It hides us from everything !
Discovery of meteorite impact:
I have discovered them in a hole of five metres in diameter approximately, near the Elk Mountain, in the eastern Wichita Mountains, Oklahoma...
Most of the rocks around the hole are broken into small pieces; you have to walk at least two miles to find anything other than granite and 4 miles to find a dwelling...
These rocks do not resemble the granite but they are not magnetic, it's like a shocked and melted rock with a meteorite impact but it's not some very rare yellow turquoise. Turquoise Colors Colors range from shades of blue to blue-green to yellowish green depending on the amount of trace elements. Copper adds blue. Chromium and vanadium add green. Iron adds yellow. There are rare specimens of blue-violet color which contain strontium impurities. In general, US mines produce slightly greenish blue to green gems due to high iron and vanadium content.
You can see shatter cones in the second photo! The meteorite was destroyed on impact, as it fell almost directly onto the granite, and only a small percentage of the meteorite survived. 68% silicon and 17% alumina, which is quite similar to the impactites found in other meteorite craters…
I found this elk antler, in February, near the Elk Mountains (not far from Lawton)... The elk lost his antlers in the winter but not exactely in the same time.
