Abstract
A location marking device includes a hollow body adapted to function as a spike or stake for insertion into the ground, and a roll of a narrow strip of sheet material disposed within the hollow body and adapted to be withdrawn axially therefrom through one open end. Withdrawal of the coiled strip by grasping and pulling the inner end thereof forms a narrow, self-supporting conical spiral. The device provides a safe, convenient, economical and very functional means of marking the location of underground utility lines and the like.
