This page explains how to find the Gee Ha'rah shrine and solve the "Tandem" puzzle.
How to Reach the Shrine
Go to Goma Asaagh Shrine and go south. When you reach the edge of the mountain, look down to see a narrow valley. Go down into that valley and go east through it. When you reach the end, float straight down to the area below and look for a small campsite with some snowballs in front of it.
There are stone doors at the base of the Kopeeki Drifts. You need to roll a snowball into the doors to knock them open.
Pick up a snowball and take it part way down the leftmost track in front of the campsite. Throw the snowball into the track that splits off on the right. If you are having trouble, go down to the stone doors, then follow the track upward, and use the Sheikah Scope to put a pin in the location where you need to roll the snowball.
After you successfully make a snowball hit the doors, go through to find the shrine.
How to Solve the Shrine
Shoot the rope that the stone ball is hanging from. It will push down the plunger, and the bars will open. Go through.
One side of the room has a plunger on the wall, and a stone ball suspended between two ropes. Shoot the rope that is farthest away from the plunger in the wall. Then go through the bars that opened. Open the chest to get a diamond.
In the other side of the room, use Stasis on the stone ball, then shoot both ropes. When the ball falls, it will land on the plunger, and you can go through the bars to talk to Gee Ha'rah and get the Spirit Orb.
