Phonolite Hill

[clayhaus]

Infrared image of a hill, in a remote section of Utah, named Phonolite. Had to look this one up: Phonolite is a rare igneous, volcanic (extrusive) rock of intermediate composition, with aphanitic to porphyritic texture.The name phonolite comes from the Greek meaning (more or less) "sounding stone" because of the metallic sound it produces if an unfractured plate is hit, hence the English name clinckstone. From Wikipedia. Interesting stuff and I like the comp with the reeds.
