This map consists of the entire Western United States, from the west coast to the Mid-West. This is the updated map of California, but has been expanded.
It consists of hand painted biomes, important rivers and lakes, such as the Colorado River and the Great Salt Lake for example, and semi-realistic biomes. The spawn is located in Salt Lake City in Utah.
The total area of this map is about 500 km2 (200 sq mi), which easily makes it the largest custom map in Minecraft(please tell me if there is a custom map larger than this). This map will expand until it reaches the maximum 4GB world size, then i will split the map into eastern United States and western United States, which can be merged together, for those who want the full size.
Please tell me in the comments if you want to use this map on the server (It will be really appreciated for my attention of server owners to tell me if they want me to join).
Update 1: Fixed the sandstone desert
Update 2: Smoothed out the terrain and added rivers west of the Rocky Mountains
