First, not totally exactly geology, but one of the more amazing iceberg pictures I've ever seen:
Next, an offering from Patrick Smith Photography (I had one of these before): this one won some awards and was on the cover of a photography magazine:
Finally, Marion Island from space:

PING!
Cool pics. Although, that second one looks alot more like a painting than an actual photo.
Anyone know what speed or whatever to use to catch the spray like that?
Great photos this week!
Wow! Thanks!
Always enjoy your offerings! :)
If I had to guess I would say about 1/2 to 1/5 sec shutter speed. That allows a greater depth of field and brings out the colors of the rock.
You always seem to outdo yourself every time!! Thanks.
Well there ya go again.
Gettin’ photo’s of the earth with holes in ‘em...
Here's what he says about this one:
Canon 5D
Canon 24-105L @ 105
1/6-second exposure @F8
LEE soft ND grad 0.9 inverted so that the dark part is over the water.
ISO 50

This sea arch opening in a cliff face at Pfeiffer Beach in Big Sur allows large waves to come through at high tide before a big storm. The waves often fill the entire portal to the top, and the portal becomes a giant water shotgun! The Tufoni formations in the rock are incredible and should be seen in person. The sun was only like this for about 30 seconds so I had to work fast. Fortunately, the sunlight was dimmed by high clouds and low fog but there was still enough light to reflect onto the rock face from the cliff behind the camera. Usually, it is not possible to get this shot because the sun is WAY too bright.
Backlighting off the cliff face behind the camera is crucial here; otherwise you have an overexposed portal with no detail on the rock face. Once the light was right, I waited for the water flow to become dramatic. A short exposure time allowed a little movement while retaining detail of the sea spray.
