摘要：
A surveyor's mark and a method for forming the mark. The mark includes a stick and a head assembled to the stick. The stick is configured to be planted in a ground and the head is configured to be above the ground. The head includes a tag having an identification number. The identification number has a value which is a first code value. The stick includes a thin wire configured as an electrical conducting loop and connected to the tag. If the stick is planted in the ground and the head is above the ground, then pulling the head in an attempt to pull up the mark from the ground results in the head being disassembled from the stick and the thin wire breaking so as to open the loop which changes the value of the identification number from the first code value to a second code value.
