Survey Camp Alpha is in the southeast corner of the map. It is southeast of Watoga, northwest of Forward Station Delta, and has a chance to spawn a Bobblehead and a Magazine. It also has a sleeping bag, Cooking Station, Power Armor Station, and a few resources to be looted.
Bobblehead Location
Bobblehead 1 can be found in the left tent, in the back, on top of some boxes. The tent also has a combat rifle that can spawn, ammo box, and container to loot.
Magazine Location
The Magazine spawn is on a small table, next to the right tent. The same tent has some brain fungus to be collected as well as a Military Ammo Bag for some Ballistic Fiber.
If you’re in the area the location is worth quickly checking out. Besides the bobblehead and magazine spawn, it has a sleeping bag, Cooking Station, Power Armor Station, a chance for a Power Armor Chassis spawn, and a few resources to be looted. Some robots usually spawn here and mindful one of the robots can be an assaultron guarding the camp.
Conclusion
Survey Camp Alpha is worth taking a trip to Watoga for a bobblehead and magazine. The resources to be looted and stations to be utilized makes this location a nice rest stop. While hunting for bobbleheads and magazines be sure to check around the locations shown as sometimes the items may fall and end up nearby.
I hope this helps and as a reminder, results may vary.
