I recently did one actually. The map was for S-Badlands. What dropped was a turqoise, 2X radiant crystal dust, a mold, a cloak that dhad +5 WIS +20 mana Healing increment 2 and a necklace that had HP/mana + 15 and alteration+2. (I could be mistaken but thats everything that dropped if i recall right). And it was lvl 20-29 treasure-map.
