Hello Kim, Good to hear from you as always,There seems to be a method on some of the things that we see, for instance on some of the yards that I have worked seems that the information that's available that's seems to be constant is that the South East portion of the yard seems to contain one part of the windrose and if its a triangle, square, rectangle ,may be in the order of drill holes, a carved box, all that is telling you its the layout of what you are looking for, information left at the knee high corner markers will reference the method of concealment ( how deep and if its a tunnel ect. NE corner ) N West may contain the direction to the other 1/2 of the windrose and the distance, I believe it to be the sum total of all the sides, and may have a multiplier ( ie small drill hole ect ) There mesurements between will be a cordell ( 189.5 feet ) or plus or minus portions of the measurements and the degrees will be true also, Information in the yard seems to be give folks something to ponder and let them show off a little, The NW corner of your windrose may contain a portion of ( probably only degrees and distance ) if you have a 330 degrees between two of your corner markers in the 1st ( SE ) part of the windrose and 189.5 feet between the same markers as the NW corner then--- bingo ---, There may be direction and distance to the next yard (S) ( 1 league distance ) an may reference something to the other yards in a distant location, turtle, fish elephant, snake, slim face guy, Or in my simple mind that's the way I see it. Have a wonderful day Keep cool. Ernie
