While exploring the desert Steve stumbles upon an alluvial flood plain with a small village. Steve decides to build a tree fort with a view of the surrounding area. I started by discovering the desert map is located in a plains biome. Which lead me to go with the pond/alluvial flood plain. I set the pond on one of the depressions in the sand, surrounded it with grass, mapped put the dry rain run off channels filled them with sediment. I built an ersatz npc village, and planted crops. This would have been more realistic if the map were made in a desert biome rather than a plains biome. The grass would look better brown.
