Jump into the boat and drive through the gate you just opened into the channel beyond.

Pull up alongside the ledge with the red flag...

...and jump out.

A gunman emerges from an alcove. Kill him and pick up the Uzi clips lying nearby.

If you don't care about getting all the secrets, you can skip this next bit and continue along the channel toward the level exit, as shown in the next section.

If you want secret #3, get back in the boat and maneuver it to the spot marked with an 'X' in the screenshot above. Position the boat facing away from the ledge with the red flag with its right side touching the ice wall, as shown in the next screenshot.

Save the game if possible. Then jump out of the boat on the left side.

Swim down into the little alcove below the ice shelf and grab the HUT KEY.

Roll...

...swim to the surface...

...and quickly climb back into the boat before Lara freezes to death.

Now drive away from the ledge with the red flag and back toward the GATEHOUSE. Turn right there.

Then follow the channel back to the WOODEN HUT in the starting area. Drive past the back of the hut, park the boat near the low ledge on the left, and jump out.

Go around to the front of the hut and use the HUT KEY in the lock to open the door. Kill the dog that rushes out.

Or, immediately after unlocking the door, press Forward + Action to climb onto the roof.

Then shoot the dog from above.

Go inside to get SECRET #3—a save/power-up crystal, Uzi clips and flares.

NOTE: If you missed either of the first two secrets, you can still get them. Check the main walkthrough for details.
