Iron Marches: Level 50-60
In the highlighted area on the image, near the “Granite Front” in the Iron Marches zone you can kill many mobs that repeatedly spawn. You will also find 2 weapons on the ground which can be used to spawn sniper rifles, which deal 4,500 damage and up.
Timberline Falls: Level 50-60
Here you will find many, roughly 6 to 9, spawns of Cauliflower. Aside from gathering the cauliflower, you will also get a fair amount of XP per gather. Right below that point on the map, there is a cave with a Rich Platinum vein in it as well. To get there, simply travel to the Thistlereed Waypoint in Timberline Falls.
