L'Arbre du Ténéré, known in English as the Tree of Ténéré, was a solitary acacia, of either Acacia raddiana or Acacia tortilus, that was once considered the most isolated tree on Earth — the only one within more than 400 km. It was a landmark on caravan routes through the Ténéré region of the Sahara in northeast Niger — so well known that it is the only tree to be shown on a map at a scale of 1:4,000,000. It was located at approximately 17°45′00″N 10°04′00″E / 17.75, 10.066667.
This tree was struck not once but twice by vehicles and has been moved elsewhere, replaced with a metal sculpture. Follow the link to see pictures of the terrain and marvel that you and yours are allowed near machinery.
