On QI broadcast recently in Australia there was discussion of the outline of a elephant drawn as a contour
on an old topo map.
"In 1924 a group of young Army officers were surveying an inaccessible part of Africa's Gold Coast. At the end of a hard day's work under the tropical sun, a single hill remained. The men decided that, using a little imagination, the small area could be artificially filled in. They drew around a picture in a magazine,
creating contours in the form of an elephant. Their improvisation was not detected and the elephant can be seen at least into the 1960s." - Lizzie , program researcher
Has anyone found similar instances of easter eggs on O maps, or is even willing to confess to creating their own?
The reason that a program like this can take 4 years to get to Australia is whole different subject for discussion.
