Abstract
A surveyor's mark and a method of forming the mark. A tag is embedded in a head. The head is removably assembled to a stick. The head is configured to be above a ground when the stick is planted in the ground. The head includes a tag. The tag in the head includes an identification number whose value identifies the tag and indicates if the head is disassembled from the stick. 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 changing the value of the identification number in the tag from a first code value to a second code value that differs from the first code value.
