Yeah, it seems like there's some confusion here. Buried Supplies are quests obtained from the trader. They are quite easy to do actually, especially if it's tier 1 (less chance of zombies spawning). While the reward isn't really worth it, you can bang several of them out in a single day. The benefit is getting through many of them to pass off a quest tier quickly.
Buried Treasures are the maps you find in loot. IMO they are VERY worth the effort since you get a decent pile of dukes in the chest. The nice thing about buried treasures is that if you wait to open them when you are in a higher-tier biome, the loot is even better (assuming it spawns in a biome with a higher loot stage).

Does the Perception Perk "Treasure Hunter" increase the drop rate?
(Note, the Treasure Hunter tool tip does not mention increased map drop rate)
As far as I'm aware, putting points into Treasure Hunter does not increase the drop rate of the maps. I've also not noticed any decrease in the drop rate overall from previous alphas, but I haven't dug into the code to find out. In my current playthrough I went through the first 8 days or so without a single map found, but then found 3 over the course of the next several days. I believe they have a higher chance to spawn in zombie loot bags and POI final loot chests.
EDIT: I also wouldn't waste putting points into Treasure Hunter. Given the generally low drop rate of maps, the benefits are used all that much (unless you do a lot of buried supplies quests). Even then, points are often better spent elsewhere like salvage ops.
