You spawn on plains at the bottom of a valley, with ground at least 40 blocks higher in most directions, a mountain ring that peaks about 64 blocks above the floor. The standout is an Ice Spikes patch about 202 blocks away, rare and easy to reach. Snowy Plains and Snowy Taiga fill much of the surrounding area, two villages sit within about 640 blocks, and an Ancient City lies about 765 blocks west.
