Great Lvl 40 Grinding Spot?

So I was looking around nesaak for a good place to grind and came across a cave that I've never seen before in game or on the forums. I went inside and almost turned back because I thought it might just be the ice barrows entrance, but decided to go further just because.

When I reached the bottom, I found a cave with a bridge - around the bridge, a Ton of Hungry Wendigos spawn - and across the bridge was a cave with a "Crazy wolf tamer" and like 8 wolves that spawn constantly. Inside there are some ice spikes that you can jump up on to avoid getting hit (There's a lower one that all classes could jump on, but I got hit off a few times by the wolf tamer), and there's a taller one that archer / warrior could get up on to avoid being hit at all. Inside this cave I went from lvl 46 to lvl 47 in under 20 minutes *Which was a Major difference from what I have been doing*.

I don't know if anyone's put this on forums before, because I've never seen it lol.

The coordinates to the cave entrance are:
x: 180
y: 71
Z: -710

Happy grinding - Wheat

 

This is wolf den. It's been mentioned many, many times, but great job finding it anyways

 

Oh, thanks lol. As i said i'd never heard it mentioned Anywhere nor has anyone pointed it out to me in game when asking for grinding locations xD.
