See if you can interpret its depositional enviroment. |

Lava Butte is a geologically young cinder cone at the north end of a series of vents radiating from Newberry Volcano. The eruption that formed the cinder cone also issued an extensive aa lava flow, seen here in the foreground near its southeast margin. Edi and Berti went exploring and made friends with a couple of the natives.
The gash in the right center of the image results from insufficient overlap in the original photos because I accidentally kicked the tripod and failed to properly reset it. I may be able to Photoshop a fix, but that'll have to wait for a day when I have more time. |

At "les Balcons de la Mescla" one can see the top and the bottem - the Verdon river flowing in deep gorges. |

Big Rocks is a city park built around a rock formation along the banks of the Paluxy River in downtown Glen Rose, Texas. The rock formation covers an area perhaps the size of a football field. No one I spoke to knew much about the geological origins of the formation. I did hear lots of tal about mystery rocks that "didn't fit," with the formations around it. I couldn't find anything online either, so perhaps a resident gigapanning geologist might shed some light...? Still and all, erosion has done some magnificent things to the rocks. Also, Big Rocks is the only place I've been where they post a warning sign about amoebas. :-) Apparently the stagnant river water can carry the organisms. |

Carbonate sedimentologists will know and love this one - it's one of the classic world-class localities for understanding the geology of Permian-aged reef complexes. |

Finally the clouds have cleared enough to get a really nice view of the range front. How many cascades can you find? |

180+ degree panorama along 12 Road in southern Rooks County, Kansas. The distant cliff formed by the cutbank of a small stream exposes the rarely seen contact between the Fort Hays and Smoky Hill members of the Upper Cretaceous Niobrara Chalk. The Fort Hays member is characterized by thick bioturbated chalk beds whereas the overlying Smoky Hill chalk is thinly bedded and rarely exposed in extensive outcrops. |
