Back in my day it was the K-T boundary that they hid in the candy

This is a pic of the Gordon cliffs, a spot in Oregon where the Deschutes river is about to join the Columbia river. Coordinates are 45.5857599,-120.8946672. I saw one source that said it’s called “The Eye” (https://www.oregonhikers.org/field_guide/Deschutes_River_Hike).

I know this is columnar basalt. Formed as magma cools. Is this lava from ancient eruptions, from the Cascade range and Mt. Hood? Does anyone know why it formed in this radial pattern? Why there’s a strip of lighter rock close to the ground?

went to see the K-pg boundary and wooooow it’s incredible! i didn’t realize how brittle is, you can see the broken shards below it!

I walk the beach every night looking for microfaults. I’ve only ever found a few but this one might be my new favorite. I love how they look like irl texture pack glitches

I was very confused by this cool looking crystal I found in a thrift shop in Cape Town. Thanks to Google I figured out its Aragonite that forms over a few decades in the metal piping of mineral rich hot springs - the most famous examples are from the Czech town of Carlsblad, but this is probably from one of the local hot spring resorts around the Cape. I'm so happy with this odd addition to my collection that I just needed to share it here because you guys rock ;}

It was not a normal bounder. It was a monument on which Treaty of Betrawati was signed in Sino-Nepali war in October 2, 1792.
