About Sparse Arctic Zone

Sparse Arctic Zone reaches 43 m above sea level down to 286 m deep by the heights of its 46,236 baked slots and covers 0.29 km² of the game's biome grid. The resource with the highest expected count here is Quartz (about 215 per game), the creature is Symbiote (about 342).

A pin belongs to the area of the nearest baked slot within 30 m (3-D, so a cave counts for its own area); a pin with no slot nearby takes the biome-map class above it (2-D). Placement of pins, depth and the spawn ranking are read from the game files; the spawn numbers are a model and have not been verified in a running game.

Depth is metres below sea level, read from slot heights. Coordinates are the game's world metres, x east and z north.
