Rocks...


 Guadeloupita Mesa. The orange layers (starting at the bottom) are the Abo Formation, Lower Yeso, a little bit of the remaining Upper Yeso which has been eroded and topped over by the Bandolier Tuff which is all of the buff colored rocks.

 The other side of Guadeloupita Mesa. Starting at the bottom is the orange Lower Yeso (the Abo doesn't show at all) a complete Upper Yeso which is the fine layers of darker red.  The Glorieta sandstone is the light and dark, relatively chunky layer about half the thickness of the Upper Yeso.   Above the Glorieta sandstone is layer that is eroded and looks like a bit of a slope with vegetation, that's the Moenkopi formation. (I looked up how to spell that.  The last dark sandstone/conglomerate layer is the Chinle Group.  Above that is the Bandolier Tuff. 

 In between the two pictures is fault displacement of maybe a 100 meters.  On the left everything above the Upper Yeso is gone, eroded away before the mega-volcano covered it all.

 This view is from the top of Sandia Crest and shows the Madera limestones.   These are actually *below* the Abo formation at the very bottom of the mesa in the first pictures.  But they've been uplifted to the very top of the Sandia mountains.















Purple asters on Sandia Crest.  And another picture of the layers of limestone and the weathered granite below.  The exciting part (I am assured) is that the granite is 1.4 billion years old and the limestone laying directly on top of it is 300 to 318 million years old.  There is 1.1 billion years of rock that is missing between them.
















Another shot of the Abo formation... the one that would be directly on top of the Madera and I suppose if a person dug a deep hole they'd find it there.  The Abo is a lot of mudstone and flood plain rocks with layers of sandstone between and breaks up sort of easily... the pillar is impressive, but probably won't last for many more years.


And last, more flowers.  Apache plume.

Also... I realize most people don't care AT ALL what names go with layers of rock, but I'm going to have to remember all of this so I'm mostly repeating it all for my own benefit.

Compulsion is Compulsion, no matter who does it.  This is Brilliant Theft is Theft, no matter who does it. Freedom of Association has no room in it for *private* action   that takes that away Freedom of Association. If I have a business and have voluntary associations such that I choose to serve some people and to not serve others, that might make me a jerk and it might lose me business, it might make me smart and it might gain me business, but it's got to be my choice.  If I would normally serve the current disliked minority in my shop except for the fact that if I'm SEEN to serve them by the wrong people I'll have a private campaign against me as those people do everything possible to ruin me by preventing me from doing business physically or by attacking my customers or suppliers, then I am NOT free to make those choices. Does it really make a difference to losing my CHOICE to voluntarily associate if there's a law that says I may not serve "those people" o...

How "Representation" In Fiction Becomes Toxic

  Some things sound so obviously good that they don't need to be examined.  One of those things is the idea of Representation in fiction; movies, television or books.  Entertainment where some people are conspicuously absent would seem to be an obvious problem, right?  A person doesn't have to be "woke" or any sort of feminist to occasionally watch an old television show and realize (for example) that all the scientists and astronauts in an old movie are men. It's as glaring an anachronism these days as watching a show where everyone is chain smoking cigarettes. Entertainment should reflect the diverse nature of real life and society because, in the end, fiction has to be even more real than real life.  If nothing else, it makes that entertainment more interesting to introduce characters with a variety of backgrounds and challenges. And so we're told that diverse fiction is BETTER fiction. The way that this rather obvious truth is often framed, often discussed...

Don't Look Down by Crusie and Mayer

Not really a review, just wanted to say that I enjoyed this book, _Don't Look Down_ by Jennifer Crusie and Bob Mayer. I went to Amazon to get the link and noticed that it's getting trashed in the reviews by people who have been fans of Crusie's romance novels. I can see why they were upset but I hope she continues to collaborate with Mayer because all I can say is "your loss is my gain." I'm also going to be looking for Mayer's books written as Robert Doherty to check them out. _Don't Look Down_ is a silly novel that had me laughing or trying not to let the kids see I was crying... The laughs weren't belly laughs and the tears weren't heart wrenching sobs... It was just fun. And it *was* a romance. With guns. And knives. And Wonder Woman action figures with matching "wonder wear" underwear. And the items the international terrorist was shipping to the Russian mob boss? Pre-colombian jade penises. At least two people get e...
