Geothermal Valley - Pit of Judgment Challenge Tomb (Part 3)

There's a second mine cart here, but you can't do anything useful with it yet. Mine more magnesite in the alcove on the right.

Pick up some cloth and a relic (9/13), a pair of Dice from The Athanatoi set, on the left. Then scramble up the wooden wall and climb the stairs to the top.

There's more magnesite on the outside ledge...

...and a survival cache (14/20) at the back of the alcove with the movable platform.

Crank the wheel...

...to lower the platform to the level below. Notice that as it descends the platform also rotates a quarter turn counterclockwise.

Cross the platform and turn the second wheel to rotate the platform a quarter turn clockwise.

Now you should be able to push the mine cart onto the platform.

Before raising the platform, turn the second wheel again to rotate the platform a quarter turn counterclockwise.

Now turn the first wheel again to raise the platform to the level above, while simultaneously rotating it a quarter turn clockwise.

When you get the cart to the upper level, you should now be able to push it forward down the tracks.

NOTE: If you turned the lower wheel too far, or not far enough, and the platform somehow became misaligned, preventing you from pushing the cart onto the tracks, just return the cart to the lower level and start again. Notice there are 4 wooden bumpers, one on each side of the platform. Three of these remain fixed at all times. The fourth retracts into the floor to allow the cart to pass over it. Rotate the platform until the retractable bumper is farthest from the crank that controls the rotation. Then turn the other wheel to raise the platform. It should then be in the correct position once you get it to the upper level.

When you push the cart forward, it rolls on down the tracks, crashing through the pile of debris and destroying the wooden wall in front of the codex room.
