Olympus
Olympus Cave Locations
Olympus is where many prospectors first learn Icarus cave locations. The region packs Forest, Desert and Arctic biomes, and caves sit along rocky ground, mountain shoulders and cliff lines rather than out in open flats. Switch the cave map to Olympus and leave Caves on to plot entrances before you drop.
Icarus cave locations on Olympus use in-game IDs such as R-17. Open a marker for the grid cell, cave size, ore counts and notes. Icarus caves on Olympus are dense enough that a short route plan — a few IDs along your path — beats wandering the ridgeline once the clock is running.
For an Olympus-only list with Large, Water and Deep Ore options, open the full Olympus map page. This cave map keeps the same markers so you can compare Olympus against Prometheus, Styx and Elysium without leaving the page.
