A device for flagging an object buried in the snow includes a flag housed in a pouch, and held within the pouch by a closure mechanism such as a snap closure or a hook-and-loop closure. The flag is attached to a tether by means of an encircling element that passes around the closure mechanism (for example the encircling element could comprise a loop on the pouch end of the tether). As the encircling element is tugged on sharply, it forces the closure mechanism open, which allows the flag to exit the pouch, unfurling as it goes. The flag is attached via the tether to the object to be flagged, such as a ski, while the pouch remains fastened to a base object such as a ski boot. The system may also be used to locate avalanche victims, in which case the flag is attached to the person, thus providing a visual clue to the location of the victim buried below the surface of the avalanche.
