Zebulon Pike
In early November 1806, Pike and his team sighted and tried to climb to the summit of the peak later named after him (Pikes Peak). They made it as far as Mt. Rosa, located southeast of Pikes Peak, before giving up the ascent in waist-deep snow. They had already gone almost two days without food.
The Ascent of Rum Doodle
A small mountain in the Masson Range in Antarctica, near Mawson Station, bears the official name Rumdoodle Peak inspired by this book. A mountainous point in Aoraki/Mount Cook National Park in New Zealand is known as Rumdoodle. The northeast ridge of Pikes Peak, in Colorado, has been unofficially nicknamed Rumdoodle Ridge by local climbers. There is a hidden couloir in the Vanoise National Park, also unofficially known as the Rum Doodle, and named by one of the first to discover and ski down it, Will Eaton. So-called as it took a long time to find the entrance, and skiing down it wasn't without complications.
