ROUTE 3 WAYPOINT 10

Waypoint 10. Siphon of the watering can (Map of Route 3) At this point, we can see a small irrigation channel or watering can called here, which used to carry the water needed to irrigate the vegetable gardens on the banks of the stream. It is a communicating vessel, to bridge the difference in level caused by the construction of the old road from Sepúlveda to Peñafiel, built at the same time as the so-called Puentón, which we will see later. It is formed by a closed stone conduit, with a square section, which is buried under the road and rises along the margins of the same and with the same section, and once the difference in level has been overcome, it continues with the watering place made in the natural terrain as a ditch. The outlets are covered with large stone slabs to prevent people or animals from falling into them.

ROUTE 1 WAYPOINT 9 AND ROUTE 2 WAYPOINT 9

Waypoint 9: The Dolomites  Map route 1     (Map Route 2) We walk through the village and end the creation of "Hortezuelos"  that defines the depostional sequence DS-2. Even though we have finished our peculiar sequential and sedimentary analysis, the grat oscilations of the sea level during the superior Cretacic period continued to affect and generate sea rocks. To start, there are two updates to highlight, on the one hand we will no longer refer to rocks of Conician age, but of Santonian age (86,3-83,6 M.Y) and on the other hand we are no longer in the creation of "hortezuelos" but in the creation of dolomites of Montejo. This is of high relevance as we have to change our vision completely, if before we focused on the alternation between loam and chalky rocks, we now only have one dolomitic unit ( with dolomites in variable strata). Lets not forget that we are not speaking about chaly rocks, but about dolomites ( instead of  CaCO 3 , is  CaMg(CO 3 ) 2 ) t...

ROUTE 2 WAYPOINT 1

 Waypoint 1: Rudists block in front of the "Asociación"  (Map Route 2) It is a block belonging to the second bar and completely full of rudists (especially Hippurites incisus and some Biradiolites angulosus ). Curiously, on this point there must be these same rudists, the problem is that the urbanization of the village does not allow us to appreciate it. In this case, in geological terms, they are rudists belonging to the second half of the calcareous bar of the Hortezuelos Formation , in the section where the Hippurites incisus are abundant, as opposed to the Radiolites . This is due to the fact that the Hippurites have a faster growth and are occupying almost all the space.
