Read an interesting Tut trivia bit not long ago!
In many of his regalia & jewelry pieces, a pale yellow, translucent stone shows up alongside the turquoise and gold. These particular stones are called "Libyan desert glass" and have long been believed to be created by meteoric impacts, mostly in the Sahara.
Recently, someone noticed that a fleck of something black was inside one of the desert glass cabochons. Upon testing (I'm not sure what kind, those details not being important enough for the blurb I found) apparently the black fleck matches up to the chemical composition of a comet, not a meteorite, meteor, or asteroid.
I was going to put something flippant about "I got shiny rocks like you wouldn't believe" on the Nov. 4th image (Fireworks Fantasy, the $2M bra) but I can't find it in the threads after I log in, so I'll be flippant here instead.
I rockhound. I have "common" opal--which isn't common but is called so because it lacks the play-of-color fire typical of Australian opals--from eastern Oregon and several southwestern Montana sites. No, I don't have Montana agate, because it comes from the Yellowstone River drainage system and the western border of that is 300 miles east of me. I have MUCH rarer bottle-green botryoidal (bubbly-looking) agate from here in MT. I have rhyolite, most with landscape patterns, and the same in jasper, mostly from eastern Oregon. I have beach jasper and friends from the northern Oregon coast, and piles of bivalve fossils from Moolack (moo-lock) Beach State Park, the next beach north of Agate Beach, Oregon. Half or more of what I've pulled out of the river a mile or so north of my apartment hasn't been identified yet.
Also, I now have a short but fun story, illustrated in 5 photos, that might do well on the other image thread. Anyone I need to submit it to first?
