Clearing this location up will help you gain access to the Northern part of the map. So, before you travel to the Snowy pass, make sure to grab some pickaxes with you. There is a lot of digging to do! At least, it is a rather peaceful place to explore.
This location will introduce you to the harsh climate of the North. If you don't have enough Warmth points (learn more about Warmth here), your character will freeze to the point they are no longer able to stay at Snowy pass. Wear warm clothes, grab some whiskey, or equip a torch to stay safe!
Once you clear the road, you will become able to travel to Northern locations!
