I would incorporate the following sighting rules for sighting terrain for 5 mile hexes. This based on the calculation of the horizon distance.
Clear terrain (Standing) = the hex in which the party is standing
Clear terrain (40 ft tree) = the terrain in the six surrounding hexes.
Hilly Terrain (assume 200 ft difference in elevation)
Hilly to Clear = Any clear hex within a three hex radius with no intervening mountain or hill hex.
Hilly to Hilly the same as clear.
Mountain Terrain (assume 1000 ft difference in elevation)
Mountain to Clear = Any clear hex within a seven hex radius with with no intervening mountain hex.
Mountain to Hill = Any clear hex within a six hex radius with with no intervening mountain hex.
Mountain to Mountain = the Same as Clear (tree) This is assuming in the hour of trying to sight terrain that a crag or summit is used to gain 40 ft of elevation.
Note that this the reverse is true, that standing in a clear hex one can see a mountain up to seven hexes away.
Trying to sight terrain would be a task taking about an hour probably cause at least one wandering monster check as the party roams the hex looking for vantage spots.
