Copy it into Minecraft 26.3 (Java).

You start in a Grove sitting low inside a valley, with ground at least 40 blocks higher in most directions and the tallest rim about 75 blocks above the floor. That makes spawn feel like a crater. An Ancient City lies about 183 blocks south-east, and a Ruined Portal is about 217 blocks south. The nearest Village is about 319 blocks north-east, surrounded mostly by Taiga and River. Forest begins about 128 blocks away.
