Another seed with wolves!

This seed has lots of trees, some mountains, caves, and I also found a mineshaft with a monster spawner. Aaaaanddd some wolves in the forest....

The last screenshot with moss blocks has the spawner,  I already broke it tho.. 

Mineshaft coordinates:

X: 519

Y: 44.6

Z: -51.7
