The Carved Wooden Ghurra is the seventy-ninth treasure that can be found in Uncharted 2: Among Thieves.
The Carved Wooden Ghurra is found in Chapter 22 - The Monastery. This is a fairly obscurely-hidden treasure. Once the player has crossed the previous bridge, the one which is accessed after the locked door blows open, the player should look down and to the right. Instead of going forward into the next tower, the player can drop down onto a series of bricks below. Hanging from each, they can work their way lower and lower until they reach the actual location of the treasure, sitting on a brick next to one of the bridge's support beams.
