Incredible rock formation on the side of Hwy 180 in Kings Canyon National Park, California.
This beautiful chevron pattern is just past Boyden Cave, near where the tours start. The rangers at the little gift shop there pointed it out to us. We wouldn't have known to look for it otherwise!
Crystals study
i'm so tired
Yes! Please keep your snails safe! (I would like to note that in my experience, some snails are too big to retract enough to stop sticking to the ground. However, take that with a grain of salt)
Keep that grain of salt away from the snails, you monster!!
oh my God i amnso sorry,,
Cumulate rock
Cumulate rocks are plutonic rocks in which cumulus minerals have been concentrated during the cooling of the magma chamber.
This sample of cumulate rock is composed by interstitial plagioclase (white), called intercumulus, and pyroxene (dark-coloured in the hand sample and brownish in thin section), called cumulus. In thin section, we can also see biotite and opaque minerals.

Hey guys! Check out this block of pure sodium that I got!
I still think Utah has to be one of my favorite places during field camp—especially due to having fantastic professors. The coal seams in the road outcrops (talking about US-6 in Castlegate, UT; srsly hop onto google maps/earth and look at them!) are jaw dropping and the outcrops are textbook grade examples of sea level changes. The crossbeds, hummockys, channel features. Made me appreciate sandstone even more.
And that's a bituminous coal seam in there with my classmates blocked out. Have a sample somewhere, though probably in pieces now...
