A view looking down towards a lighthouse with 313 stairs in the way and a setting sun

Point Reyes lighthouse was interesting. I got to see massive graded beds and a few burrow fossils. Despite heavy winds trying to push me off of the rocks!

A large outcrop of eclogite in California with a black cane leaned up against it for scale.

That’s a lot of Eclogite.
My cane for scale!

I saw some lovely bivalve fossils at the top of Mt.Diablo today!

This is cool!

California poppies growing in front of serpentinite with strongly developed scaly fabric

... And here's the state flower with the state rock: ⚒️

Large pebble conglomerate

Folded serpentinite

A cliff full of serpentinite

A green anemone in a tidal pool

That was a lot of physical demand on my body, but it was fantastic. We went to Angel Island to check out pebble conglomerates, blueschist, and a possible volcanic bomb(?)

A digitally painted scene from the Fezouata Formation featuring Aegirocassis, Sagenograptus, Falcisicaris, Bathmoceras, Rhopalocystis, Plumalina, Brachyaglaspis, Choia, Megistaspis, Eoconularia, Plasiacystis, Plumulites, Ampyx, Pirania, and a non-specific Conodont

Fezouata Formation.

Felt like drawing an Aegirocassis, accidentally drew a bunch of other stuff too.

A very, very, very very very very very very very very very, very polished fault surface reflects the blue sky

The insane, mirror-like shine of the Corona Heights Fault. ⚒️

Ribbon chert that’s been faulted

Reverse bedding seen with coal beds

Despite flight hiccups, I landed just fine!

A tabletop covered in boxes containing all kinds of fossils.

Whiteboard sketch of the two major groups of brachiopods, highlighting soft tissue anatomy (pedicle, lophophore) that doesn't usually fossilize.

Nautiloid fossil (Bellerophon?) showing internal septa dividing up shell interior into chambers. These chambers are sometimes filled with calcite spar, sometimes with sediment, and in three cases in the middle of this view, with BOTH. The boundary between them shows the paleo-horizontal, with sediment below and spar above (geopetal "way-up" indicator). Annotation shows the "up" direction (down!).

Fossils lab!

Rough start to the field course but it can only go up from here! (Literally! ✈️)

Well I guess my fears of my presentation not being good enough were for nothing. I’m proud of myself :)

A stratigraphic chart showing sedimentary layers in the pink, white, and blue colors of the trans flag. Beneath them is a drawing of an igneous intrusion with the yellow, white, purple, and black colors of the nonbinary flag.

In celebration of pride month, I give you: The gender nonconformity!

I am proud to be a trans geologist, and I celebrate each and every one of my queer peers. Happy pride!

Some neat stuff for sure, using my knowledge of lichens on the Antietam formation I determined this was a quartzite/quartz sandstone before we even chipped part of it off to be sure. And I was right!!! :)

There’s only so much I can say at a time, and I end up leaving a bunch out. So who knows?

These are wonderful phrases :)

I’m not sure if I like this style of post yet, but we’ll see as I make these if I’ll change how I’m phrasing things.

Just off I-64 near the Altoview apartments and off the trail down by the Rivanna River

We also expect to see kink banding at a depth of around 10km in what’s called the B.D.T. zone. So that tells us at some point in time there was 10km of rock above us! But there’s no mountain there anymore! That’s evidence of the former tall peaks of the Appalachian mountains.

Next we noticed there’s kink banding or kinks in the phyllite. That means this mudrock was squeezed at least twice! Once to form phyllite, and another time in a separate direction from the foliation to form the kinks! That formed during the creation of a super continent known as Pangea!

This tells me that these rocks were initially deposited at the bottom of an ocean. Now you might notice that these photo are not of the Atlantic Ocean. In fact it’s several miles from the ocean today! But at one point in time, these rocks were deposited in an ocean.

At Totier Creek Reservoir, there’s this rock we found called Phyllite. Phyllite forms when shale gets metamorphosed. Mud needs calm, quiet water to settle down. I also spotted some greywacke sandstone. Greywacke only forms in the deep ocean during undersea landslides called turbidity currents.

It was inevitable that I combined my special interests. Introducing Anomalous Prime who transforms into a stylised Anomalacaris sp. The back 3/4 of the animal is the "trailer" which I'm still working on. The bot is just the "cab". #Transformers #Maccadam #Autobot #OptimusPrime
