Each of Fallout: New Vegas’s main story DLCs has a collectible snow globe the player can pick up and add to their collection. In the case of the Lonesome Road DLC, the snow globe can be found near the Junction 7 Rest Stop close to High Road.

Quick tips before you set off to get the snow globe:

• Lonesome Road DLC required. To get this snow globe, you need to have the Lonesome Road DLC installed. 
• Added to collection instantly. Unlike the snow globes from the base games, the DLC snow globes are added to your collection at the Lucky 38 instantly. This also means that you are immediately granted the 2000 cap reward for finding it.

Acquisition

To acquire this snow globe, head to the Junction 7 Rest Stop, you’ll pass through here during the main quest “The Launch”.

Once there, you’ll see the road split into two directions – left (going uphill) and right (going downhill). Take the path to the right and go downhill.

You will pass by a broken-down sign. Keep going downhill until you reach a dilapidated brick building.

The entrance to the building is on the far end of the southern side of the building. Head inside, and go up the stairs directly in front of you and go up to the second floor.

Round the corner and you’ll see a fallen shelf in the back of the next room, approach it.

The snow globe is in that shelf. Note that when you pick it up, tunnellers will spawn outside.
