Hello all geologists, paleontologists, and science lovers! Deck out your water bottle or your laptop with this stylized blastoid. Blastoids are relatives of the crinoids, which also has five-fold symmetry. A long stalk would connect the head of the blastoid to the sea floor.

The beautiful Red Ravine (Rapa Rosie) from the Carpathian mountains, near Sebes

Papafrangas cave is located at the northwest side of Milos island (Cyclades, Aegean Sea, Greece) , about 4 km from Pollonia (or "Apollonia") village, and right beside the very important prehistoric arhaelogical site of Fylakopi. About 7-8 years ago, during my first visit to Milos, I remember that people could go down there and swim. The last time I went there, there was a rope and a sign that prohibited the descent to the cave-beach, because the "carved" path on the rock, is too steep and dangerous. Anyway I went down there and took this photo. *TECHNICAL INFO: I lowered manually the ISO to 50, used a small aperture (f/22), an ND-4 (2-stop down) filter, a polarizer and a tripod for this long shutter speed.

Stair Hole Number of views as of 5th July 2016 = 300. Stair Hole (near Lulworth Cove on the Purbeck coast in Dorset, England) is a partially formed cove which may expand to be as large as its neighbour, Lulworth Cove, in a few tens of thousands of years time perhaps. Stair Hole is something of a geologist's dream. See how the limestone strata to the left of the Hole have 'crumpled', probably as a result of earthquake activity many thousands of years ago. It is also popular with canoeists who like to paddle through the rock arches which have formed as a result of the relentless action of the sea over many centuries. Date: 4th May 2014.
