Giant Sequoias (Sequoiadendron giganteum) are the world's largest trees; and largest living thing by volume. The trees grow to an average height of 50–85 meters and 6–8 meters in diameter. Record trees have been measured at 94.8 meters in height.
They are also among the oldest living things on Earth. The oldest known Giant Sequoia based on ring count is 3,500 years old. Sequoia bark is fibrous, furrowed, and may be 90 cm thick at the base of the columnar trunk. It provides significant fire and insect protection for the trees.
Here are two examples to show the large size of the tree. Location: Crescent Meadow Road, Sequoia National Park, California, USA
near Giant Forest Museum Date: 2018 May
(Location and date are the same for both examples.)
1) Tunnel Log
Visitors to Sequoia National Park can drive through a fallen "Tunnel Log" located along Crescent Meadow Road near Giant Forest Museum of the park.
The fallen log came into being after a Giant Sequoia fell across the road as a result of natural causes on December 4, 1937. The following summer, a tunnel was cut through the log as a visitor attraction.
When it fell, the tree stood at 83.8 meters feet high and 6.4 meters in diameter at the base. Its age when it fell has not been determined, but probably exceeded 2,000 years.
The tunnel, which remains in use today, is 5.2 meters wide by 2.4 meters high.
In the 3 pics below, I am driving a hired Toyota Camry through the log.
2) Auto Log
The Auto Log was once another Giant Sequoia. It fell down in 1917. Because it landed right next to Crescent Meadow Road in Sequoia National Park, park authorities decided to turn it into a visitor attraction. A kind of parking space was gouged along the upturned side of the tree trunk, and visitors were encouraged to drive their cars off the road and onto the trunk as a way to convey the size of the big Giant Sequoia.
Nearly a century of rot, and countless thousands of cars, have been too much even for a Giant Sequoia, and the battered trunk is now off-limits to vehicles. But visitors can still walk the length of the former log roadway.
Sign on toilet wall:
Do not drink
Location: Toilet in Bright Angel Lodge, Grand Canyon Village (South Rim), Arizona, USA Date: 2018 June Reason: No idea why such a sign is necessary. Perhaps it implies that in other toilets where reclaimed water is not used, then one can drink it from the bowl ???
Species: Highland Copperhead (Austrelaps ramsayi)
Location: Close to the summit of Mt Scabby, ACT, Australia
Date: 2018 January
Usually snakes would move out of the way when they heard people approaching.
Not this one ! This one was not afraid of us, not budging from its ground.
Glad we saw it first and didn't step on it !
It also liked to flick its tongue in and out.
