|Lead Mine Adit|
This level tunnel, a miner's adit, has been methodically blasted and carved away. The regularity of the passage is beautiful, and in its flooded state, quite magical.
The lead mine joins a natural limestone cave fanged with stalactites, stalagmites and veined with fluorspar, yawning over a subterranean lake. The chamber is spacious, with fascinating vertical shafts, all formed by the passage of water.
I only mention this because it seems writing is shaped in the same way. Having spent some time in this underworld, I can attest to the usefulness of explosives, sharp implements and relentless water. The natural formations are great, but the subterranean lake can be devalued if it is filled with the rubble from blasting out the lead mine.
