Located on Berlino/Five Stars, at 18 kilometers in height it is the second highest mountain in the sector and is notable because it draws a steady stream of climbing enthusiasts. (The highest mountain in the sector is a dead shield volcano which is far less challenging). For some two decades there has been strong competition between those who use traditional climbing implements and those using grav assist technology to see who can traverse the most arduous route to the top in the shortest amount of time. The most difficult times of the local year to climb Mount Allonsi are in the spring and fall due to seasonal wind shifts in the region.
