Glacier One

Glacier One is a Space Pirate outpost on Tallon IV. The facility is located within the Phendrana Drifts region, because the cold temperature makes containment of metroids more manageable. The facilities contain a holographic Observatory, and two Research Labs: Hydra and Aether. There is also an unusually strong Metroid located in Hydra known as the "Metroid: Alpha Type", though it looks little like the traditional Alpha Metroids.

A large tank in Aether holds the remains of a failed Elite Pirate conversion, made using a crab-like traditional Zebes-style Space Pirate, rather than the reptillian caste seen on Tallon IV.

The Super Missile and Thermal Visor upgrades are obtained in the base as well.
