A columnar basalt staircase from Iceland (was actually not that easy to climb)
GUYS, I HIT THE JACKPOT. So my department is in the midst of organizing all the stuff and we’re getting rid of a bunch of rocks that we’ve had lying around in bins and LOOK WHAT I FOUND. It’s a copper ore, specifically a bornite (Cu5FeS4) vein. For reference, bornite is the peacock ore, and it’s even prettier in person than in the pic. I remember collecting little pieces of bornite from rock grab bags when I was a kid, but this piece is HUGE!

A Rose of Jericho three hours after being watered having nearly returned to is previous, alive, state!
The Rose of Jericho(Anastatica hierochuntica) is a species of resurrection plant. These plants are characterized by their ability to use Poikilohydric mechanisms which enable them to survive extreme dehydration for years at a time.
The Titanoboa, is a 48ft long snake dating from around 60-58million years ago. It had a rib cage 2ft wide, allowing it to eat whole crocodiles, and surrounding the ribcage were muscles so powerful that it could crush a rhino. Titanoboa was so big it couldn’t even spend long amounts of time on land, because the force of gravity acting on it would cause it to suffocate under its own weight.

I have to admit, I am a bit obsessed with Popocatépetl. Probably because I lived with its view for a year.
This morning, 1/9/20, it had another great explosion.

Heidi Gustafson, who has spent the past five years collecting and working with ocher, walks along Whidbey Island’s Double Bluff Beach, off the coast of Washington, in search of the material. She came to scout this area, where she spent time as a child, after recalling its interesting cliff exposure.Some ochers, Gustafson believes, are calling out to be turned into a pigment. Others are more resistant. Those ocher fragments are either returned to their point of origin, or, if Gustafson cannot get back there, placed outside in a stone graveyard of sorts that she has created in the forest near her cabin. A few of her ocher-based artworks hang on the wall.

Forecasting the Weather 2: Clouds
Hello lighthouse keepers, sailors, fishermen, and even pirates! I recently made a post about predicting the weather while at sea. I mentioned in the post that clouds can also help predict the weather, but didn’t include them for brevity, but I did say I’d make that post another day. Well, today is that day! Consider this your guide for using clouds to anticipate the storms before they happen. (Pictures correlate with the word above them)
Fair Weather Clouds
Cirrus (see-ruhs) clouds are thin and wispy due to the wind blowing them around the sky. They look like this:
Cirrocumulus (see-ruh-kyoo-myuh-luhs) clouds are thin, patchy, and generally rippled or poofy. They generally come out in the winter. They look like this:
Altocumulus (al-tow-kyoo-myuh-luhs) clouds are rippled, fluffy and layered, the layers ranging from white to greyish. They look like this:
Cumulus (kyoo-myuh-luhs) clouds are what you think of when you think of clouds. They’re big, puffy, and come in lots of different shapes.
Stratus (stra-tus) clouds are thin and sheet-like, and always white and will generally cover most if not all of the sky.
Stratocumulus (stra-tow-kyoo-myuh-luhs) congregate in honeycomb-esque shapes, and they are patchy white or gray in color. Though these are fair weather clouds, they can indicate a storm is on its way.
Rain Clouds
Cirrostratus (see-row-stra-tuhs, sur-row-stra-tuhs) clouds also cover the sky, and can cause the halo-ing effect that was mentioned in part 1 of this post. Rain is probable within the next day.
Altostratus (al-tow-stra-tuhs) clouds are grey, cover the sky, and mean continuous rain.
Nimbostratus (nim-bow-stra-tuhs) clouds are big, puffy, gray, and thick. They’re often so thick they can obscure the sun. These also indicate continuous rain.
Cumulonimbus (Kyoo-myu-low-nim-bus) clouds are high, towered, puffy and white. They indicate upcoming thunderstorms and are generally accompanied by other cumulus clouds.
Sorry for such a long post but the pictures were necessary! Hope this second part is a good supplement to part one! Have fun keeping your eyes on the skys!

When you see Moraine Lake for the first time in person 😍😍
.
I still remember being in complete disbelief of the actual water color of this beautiful Canadian lake! Today I’m excited to be headed to upstate New York for a few days in search of more awe and more lakes aha 🙌

Hi, it’s been a while 👋🏻😊 My first-ever ‚pool walk video‘ to a nice golden morning view of Mt Pilatus, watch until the end🏔☀️. Got up really early but it was worth doing.

Deep magma reservoir below Mt Rainier
Researchers from Norway and the US have mapped an 8 by 16 km magma chamber at 8 km depth below Washington State’s Mount Rainier. The detailed map was created by measuring the variations in the magnetic and electrical fields as well as seismic imaging. Researchers suggest that this map could help us predict when volcanoes will erupt.

I love plants... I don’t know if they are appropriate for summer/august time but oh well. I still think its quite adorable
In a first, scientists have discovered that the marine algal species Nannochloropsis oceanica can live inside the fungus Mortierella elongata. The species formed a mutually beneficial relationship in a lab dish.
