrooms, we should ask what segregated sex-ed does in the first place. My memory is that it reinforced secrecy & shame. And of course hammered home the gender binary (uncontested in 1980s Ont) and compulsory heterosexuality (some cracks were showing) >

Find of the day is a gorgeous little blade made by a Neanderthal around 90'000 years ago using the Levallois technique. There is some retouching on the right side as well but the patina is very different, so we're a little unsure if that may just be damage. Once cleaned, we'll examine it! 🦣🏺
Photo of an elongated green stone tool that comes to a blunt point in the front, laying in my outstretched hand. The tool is quite dirty, so the distinctive negatives of the Levallois technique are a bit hard to make out.

Thanks Robert! I'll be posting more photos from previous years as well when I have a day off - it's a genuinely spectacular place.

Excavation is well under way! 🏺
My goal today is to lower about a square metre of soil down to a layer of burnt bone, ash, and stone tools that is visible in the profile in the second picture.
It's a Middle Palaeolithic cumtural layer left behind by Neanderthals around 90'000 years ago.
A photo of a patch of red-ish brown soil and a green painters brush. A photo os a small archaeological profile of mostly red soil with a small layer of blackened material visible around 3cm deep.

really feels like housing affordability is one of the most important political issues of our time, affecting nearly every aspect of our lives, and everyday our mainstream political discourse is about whether sour cream is woke or not

Quick snuggle break with Scott!
A photo of me squatting down on the ground. I'm wearing a pink oversized t-shirt, black work shorts and purple running shoes and have a gorgeous, fluffy australian shepherd dog snuggling into my chest. I've got my arm warpped around him ans am giving him head scritches. He lookes absolutely blissed out with his big ole tongue hanging out.

Back to my square this morning!
The burnt layer seems to disappear, but I am curious to see what's hiding under the sand in the top right part. Will report back 😇🏺
The same square of red sand, the top right corner is elevated quite a bit as compared to the rest. There may be secrets there 👀

Now I'm taking 300 overlapping pictures for a 3D model while trying to keep the lighting consistent (impossible), getting everything from as many angles as possible while also incorporating a bunch of reference points that can't always be placed where we'd like them to... 😅
bioarchaeology.bsky.social
They're really versatile, it turns out 😅
We also use them to mark the middle of a square if we need to work on a more granular level and we use them as reference points for 3D imaging!
bioarchaeology.bsky.social
I'll post some of the larger ones tomorrow! They are quite a sight ☺️

Progress from this morning! It's a bit hard to see on the image but I've reached the top of my cultural layer. It disappears towards the top of the picture and the sediment completely changes. Will be interesting to see what happens there!
Photo of the same area as in the post above. It now shows the top of a cultural layer with the sediment darkened by ash. Fragments of partially burnt bones and a few small stone tools are emerging.

It really is hard to convey sometimes 😅
Luckily our site is exremely rich and pnce those layers reveal crazy stuff like entire reindeer spines in anatomical connection, with ribs and pelvis still in place, it gets a little easier to get people excited!

Unlike other years we're not having any students on site to supervise, so I will have a lot more flexibility and can ideally show off some of the work we're doing and answer questions!

Wasn't sure I'd get to say it this year but: I'm on my way to do field work!
Three weeks in my favourite place in the world, with some of my favourite people ever. Nine uninterrupted field seasons and counting. I'm a lucky bastard!
