Toxic Valley treasure maps

The Toxic Valley treasure maps are four maps in Fallout 76. They lead to buried mounds hidden throughout the Toxic Valley, all of which contain random valuable loot.

Locations
The notes can be found throughout Appalachia, as randomized, rare loot in containers or on the bodies of Boss creatures. The treasure maps lead to:
 * Map #01 leads to Becker farm next to the corner of an otherwise-destroyed building, by the water.
 * Map #02 leads to a mound behind the Clarksburg water tower.
 * Map #03 leads to the Pioneer Scout camp lake.
 * Map #04 leads to the cliff near the crashed space station.

Bugs
Prior to Fallout 76 patch 1.1.0.8, Toxic Valley Treasure Location #03 in the middle of Grafton Lake could not be accessed using Toxic Valley Treasure Map #03 (despite being the correct location). However, Savage Divide treasure map #04 would unlock the treasure location if it is in the player character's inventory.
