Ranger Sarah spots the first set of Petroglyphs. These where made between 400-700 years ago. Stone chisels and hammerstones were used to chip away the desert varnish on the rock to expose the lighter color underneath.

Here is a 360° panorama captured by Curiosity at her current location, with North at center and South at both ends, on top of two large and small scale maps with her position.
There are many geological features in the panorama, can you find them in the maps?
Unlike Canned Heat (showing my age) it’s not bullfrogs but #woodlands that are currently on my mind. And feeling the need to respond to them creatively, and high on their phytoncides, here’s some #Origami#Trees made out of old #Geology#Maps superimposed with the occasional #Photo of the #Woods that inspired me. #DoubleExposure#Abstract
#China is home to around 200 #tiankeng, which are mostly distributed from the central #Shaanxi province down to the #GuangxiZhuang autonomous region in the southwest. Roughly 1/3 of the country consists of #karst — the highest proportion of overall surface area of any country in the world — compared with just under 1/5 in the United States.
View from the south to the Vercors plateau, Drôme, France. In the middle ground you can see the curved 'barre tithonique' (solid limestone of Upper Jurassic age). Behind that is the Lower Cretaceous limestone of the Glandasse (2041 m), which forms the edge of the Vercors plateau. #geology#fridayfold#foldfriday#france#alps
