Collect Salvage to Upgrade the Axe
If you have been following my guide you will have more than enough.
Find a Camp and Upgrade the Axe
Before we upgrade the axe, talk to Whitman multiple times until the conversation is over and over until you can not do it anymore (this is part of a trophy/achievement called Chatterbox). Before heading back to camp, go north of the gate and find the Endurance Officers - Whitman: Don't Leave Me document and then go to the opposite side for the final Totem and gain the Unfinished Business trophy/achievement.
Using The Gate Base Camp, upgrade the Axe with Strengthen and open the large metal containers: one at this camp and one near the other camp (each contains 50 Salvage).
Open the Large Gate
With your new Axe in hand, head to the left gate wheel and use it to open the gate and gain 400 XP.
