I'm playing the second episode of The Long Dark / Wintermute and my map has some cache locations marked on it that might have useful resources. However my experience of travelling in bad weather cross-country is that it is easy to get disoriented.
Obviously the map doesn't show you current location as that would be too GPS-like and electronics are all dead.
I guess that compasses are unavailable as they would be unusable due to the geomagnetic anomaly. This makes it impossible to work out which direction you are facing - apart from when a familiar landmark is in clear sight.
How can I find my way to a cache on the other side of the map without severe risk of getting hopelessly lost - especially if weather deteriorates.
