A frozen river is a variant of the river that replaces it in snowy regions.

Description

In a frozen river biome, the water is completely covered in a layer of ice. Riverbeds consist of dirt, sand, gravel, and clay, and are one of the few places where clay generates, alongside lakes, swamp marshes, ocean hilltops, and lush caves. Seagrass does not generate on the riverbed. While sugar cane can generate alongside a frozen riverbank, it often uproots itself after generation due to the water being frozen. Oak trees and grass can still generate here if this biome generates on land. Sometimes, frozen rivers can generate next to regular taiga biomes, as these are able to generate in the same temperature range as frozen rivers.
