Forgotten Vale on the other side of the Glacial CreviceEdit
Doing Auriel's Bow (Touching the Sky) at Level 38 and I couldn't find much written about this section of Forgotten Vale. These are my notes about finding my way through. I hope it's helpful.
Go North to Find the Frost GiantEdit
As you exit from Glacial Crevice, there's a path to the left (north) with a rope strung with bones stretched across the path and a Falmer on guard to fight. Jump over the bone rope and continue up the path where another Falmer waits.
You come to a gate with a chest to the right beside it, containing some gold. Go through the gate to find the Frost Giant with the Diamond Paragon, and some dead Falmers.
A dead-end path goes to the left and turns south, over an ore vein. There are only inaccessible rocks and ice beyond. There is a quicksilver ore vein nearby to the west of the gate against some rocks.
Go East to Find the Last WayshrineEdit
As you exit Glacial Crevice, you are facing southeast. There are two Falmer tents above you, up a bone ramp to your left. Going straight ahead (to the east) brings you to a complicated network of Falmer tents with criss-crossing bone bridges. At ground level, you pass two obvious tripwires and a Falmer. Take the stone ramp up to the right. There are various Falmer to fight and many chests to loot, including two open baskets with gemstones in the tents.
The tent with the mammoth skull decoration contains an alchemy lab and various potions.
Under these bone bridges there are two ore veins. At one point I fell off the bone path into two chaurus cocoon-things that burst open with chaurus fledglings.
The canyons and villages are confusing & hard to navigate To go to the last Wayshrine, you need to find the entrance to a tunnel. It's on the canyon floor at the far east end of the village but just walking straight east takes you to a dead end with some ore veins. I reached the tunnel by going up the stone ramp on the right side just beyond the claw trap trip wires, following the bone path, finding the hut with Unknown Book Vol IV, and then jumping down from the path outside that hut. There's a gate to open just in front of the tunnel.
(Update: I'm told you don't have to jump off the path; just "follow it down")
The tunnel is lined with empty Falmer huts and some chaurus. At the end is the wayshrine and the temple with the Inner Sanctum. Don't forget to draw water from the shrine if you're doing the Auriel's Bow quest.
