I have four characters travelling through an arctic region towards the pole. (This is a fantasy story so they have special beasts that they're riding.)
1) What, on almost perfectly flat terrain, would be the distance they could see to the horizon in each direction?
2) Assuming perfect weather, what kind of visibility is there at night at a) a new moon, and b) a full moon? Could four people riding one after the other see each other without using lights?
