Head northwest of Clue Bottle #14 to find another large skeleton. A Clue Bottle rests next to it.
On the same ledge is a bird's nest with the next bottle.
South of this nest is a geyser. Paraglide into it to shoot into the Clue Bottle high in the air.
Head to the northern area of the map to find a series of tightropes. This Clue Bottle bops atop them.
Just southwest of Clue Bottle #22 is another geyser. Paraglide into it to reach the Clue Bottle nestled in the tall fossil nearby.
Near Clue Bottle #22 is a safe spot to drop into the map's lower area. Down here, you'll find a bridge. Ride a flowing chunk of ice under the bridge to find another bottle.
East of the bridge is a very tough-to-spot Clue Bottle floating in the eye socket of an upside-down mammoth skull.
Just south is a tall rock that holds another Clue Bottle. The best way to get there is to use the paraglider from a higher ledge.
Return to the bridge and follow the edge southwest to find a spine protruding from the water. Hop across the vertebrae to find a bottle on the other side.
Cross the nearby bridge and follow the path as it loops around. You'll spot a Clue Bottle behind a cave column as you do.
As you continue along the path, you'll reach a tightrope that extends over the river with the moving ice chunks. Cross it to find a massive spine protruding far out of the water. Hop up the extended pieces to reach another Clue Bottle.
Return to the ledge where the tightrope started and continue following the path as it heads southwest. You'll find the final Clue Bottle hovering above a toxic pool.
Return to the bridge near Clue Bottle #27 and take the path south, where you'll find the Safe in a dim cave. Opening it will net you Clockwerk's Eye, which displays Clue Bottles and Safes on your mini-map.
