TKKNTKKN's Nature's Pretty Sweet adds additional terrain elements, weather and biomes. It also updates the map in response to weather, giving a more wild, untamed and alive feeling to the world.

Requires a new save. Some of the weather affects might cause a little bit of lag (at high speeds or if you're really zoomed out) but you can turn them off in the options.  Map generation and your first save may take slightly longer than usual. Put early in your load order.

Most new elements will generate in the standard biomes, but there are some biomes that guarantee new features, and a few elements are ONLY available in some biomes. Most of the elements were directly inspired by places I've camped in the US.

There are also new resources, items, dangers, natural protection from raids and other effects. Resources can be harvested to get items, which can be sold or consumed.

Added:

Weather:

• Soil and sand will darken when wet. Wet sand and soil increase fertility. Deserts will see blooms after it rains.
• Puddles form after rainfall and snow melt.
• Rivers flood from rain, and are higher in the spring and lower in the fall.
• Water freezes in the winter.
• New weather:
  
  • Dust Storms (deserts only)
  • Overcast
  • Windy
    
• New Effects:
  
  • Lava Smoke
  • Frost
  • You can see pawns' breath in the cold
    

New Biomes:

• Desert Salt Flats:
  
  • Description: Desert with a lot of salt flats.
  • New plant: Salt weed, a special plant that grows only on salty earth. Separates salt from water.

    • Lava: Destroys/burns items, burns pawns. Hardens and cools into lava rock.
    • Lava rock. Plants cannot grow on lava rock, but there are more steam vents. You can mine lava rock here, and it is where pet lava rocks grow.
      
  • New building material: Lava rock blocks.
  • New terrain: Lava. Impassable terrain, but it generates heat.
  • Inspired by: Hawai'i Volcanoes National Park
    
• Desert Oasis:
  
  • Description: Lush, life filled area that is affected by desert temperatures.

If you like this mod, consider visiting the actual National and State Parks. Visitor numbers are really important, and these features all look waaaay bettter in real life :)

Future Plans: (in no particular order)

• Biome: Sequioa Forest from Sequoia National Park in California. Has huge trees that can be mined to build a base in.
• Biome: Glaciers from Glacier National Park: will expand in the winter and shrink in the summer. Can be harvested for ice.
• Additions: River Delta and flooding from New Orleans, Louisiana: River flooding leaves behind fertilizer that will make a temporary, hyper rich soil.
• Biome: Lakes from Voyagers National Park: Biome filled with water that freezes into ice in the winter.
• Additions: Cave dwellings from Gila Cliff dwellings: Ancient dwellings with loot. You can also live in them.
• Additions: Cave formations inspired by Colossal Cave in New Mexico, Florida Caverns in Florida, and Carlsbad caverns in New Mexico. Natural sculptures that are incredibly beautiful and valuable.
• Biome: Geothermal Fields from Yellowstone National Park: Dangerous biome that spawns acid, geysers and hot springs.
• Biome: Prairie biome inspired by the Great Plains. Fertile, flat land with few trees, lots of tornadoes and new animals. Add new, tornado proof area (storm cellar).
• Event: Polluted waters from Cuyahoga River: Rivers catch on fire and flood, leaving behind poisoned earth and garbage.
• Event: Resource raids. Poachers or theives will arrive to steal resources.
• Event: Wild flower bloom, inspired by the super bloom in Death Valley, California. In early spring a huge amount of flowers bloom. Gives mood bonus.
• Event: Bluebell bloom, inspired by all the bluebells in Texas. In early spring a huge amount of flowers bloom. Gives mood bonus.
• Event: Destructive floods, pawn drowning.
• Additions : Fossils, river washes, harvestable ice for coolers, more mood bonuses and take aways, etc.
