A town above the lava flow (by SBA73)

Castellfollit de la Roca is a town of approximately 1,000 inhabitants in an area of less than a square kilometre, making it one of the smallest towns in Catalonia. This small urban area is bordered by the confluence of the Fluvià and Toronell rivers, between which the town’s spectacular basalt cliff rises.

The basalt crag where the town is situated is over 50 m high, almost a kilometre long, and is the direct result of the erosive action of the rivers Fluvià and Toronell on the remains of the lava flows from the volcanic eruptions which took place thousands of years ago.

The lava, once solidified, became basalt; a hard rock which takes on different forms, depending on the cooling, contraction, and splitting processes of the lava. The cliff is the result of two lava flows; the first took place 217,000 years ago, and originated in the area of the village of Batet, and has formed slabs, the second, a more recent formation from the volcanoes of Begudà is 192,000 years old, and has formed into prismatic shapes.

Looking for a piece of abstract art for the living room? Look no further than Mother Nature.  Italian geoscientist Bernardo Cesare takes photomicrographs of regular rocks, transforming them with the use of special filters into stained-glass hues. Cesare thinks of himself as less an artist than a reporter, painstakingly coaxing brilliant colors out of tiny slices of stone.

FOSSILIZED SAND DUNES: Crossbedding in Coconino Sandstone Along the South Kaibab Trail of the Grand Canyon
Photo and text by Wægen

In the early Permian Period (a few hundred million years ago) there was a great desert in the area of the yet to be carved Grand Canyon, a desert that stretched as far north as present day Montana. (This was during the time of the last supercontinent, Pangea - at the time when the northern Appalachian Mountains were pushed higher than the present day Himalayan Mountains.) Northerly winds deposited sands, creating sand dunes. The dunes would shift and move as they do today in the Sahara Desert, at times building, at times cutting down. The sand was sorted by the wind, and the quality of the sand would vary. The remains of dunes were buried in succession until a layer 65 feet deep had been laid down in the region of the present day Grand Canyon, several hundred feet deep in areas to the north. Over time, these sedimentary remains were transformed into stone. The result is the fossilized sand dunes shown above.
