Head to Quicksand Caves through the Western Altepa Desert entrance at (D-12). To get here, go to the far end of the visible map at C/D-11 then follow the wall where you will soon enter a hidden tunnel.
Talk to the Goblin Geologist to receive some dialog indicating that he has placed markers onto your map.
There are nine green markers on your map spread out across the Quicksand Caves areas.
There are many new ??? spots in the caves, which ones you have been assigned appears to be random.
The markers will remain on your map until you complete the quest.
The markers are under the markers tab in your map view.
For those who use multiple PCs. The markers will only be available on the PC you talk to the Goblin Geologist on.
Explore the area and examine each of the ???s marked on your map.
