..which was in fact a penetration into an aquifer running seasonally or periodically.
Perhaps someone decided that a well would provide a more permanent supply, and dug to find the source - they should have dug sideways.....
So the first construction is based on a flawed assumption, but nevertheless provided a source of water on the plateau - sometimes.
Why was the incredibly straight DP added to the bedrock, and where was it headed?
Clearly an exploratory SLANTED shaft covers a greater number of possible well sites than a single vertical shaft.
Subterranean chamber was 'unfinished' because it didn't succeed in finding a viable water source to store.
This is where it became a different proposition.
