Looking up from the base of the talus slope along the Presidents Trail one gets a close up look at the four presidents against an azure blue sky. |

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. |

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. |

A block 65cm by 45cm containing numerous fossil brittle starfish (too many to count) and some complete crinoids together with broken crinoid and starfish debris. This block contains a complex story about one point in time during the early part of the Jurassic, about 185 million years ago, when this part of the world was covered by a shallow, semi-tropical sea. These fossils were found near West Bay, Dorset by Sam Scriven, Earth Science Advisor for the Jurassic Coast World Heritage Site Team in November 2009. Preparation (cleaning) by Alex Moore using air pens and air abrasive. |

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