A stepped mine site with cranes, mine shafts, and more.
Everywhere there are entrances to mine shafts (with and without rails), piles of minerals and logs; further back there are some coal blocks and the flowing water leads to a natural cave system.
From the back, a mine car crosses a small bridge to a filling station (which doesn't work like that, but if you want, you can easily rebuild it); the crane leads down to a pit where iron ore is being mined.
During the digging one discovered "by chance" an old, overgrown temple entrance.
The cranes are based on the one here https://minecraft-bauideen.de/1027-Kleiner-Bootskran only they have a small cab, which looks like this from the inside
Next to the mine is a materials store, with blocks of coal, gold and iron, and logs of wood
And of course a small port of loading may not be missing either
