Monster Hunter World: Iceborne’s postgame involves you spending a lot of time in the Guiding Lands. This region is a culmination of biomes from all the areas in the game connected to each other. Each portion of the Guiding Lands has mining outcrops and bonepiles that have their own drops. This feature lists every single material item you can collect from mining outcrops and bonepiles in every region of the Guiding Lands and will help you see where you can get a specific drop.

It is worth noting that the level is indicated by the colour of the mining outcrop or bonepile. Levels 1 to 4 are represented by white, yellow, orange, and red. At Level 4, a giant bonepile or outcrop spawns giving you a guaranteed drop of the highest rarity item. You will also pickup materials that aren’t used in crafting but ones that give you a lot of research points or fuel for the Steamworks from bonepiles and mining outcrops in the Guiding Lands.

This image shows four of the six parts of the Guiding Lands but showcases the different levels of bonepiles and mining outcrops.
