Abstract: A device adapted to be at least partially inserted into an aggregation of material and retained therein. The device has an opening formed therethrough to receive a novel anchoring component. The device may be a marker which advantageously has a Miles Utility configuration, and which has the opening formed in a stake portion of the marker. The anchor has a bridge element which extends through the opening to hold a pair of legs in an opposed and upright position. The legs resiliently grasp the opposite sides of the marker to prevent the anchor from falling out or being bumped out of the opening. There is also disclosed a two-piece marker with the Miles Utility configuration for the post which is resiliently joined to a support to provide a universal hinge action to prevent the wings from being crumpled or permanently deformed to prevent or inhibit the post from returning to an upright position.
