North Pacific humpback whale showing extensive scarring, almost certainly from a boat propeller, on dorsal ridge. This female North Pacific humpback whale was first seen with the depicted lacerations near the island of Maui in the Hawaiian Islands in the mid-90s, and is the original humpback to bear the name 'Blade Runner'. This female has apparently recovered, as evidenced the calf she was observed nurturing. A South Pacific humpback whale endured a similar injury in Sydney Australia in 2001, and bears a remarkably similar scar pattern to the above-pictured whale.
Species: Humpback whale, Megaptera novaeangliae

Arc de Triomphe. The Arc de Triomphe (Arc de Triomphe de l'Etoile) is one of the most famous monuments in Paris. It stands in the centre of the Place Charles de Gaulle (originally named Place de l'Etoile), at the western end of the Champs-Elysees. The Arc de Triomphe (in English: "Triumphal Arch") honors those who fought and died for France in the French Revolutionary and the Napoleonic Wars, with the names of all French victories and generals inscribed on its inner and outer surfaces. Beneath its vault lies the Tomb of the Unknown Soldier from World War I. The monument was designed by Jean Chalgrin in 1806, and its iconographic program pitted heroically nude French youths against bearded Germanic warriors in chain mail. It set the tone for public monuments, with triumphant patriotic messages. The monument stands 50 metres (164 ft) in height, 45 m (148 ft) wide and 22 m (72 ft) deep.

The canyon is approximately 10,000 years old, 20 miles long, 1000 ft deep, and 2500 ft wide. Its yellow, orange and red-colored walls are due to oxidation of the various iron compounds in the soil, and to a lesser degree, sulfur content.
