Hidden in the gravel

It looks like it is, an idyllic lake at noon and at night.
Previously several years back, it was a huge gravel pit.
An example that some raw material extractor takes responsibility after “harvest”.

Not a golddigger even many contractors mention gravel
– with the same awe as others do with gold.
Huge amounts of gravel are used worldwide.
Many gravel pits resemble pure lunar landscapes while in use.
Some do it after use too, where nature most of all seems abused
– but many are recreated as agricultural or recreational purposes.

This monster with a total weight of fifty tons,
only two shovels of seventeen tons each will fill the largest contractor trucks.
