Where is Snowcloak fishing hole?

I'm in Coerthas Central Highlands at X3, Y21 looking for this fishing hole but can't seem to find it.

Anyone knows how to locate this spot? Thanks for any advice!

I think that's the small hole in the ice at the camp site?

If not, then try the puddles on the glacier.

Snowcloak is those little pools right by the dungeon entrance. You're in the right place.

(the camp site is the Exploratory Ice Hole)

My fisher is level 49, and he can't find this hole. I run around the Dungeon entrance, try to cast every couple of steps, and keep getting something about "Unable to use that action at this time". I don't see any actual hole in the ice either.

What am I doing wrong?

Edit: Never mind, thank you for your input though. The hole is not at X3, Y21. It starts at X4.3, Y21.3. Every resource I looked up listed the first set of coordinates, so I kept looking around there. Doh. Now I've learned a good lesson: look wider and further, when at first you can't find it where it's "supposed" to be. LOL. Again thanks for responding, folks.
