The first known trip to the top of Roraima was made in 1884 by Im Thurn.
Thurn made lectures about his expedition in London. One of these lectures
was attended by Sir Arthur Conan Doyle, who was so impressed by what he'd
heard that he wrote a novel based on Roraima, which he entitled "The Lost
World", first published in 1912.
Sir Walter Raleigh published a book entitled
"The Discoverie of the Large and Rich Territorie
of Guyana" in 1596, in which he mentions a "crystal mountain" now thought to
be Roraima.
I hope you enjoy my photos of Roraima Tepui in Venezuela.
