The first link explains that when large tracts of land were sectioned off into smaller pieces and sold by the owner, then this caused problems for the buyers in determining what were the actual land boundaries of their property and then caused problems later down the road.

And I suppose that could also cause problems with one's neighbors.
Then he states, "It's like a pirates treasure map on the back of Lucky Charms."
The example he gives states that if the boundary is along a half mile of road but the property was only 100' wide, that would be an example of property dimensions that could cause problems.
It also seems to be a problem that Maine dealt with quite a few years back but doesn't seem to have been as big a problem in other states.
