AS with any trail -- In My opinion --- the first thing to is to decide what the trail is for, is it water, camp, rest stop, settlement, church, Royal Trail, mines, what are you looking for, league square is the most common, possibly 80 percent will be those because every league square was surveyed Border to Border and from Coast to Coast Just in Oklahoma there ( if memory serves me ) 320 square league's in side of the State of Oklahoma, that's a lot of carvings folks, a close guess would be 20 inside and around the league square, some will be shared and noted at the site 3 / 4 directions at the corner markers.
