Speak to Captain Gilles

Speak to Captain Gilles and learn about the killings that have been happening around the refugee camp. This will automatically start the Climb Ev’ry Mountain Side Quest.

Find the Source of Attacks on Bitter Springs

Follow the marker on your map and hike to find a cave near the top of the hill. Upon entering the cave, approach the man inside to meet Oscar Velasco. Here, you will have to decide between killing him or convincing him to leave the refugees alone.

Kill Oscar Velasco

If you choose to fight Oscar Velasco, he will immediately engage you in a shootout. Although the cave is very small, there is a narrow pathway to your right that you can use to flank him and get close. After defeating him, you can loot the Great Khans Supply Cache Key from his corpse to access the contents inside the cave.

Convince Oscar to Stay Away

Alternatively, if you have at least 50 Skill Points in Speech, you can convince Oscar to stop attacking the refugees, and you will have to propose a solution.

Continue Your Convesation With Oscar

Continue your conversation with Oscar and discuss a solution for what he should do instead of attacking the refugees to stop the violence.

Ask Oscar to Rejoin the Khans

You can convince Oscar to settle down and rejoin the Khans at the Red Rock Canyon. This way, he will stop seeking revenge and will surrender peacefully. Additionally, he will willingly give you the Great Khans Supply Cache Key if you choose this dialogue option.

Tell Oscar to Attack Camp McCarran

You can suggest to Oscar that he should attack Camp McCarran instead, directly targeting the NCR faction.

Return to Captain Gilles

Return to Captain Gilles and tell her about Oscar Velasco to complete the Side Quest.

Best Choice for Climb Ev’ry Mountain

Convince Oscar Velasco to Rejoin the Khans at Red Rock Canyon

Although it requires 50 Skill Points in Speech, it is recommended that you complete this quest by convincing Oscar Velasco to settle down and move to Red Rock Canyon to rejoin the Khans. This way, you can avoid fighting anyone, and you will receive the Great Khans Supply Cache Key for completing the Side Quest.
