This seed has everything ice. Ice plains, ice mountains, frozen rivers, ice spikes, and cold taiga. You spawn right in the middle of ice plains with some ice mountains around you. The highlight of the seed is the ice spikes, though. You’ll have to travel to reach them.
This Minecraft 1.8x seed features a stronghold that intersects with a ravine. The stronghold and ravine have more than one intersection point. We tripped across it that revealed a view of the library with missing walls that exposed it to the inside of the ravine. Not far away, the end portal room hovers above the ravine with a lava flow and waterfall nearby.
This Minecraft seed (tested in the 1.8.0 update and in 1.7.10) gets the game going from spawn in an ice plain that is adjacent to a large ice plain spikes biome! To get to the ice spikes travel west from the spawn point. You can’t miss them – they’re on the opposite shore of the frozen river.
