The Lost Treasure is an engaging optional side mission in Borderlands 2 that rewards players with unique loot and valuable experience. Initiated by picking up an ECHO recorder in Sawtooth Cauldron, players must track down map fragments scattered across Caustic Caverns before unlocking a hidden cache. Understanding the step-by-step sequence ensures you can navigate the environment smoothly and claim your reward without getting lost.
Starting the Mission and Tracking Map Clues
To begin the mission, head to Sawtooth Cauldron and acquire the starting ECHO recorder from a defeated enemy. Once activated, your goal shifts to collecting four distinct treasure map pieces scattered throughout Caustic Caverns. Fighting off local wildlife like threshers and crystalisks is required as you search the marked locations on your map.
The four clues lead you to specific landmarks across Caustic Caverns, including under the acid-soaked railway and inside the shore warehouse. You will also need to inspect the area in the digger's shadow and within Dahl's bloody sixth. Gathering all four pieces reveals the final location of the hidden treasure lift.
Navigating the Caustic Caverns Switches
After assembling the complete map, head to the main facility in Caustic Caverns to reach the top level. You will find four distinct levers scattered across the structure that must be flipped to activate the central lift mechanism. Paying close attention to the spatial layout helps avoid unnecessary backtracking while under fire.
Flipping all four switches in sequence powers up the elevator near the center of the facility. Riding the lift to the top brings you directly to the final control room. Clearing out any remaining enemies in this upper room allows you to safely interact with the main treasure switch.

Pulling the final switch opens the reward chest, granting substantial experience points and cash scaling to the mission level. Upon turning in the quest, players receive the unique Dahlminator pistol. This corrosive E-tech weapon fires homing darts that explode on impact, making it ideal against armored Hyperion loaders.
