ABSTRACT:
A marker comprises an elastic visible element connected to a base. The visible element extends upwardly from the base so that it may be seen from a distance. The visible element is elastically deformable to allow a machine, such as a mower, to pass over the marker without causing damage. The marker may be illuminated to be visible at night.
