IceCap Zone (Classic Sonic's world)

IceCap Zone is a location that appears in the Sonic the Hedgehog series. It is a ice-covered Zone on Angel Island, and an alternate version of IceCap Zone from another dimension set in the recent past.

Description
The IceCap Zone is a snow-covered region located close to a large body of water. In the water are large ice floes and tall icebergs, while on land there are blocks of ice in different forms and sizes, from large and symmetrically stacked blue ice blocks to small multicolored ice stacks whose parts are shaped like diamonds and stars. There are also evergreens covered in snow.

Sonic Mania Adventures
During one winter in the IceCap Zone, Amy would drag a non-operational Metal Sonic through the Zone on her way to Dr. Eggman's lair, all in an effort to return Metal Sonic to the doctor.
