Title: Desert Rock
Post by: pluton on September 08, 2017, 07:33:33
Here, a volcanic rock in the Mojave Desert of California shown partway along it's disintegration from multi-million ton mass of cooled lava into grains of fine sand. Using the GPS EXIF you can see it's location on the Google Earth of your choice.

Definitely looks alien and organic. Great lighting.

Thanks Frank.  I'm gradually building a collection of fractured rock shots.

pluton,

You don't carry a hammer and chisel with you on your hikes do you?

Dave who thinks GPS might help kids with Easter egg hunts.

Love the amazing texture as witness of the wild behavior of the earth!

Keith, Glad to see that someone else has a fascination with fractured rocks!  My work involves dating rock surfaces, so I have (literally) thousands of similar sample photos, though not all are of fractured rocks.  It's always a challenge to make the photos interesting, as well as documenting the sample.  BTW - in some desert environments you will find that rocks of about this size are preferentially fractured north-south, due to the way that tensile stresses build up in the rock interior as the sun passes overhead each day!  (https://pubs.geoscienceworld.org/gsabulletin/article-abstract/117/1-2/161/2131/physical-weathering-in-arid-landscapes-due-to?redirectedFrom=fulltext  unfortunately the full text of this article is behind the GSA paywall).

Just for fun, here are 2 more:  The first an igneous rock from Turtle Mountains in California, the second a chunk of sandstone(Chicken Wing) in Utah(GPS'd):
