From left to right and top to bottom: Chalk, sandstone, brick and blue stone
Chalk is often a white calcareous sedimentary rock formed by the accumulation of skeletons of marine microorganisms (the coccolith.
Sandstone is a sedimentary rock of detrital origin formed by cementing sand grains. It may take different hues depending on its chemical composition: gray, orange, brown.
Brick is made of fired clay.
Blue stone is a sedimentary rock of varying colors (gray, blue-gray to blue-black) made of marine organisms and clay particles cemented together by calcareous mud. It is often rich in fossils.
The coordinates are those of the parking. As with all Earthcaches, the goal is not to find a box. To validate your visit, you simply go to the different indicated places. The above description will help you validate this earthcache by answering the following questions:
1- Which of the four above-described materials was not used in the building of the Church of the Assumption? 2- Which material is both used for the obelisk of the war memorial and the base of the Monument to Charles Mathieu? 3- Which of the two fossil A and B in the photos below is the biggest?
After visiting the place, log this earthcache "Found it" and send me your answers proposals either via my profile or via the Message Center. I will contact you in case of problem.
