The river by the first camp now runs downhill. Fast water races down the steep glacial step with white foam streaming along it, boulders stand in it so the rapids break around them, and calmer water drifts on the gentle reaches above. The steep step pours as white water instead of leaving bare squares of riverbed.
New worlds get a planned river in the mountains: it is cut downhill into its own channel with real banks, so the water no longer drapes up a bank or sits on a ridge. Its water follows its flow, deep and calm where the valley floor is gentle, then thin and fast as it pours down the step. It has pools too: deep, calm water against the outside of each bend, a shallow gravel bar on the inside, and quicker riffles where it crosses between bends.
Your current world keeps the river it was made with, because a save keeps its land, so start a new world to see this. Still to come: darker, more natural banks, bigger waves over the rapids, and the same planned rivers outside the mountains.
