Just after Christmas I said...
After the 1st of the year I will explain some of the ways the Spanish marked caches and gave directions to them.
Meanwhile guys...
if you are feeling inclined to dig a hole please don't do it under a sign.
Get a two box and see if it is worth it. the cost of the detector will save your back so much in the long run, it will be worth the money.
This combination of simple signs will give distance to cache sites.
Cache sites are almost always marked with a triangle. using the triangle is the method of finding the cache.
By measuring from the center of the corners and summing the total of the sides you will have a distance to the cache.
To achieve the direction to measure the distance the primary or motherly corner of the triangle must be determined.
Using the standard formula laid out by information Kenworthy got from archives in Madrid you will measure in a "due" direction from the motherly corner. Due North, due South, due East or West.
The motherly corner will be determined by signs read before even finding the triangle. There will be a series of three letters or numbers. such as CBA , 321.when found this way the primary corner is the #3 corner as the alphabet letters indicate numbers.
A=1, B=2 and C=3 . The first number (if all are the same size) is the primary or motherly corner.
Many times I have seen them presented as ABC with the A or the B as Very large in regard to the standard size.
I have seen the same with numbers as well. The larger number will be the primary or motherly corner.
The triangle will be laid out with the first or #1 corner being the most Southerly. The #2 corner will be the next most Northern but will be either East or West of a straight line drawn to the #3 corner which will be most Northern.
Any triangle found with no number sequence, the number 3 or Northern most corner is motherly.
NOTE: (if you are using a compass to determine due north, learn where true North is for your area, a compass uses magnetic North and that will change from year to year.)
This system follows a set of rules as laid out by Royal decree.
The Spanish adhered to it implicitly.
I would use a two box detector to determine if there is a good target before digging.
If there is no target try tripling the distance.
Another rule from Madrid says any number involving a triangle is tripled.
There are triangles that follow a different set of rules and are marked differently.
I'll discus those in another post.
You must use Spanish inches and feet to measure and you must be precise ... off by a couple feet might as well be a mile.
