Yellowrock National Forest is the second map of the Maine region in SnowRunner.
Where the starting map of Maine, The Lowland, is already challenging in terms of fuel and cargo availability, this map ups the difficulty further. There are no garages and trailer stores, and few scattered fuel trailers. The fuel station on this map is only available after completing a mission.
Even when the player has secured their fuel supplies, the missing bridge on the main road results in long detours. Delivery of many units of cargo are required to fix this bridge. They can then get to work on opening up the two locked gateways, as well as a central watchtower locked behind a mission.
