Chasm Ziggurat - Scaling the Ziggurat - Part 4

As you move toward the opening on the right...

...a bolt of lightning hits the cliffside, breaking off large chunks of rock and revealing a patch of climbable rock.

Stand near the anchor post and shoot a rope arrow into that part of the cliff.

Zip up the line and latch onto the wall with your axe. As you do this, another lightning bolt zaps the cliff wall below you, revealing more climbable rock.

Climb to the left, above the huge statue of Queen Himiko. Jump across the gap in the rocks and latch on to the next climbable section to the left. Climb down as far as you can.

Then press Dodge/Drop to let go and fall.

Quickly press Interact to latch onto the rock face below. Here you'll need to press Interact again, in time with the on-screen prompt, to prevent Lara from losing her grip.

When you've got a firm hold, continue climbing around to the right and into the opening above.

At the top of the steps you'll find the Ziggurat Vestibule Day Camp. No more fast traveling allowed for now, but this is a nice spot to rest and top off your ammo if necessary. There are boxes of pistol, rifle/SMG and shotgun ammo sitting on the floor near the campfire.
