When impacted by an external force, the marker post flexes.

A marker post for identifying a location comprising:
- a base having a bottom portion fixed to a surface and an upper portion having a means for connection;
- flexing means having a first internal diameter and a first external diameter, said flexing means further having a bottom end axially coupled to said means for connection and responsive to an external force for deflecting a predetermined amount;
- a pipe axially coupled to a top end of said flexing means for receiving said external force, said pipe having a second internal diameter smaller than said first external diameter, said pipe being axially forced over said upper end of said flexing means.
A marker post comprising:
- a detachable base means having a taper at a lower end for installation in the ground, and a thread means at an upper end;
- a stud means having a mating thread at one end being fastened to said thread means for securing said stud means to said upper end of said base, said stud means having a first external diameter at an opposite end;
- a spring means having a first internal diameter and a second external diameter, wherein said first internal diameter is smaller than said first external diameter of said stud means, and wherein a first end of said spring means is axially forced over said first external diameter of said stud means;
