I’ve posted about the Great Unconformity several times now (and you still must capitalize it), and had the chance to see when visiting the Red Rock Canyon Conservation Area in Las Vegas.
After almost 5 years, I didn’t trust I’d be able to find it again. I decided to search Google maps and sure enough, there it was. Thank you to the wonderful person who put it on the map, and thank you Google for adding it! See the location below.
In the last picture it is in the rocks near the left of the picture where the trail can be seen and the metal sign is standing (zoom in). They are the same rocks layers known as the Great Unconformity at the bottom of the Grand Canyon in an easily accessible part of Las Vegas. You’re welcome.
The Great Unconformity

Refresher:
Tapeats Sandstone - 525 million years old
Vishnu Schist - 1.7 billion years old
Time Gap of 1.2 billion years = The Great Unconformity
The crazy vivid colours of an Azure Kingfisher just before sunrise this morning
We followed this one as it worked its way upstream, finding a new perch after each dive into the river. Despite these bright colours, they're surprisingly difficult to see when they're not moving
If this insane ruling by the Texas judge is allowed to stand, any drug could be open to being removed by a judge overriding the FDA. And it could go the other way as another judge could literally tell the FDA to approve an unsafe or ineffective drug because a drug maker or a citizen wants it available. This judge is not qualified to overrule or second guess the experts, scientists, and medical professionals on what is a safe and effective medication after intense scrutiny and rigorous testing. And if this stands, what will happen to other regulatory agencies in this country if someone, say, doesn't like the fact they cannot dump sewage in the ocean and sues in court to override the clean water act so he can dispose of his raw sewage in the nearest river or ocean? The ramifications of this ruling could be wide-reaching and devastating to everyone.

For those of you who might be wondering - here are the original photographs that the two Polaroids above are derived from.
These were shot on very expired Ektachrome E100G on an overcast winter day, these are the colours exactly as they came out on the original slides!
You can 'correct' the colour on slides like these but honestly I like them just as they are If I wanted accurate colour I'd use fresh film!
Purple us my favorite color for fluorite. This specimen fills the bill and then some.
Locality: Yao Gang Xian, Hunan, China.

A mighty fallen #ThickTrunkTuesday at UVM's East Woods Natural Area. Most trees in the area lie where they fell, but this one was sawn to provide passage for trail users. I like that we can see the scar where two trunks grew together.

Fluorite, CaF2 - blue crystal

Shiny and elusive, featherlight and golden-brown. How would you describe Pele’s hairs? But don’t be fooled. These are strands of volcanic glass & can pose a serious hazard. #HVO #VolcanoWatch: usgs.gov/observatories/hvo/n…

Interesting #geology I just learned about along the Salt Lake/Utah County line (and further east toward like Park City) with the remains of stratovolcanoes near Heber City.
