Quick Facts

• Quest Type: Use item at cave entrance
• Pre-requisites: Monitoring the Rift: Sundered Chasm
• Chain Position: Third and final in the Monitoring the Rift series

Walkthrough

Cave Location: [40, 19] or [40, 20], at the back of the Winterfin murloc village on the eastern shore across from Coldarra.

IMPORTANT: The cave is NOT on Coldarra. It’s on the mainland, on the eastern edge of the water separating the mainland from Coldarra. Approach from the east, not the west.

Getting There

Option 1: From Amber Ledge (Swimming Route)

Take the cliff trail down to the water at [47, 28]. When you reach the murloc encampment, swim across to the cave at [40, 20].

Option 2: From Fizzcrank Airstrip (Faster)

Fly to Fizzcrank Airstrip, then head straight west. You’ll come to a path leading northwest, which descends to the water directly across from the beach below the cavern. This route involves less swimming and is generally faster.

Option 3: Cold Weather Flying (Easiest)

If you have Cold Weather Flying (available at level 77, or earlier via the BoA tome), you can fly directly to the cave entrance or land on the rocks above it. 

Using the Arcanometer

Positioning is Critical:

Unlike the previous two anomalies (which had visible purple glowing effects), this location has no obvious purple marker. Instead, look for:

• Falling dust and small rocks from the ceiling
• The point where the area name changes to “Winterfin Caverns” on your minimap
• The torches at the cave entrance

Where to Stand:

• You need to go past the torches at the cave entrance
• Stand on the rock floor of the cave (sand outside won’t work)
• Stand right under where the dust is falling
• The Arcanometer will NOT work if you go too far inside OR stay outside

Dealing with Murlocs

The cave is in hostile Winterfin Village territory. Options for avoiding combat:

Minimal Combat Approach:

• Approach from the southern tip of the beach
• You may only need to fight one murloc to reach the cave entrance
• Take the reading just inside the entrance and leave immediately

No Combat Approach:

• With Cold Weather Flying, land on top of the cave entrance
• Use the Arcanometer from above

Quest Pairing Opportunity

If you’re already heading to Winterfin Village, consider picking up the murloc questline from King Mrgl-Mrgl at Winterfin Retreat. Several quests can be completed in the same area:

• Them! (kill 15 Winterfin murlocs)
• Oh Noes, the Tadpoles! (free 20 tadpoles)
• Keymaster Urmgrgl (kill named murloc inside cave)
• Escape from the Winterfin Caverns (escort quest, save for last)

Efficiency Tip: Complete the Arcanometer reading at the cave entrance, do Keymaster Urmgrgl deeper inside, then pick up the escort quest on your way out.

Story Context: Garren’s Report Complete

Garren is businesslike as he sends you on this final errand:

“I need to compile my notes and prepare a presentation for my colleagues in Dalaran.”

“While I do, I must ask that you visit the Winterfin Cavern to the north. You must use the Arcanometer while standing in the mouth of the cavern. Return to me at once when you have the data. My documentation will be incomplete without it.”

Upon return, Garren’s work is done:

“Excellent, this completes my report. I’ll be sure to mention your kindness to the council, <name>.”

Lore: The Caverns and the Murloc Madness

What Garren doesn’t know is that the Winterfin Caverns aren’t just another data point. They’re ground zero for a tragedy.

The Winterfin tribe is the first friendly murloc tribe players encounter in WoW. They lived peacefully in their village until recent earthquakes (caused by Malygos’s ley line redirection) exposed the caverns beneath their home. A deranged makrura named Claximus emerged and stole their children.

When adult murlocs pursued Claximus into the caverns, they were exposed to magical emanations from Coldarra. The arcane energy affected their minds, allowing Claximus to enslave them. The survivors retreated and regrouped at what is now called Winterfin Retreat.

King Mrgl-Mrgl (actually in disguise in a murloc suit) later confirms the connection: “And you say that Lurgglbr discovered that the emanations from the caverns are what caused this insanity? It must be that the magic from Coldarra is growing stronger. The Nexus War… the battle between the blue dragonflight and all of the other dragons, is spilling over. Soon, we will all be embroiled in it!”

The readings you take for Garren document the same magical emanations that drove the Winterfin murlocs mad.
