Its always a good idea to grab a metal detector and check trees before cutting into them along the former battlefields of the Eastern Front as they sometimes pick up the strangest objects.
As chronicled by a post on Ghosts of the Eastern Front, a group that follows the hobby of relic hunting along the old WWII battlefields throughout Eastern Europe, apparently a full-sized tree was recently found grown around what looks to be a spike bayonet from a Russian M91 Mosin-Nagant rifle. These pig stickers are almost two feet long which means the tree itself has been around for a while as only the socket is still hanging out.
While we can’t tell you exactly where the tree in the above images is from, these photos below taken a couple years ago outside of St. Petersburg around the Nevsky Pyatachok area attest to the fact that its not an uncommon occurrence.
In Russia it seems, guns really do grow on trees. As well as grenades, helmets and machine guns.
