Step well and angular unconformityThis is a really cool spot. In India, there are huge changes in the level of the water table during the year. When the monsoonal rains hit, the water table surges upwards while in the dry season it drops, with some locations seeing tens of meters of change.Step wells are dug into the ground to access groundwater. During the dry season, people walk down the steps to reach water at its lowest depths, while in the wet season the water table will rise so high that it reaches the top steps and no climbing is required. Hundreds of these wells were constructed across India prior to the British Colonial era. This one has a gorgeous feature in its wall. The rocks in the wall, described as carbonates by the photographer, show gorgeous angular unconformities. The steps follow a single layer as it heads down dip, while at higher elevation those layers are eroded and more flat-lying layers have been deposited on top. Beautiful geologic structure.When this well was constructed, apparently for the first days no water was found at the bottom. A local priest advised that the sacrifice of two unmarried women would lead the well to become productive. Eventually that sacrifice was made and shortly afterwards water actually appeared. Of course, with the variable water tables in India water was likely to appear anyway, but that doesn’t diminish the story; to this day fabric will be tied to a nearby tree in memory of those girls. -JBBImage credit: https://www.flickr.com/photos/nevilzaveri/6986395605Read more:http://www.archdaily.com/395363/india-s-forgotten-stepwells/http://www.atlasobscura.com/places/ancient-stepwells-india -- source link
