I don't know if anyone is still playing 1.2.2 like I am, but I just learned of the splashed down biome science myself and have been on a mission to find them all. I too found the Mountain one via the steam post. And now thanks to this thread I finally found the elusive Highlands one, so yeah big thanks for your patience. I flew up and down the banks of that river myself and found nothing but Shores, so I'm curious to find out how small it is haha.

Speaking of this lake to the north with the Mountain biome, (which I'm now calling Biome Lake) it has quite a few other splashed down biomes. Tundra, Ice Caps, Grasslands, Northern Ice Shelf, Shores, Water, and ofc Mountains. Most of them are along the east and south east shoreline, with Mountains and Water being a little further off the coast. The lake is only missing Badlands, Highlands, Desert, and Southern Ice Shelf, or I just couldn't find them.
Speaking of the Southern Ice Shelf biome, if you look a little to the north/north east of Biome Lake, you'll see another small lake just south of the Northern Ice Shelf. It has a very tiny Southern Ice Shelf biome at the northern end of the lake roughly in the center. The biome is partly in the water and on land so you can grab both the landed and splashed down science and save a trip to the south pole. And I suppose if you're quick enough you can fly over it and grab the flying above science as well. Coords: N 72-56-25 W 82-59-00
I'm off to investigate an island just south east of KSC that supposedly has a water biome on land to grab some water landed science xD.
