ABSTRACT:
A device for marking a location. The device coming in two separate pieces, namely a ground stake and a marking post. The ground stake configured for insertion into a ground surface. The marking post configured for attachment to the ground stake. The post is preferably removable from the stake so that when livestock are present, if they uproot or displace the marking post portion of the device, the ground stake remains in the ground still marking the location. If a survey crew or other individual is at the marking location after the post has been removed, they can replace the post (or insert a replacement post) to return the device to its full functionality.
