Here are map locations of those ones I noted while collecting two whole sets (map file: eastwastesshard.txt).
They were mostly confined to the two northern camps (where Drummon Coldshanks and Corbin Blackwell spawn) and the eastern camp (where Chief Ry`Gorr spawns), but there were a few outliers as well (one in the ruins in the north-central part of the zone and one in the central part of the zone in the middle of nowhere).
This won't be exhaustive, but might help get you started.
Oh, and some of them spawned in the campfires, so look closely. Not easy to see!
