Shades of Green
Explorer
Several OD&D/AD&D 1E adventures, such as X1: Isle of Dread, feature extensive wilderness exploration, in which the PCs go through unexplored areas, explore them, encounter random monsters and explore mini-dungeons instead of large ones. Are there any relevant 3.xE rules dealing with exploration, mapping wilderness, wilderness adventuring and so on? If not, I'll convert the 1E/OD&D rules to 3E.
