Lola's Treasure Map

Notes : Right click this item to begin the quest. Map displays this when you click on it:

First Hint: North of Hidden Valley Mines Second Hint: West of Moongorge Third Hint: North East of Dead Tree Cave Fourth Hint: South East of Barren Caves Mystery Numbers: (50.3, 36.6)

This seems to indicate that the mound you need is somewhere near the, but that is nowhere close to.

I found at, just north of.
