Generate for me a description of a secluded setting inside a cavern with a timber, trench, cavernous opening, and mine works.

The dull grey granite gives way to redstone as the tunnel widens and descends. No toadstools light the area, and the way is barely visible. To the south a timber extends across a wide trench that traverses the floor from wall to wall, while to the north a cavernous opening allows entrance to expansive mine works. A bit of light filters in from both ends, but hardly enough to do any serious work by.
