a bit late but wanted to revisit an unfinished sketch for today

happy trans visibility day, lets keep fighting for eachother

See that white layer in this hillside? That's an extremely important white layer. 680,000 years ago (give or take), a large volcanic system in what is now Wyoming erupted catastrophically, spewing ash and debris across the North American continent. You might have heard of it, it's called Yellowstone Caldera. You may notice that these pictures in no way resemble the verdant forests of the Rocky Mountains and that is because they are from Death Valley, California, located more than 620 miles (1000 km) away from the Yellowstone Caldera!

But... it gets cooler.

The hills this ash layer is exposed in, the Kit Fox Hills, have been uplifted. The mudstone and sediments here are ancient valley fill, meaning that they used to be the bottom of the valley and are now about 400'/120 m above the current valley floor. This is the action of the Northern Death Valley fault zone, one of California's longest active faults. In this area, that fault has some excellent outcrops as seen below.

Next door to Death Valley to the west is Panamint Valley. It's not quite as big or dramatic as Death Valley but it has many of the same sorts of geologic features which have formed over a shorter geologic timeframe, interestingly. The faults in Panamint Valley just move faster than those in Death Valley so things are a little more youthful over there. In the middle of Panamint Valley, we see this same Yellowstone ash layer but with a caveat - instead of a mere 400 feet, in Panamint Valley that ash is more than 500 feet above the valley floor! That suggests that the valley subsidence of Panamint Valley is about 20% faster than Death Valley. The true story is more complex than that, but it's good as a reference point. Let's see what that looks like.

It's hard to see in this aerial imagery, but near the top of this steep escarpment is that same volcanic ash layer. It's a bit thicker here because this big pile of material I've outlined is an ancient delta. Panamint and Death Valleys have repeatedly hosted large lakes during cooler and wetter times. This huge delta deposit is over 1.2 million years old at the base, and about 600,000 years old at the top (above the Yellowstone ash). As the Panamint Mountains (background) rose and the valley subsided, huge amounts of eroded rock and gravel were dumped on this delta. So what you're looking at is a 1 million year-long record of the floor of Panamint Valley! How cool is that?

Cringetober Day 3 - Oversized Weapon!

Perfect opportunity to revisit my bat-wielding beast girl, Delta! Shes coming to hit you >:3

this was her design FOUR YEARS AGO... hoooly. I've really not used her enough at all cuz shes awesome. She may be friends with deadmeat wink wink :3

ohhhhhhhhhhhhhhhhhhh u wanna pet them so bad

Oof, took some time to label these and touch up some rough spots. But here it is, the Mazon Creek #paleostream piece. This was, again, a piece that barely scratches the surface.

Mazon is a Carboniferous Lagerstätte and preserves hundreds of species, one could fill whole books with scenes like these. Biggest challenge was that we have two distinct faunas, the marine Essex biota and the terrestrial Braidwood biota. Some marine animals might be able to venture into freshwater but usually the two don't mix much so I had to find a way to transplant a piece of fauna into the other. We settled on a natural raft, the likes we still see today.

After storms or floods, mats of vegetation can drift out to sea and carry with them whole communities of organisms. On the other hand driftwood is often used by marine animals as shelter so from both sides we have reasons for animals to be here. As you can see in this size chart by Discord member JW, there is much more one could have added.

But I leave that part to YOU if you are inclined to pick up where I left off ;)

HEY!! do you! yes you! want a real life mariza to hug??!!!

then please go and support @shandzii 's campaign on makeship! were almost reaching the amount needed to make the prototype!!

you can throw her against the wall!! or put her in a blender!! but she must be real first, so please go and pledge if you can!! we can make this real!!
