A1: There is not one you climb. here is a entire guide of what to do and how to do itThe next cut scene shows Norse remnants underneath the Shiva temple. Nothing remains on the pedestal. The gauntlet, which was supposedly there, is gone. Looking at the walls, Lara notices an ancient engraved map that has been recently destroyed. According to the runes, the map was leading to Thor’s belt and hammer. Turning around, Lara inches closer to the pedestal and makes a rather peculiar discovery: the initials "RJC" have been carved into the stone, along with information about the gaunlet. "RJC" stands for Richard James Croft, Lara’s father, but he never used his middle name to avoid confusion with his own father. With this clue, Lara understands where her father hid the gauntlet. She decides to head back home.
[Checkpoint] Room with Thor's statue and central structure - The circular platform you are stating on and the walkway you crossed before is an entire wall mechanism that can be rotated. The goal here is to rotate the wall (and the walkway) towards the opening opposite the entrance which is the exit.
Aligning the walkway with the exit - (The entire process is shown in this page.) Hang from the edge of the circular platform. Release many times to grab the handholds below until you reach the circular ledge. Grab the panel in front you and move to the right as much as you can. That way, you move the panel and the entire wall.
Go left and jump over the gap. Go around the ledge until you reach the end. Jump to grab the horizontal pole, swing and jump to grab the next one. Again, swing and jump to grab thethird pole, then jump to the walkway ahead.
Turn right, grab the wall and start pulling it. Keep pulling until you pass the third pillar on the left. Stop somewhere between the third and fourth pillar. That way, you will leave some space for Lara to go around the wall and reach the other side (behind the wall). Do that, grab the wall and push it to the end (until Lara stops).
Turn left and jump to grab the horizontal pole. Swing and jump to grab the next one. Again, swing and jump to grab the third pole, then jump to the walkway ahead. Go to the left and jump over the gap. Grap the panel again and move to the right as much as you can.
The brief cut scene shows that the walkway has been aligned with the exit.
