- a stick configured to be planted in a ground; and
a head removably assembled to the stick and configured to be above the ground when the stick is planted in the ground,wherein the head comprises a tag,wherein the tag in the head comprises an identification number whose value identifies the tag and indicates if the head is disassembled from the stick, andwherein 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 surveyor'"'"'s 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,wherein the stick comprises a thin wire configured as an electrical conducting loop and connected to the tag, andwherein said attempt to pull up the surveyor'"'"'s mark from the ground results in the head being disassembled from the stick and the thin wire breaking so as to open the electrical conducting loop which changes the value of the identification number in the tag from the first code value to the second code value.

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.
