Blue rune triumvirate, Snow Mountains level?

[Xenomrph]

Okay, I'm in the Snow Mountains at Parad Isle, and I've got no idea where the third blue rune is. I found the one near the maiden on the right, I found the one up on top of a tower in the back left corner, and I've got no idea where the third one is. I've checked a few different guides, which said:

After two or three lion fights, you should see some pillars on the left with chest # 51. From here, backtrack about 10 steps and notice the square shaped rock to climb up. Follow the path, drop into a building, to find blue runesand


Drop down and head back towards the slope, and you will come to a square
block that looks PERFECT for jumping upon, on the left-hand side of the
path.

Ascend this and jump up to the next ledge. Dispose of the lion, and keep
heading forward and, ultimately, around to the right where, when you land
on the platform, you will fall through to a hidden room beneath, which contains the FIRST blue rune triumvirate.I have no idea what either of those are talking about.

Go where the chest was; Then backtrack a few steps, you'll have to climb up the left wall. Careful, there's a lion on the path going to the top of the building.

Yep, from outside the entrance to the chest behind the pillars, come back towards the camera a bit and you'll see a block on the left you can climb onto. Go up and follow the path, killing the lion, and you'll eventually fall through the ground into a little room with the rune. Hit it, then the one next to the maiden, then the one way in the back.
