Digging through the archives.



From a trip to Galveston, TX in my previous life. A piece if volcanic lava I picked up on the beach. Seems the Gulf of Mexico has had quite a bit of volcanic activity in it's dim history including the asteroid that brought the extinction of the dinosaurs.

At any rate it hung around for a long time before presenting itself to me. I feel honored . . .

And well photographed! The different colors makes me wonder what different kinds of materials it’s composed of.

On the same trip I found a piece of coal along the same beach. The heavy crude buried underneath the gulf gets squeezed out by the tons of water pressure so there is always a bit of seepage even without the catastrophic leaks like the BP Deep Horizon (and others). Over time -- lots of it -- the light hydrocarbons dissolve or evaporate and leave solid coal behind.

Perhaps I'll post a portrait of that later as well.
