The Murderhorn

The Murderhorn is the highest mountain in Springfield that Homer climbed to promote the Powersauce bar.

Geographical formation
According to Bart, The Murderhorn is 20,000 feet (6144m) high. There are two smaller Mountains next to it meaning that there is/was possibly underground volcanic activity pushing the Mountains up.

Failed

 * Grampa - Apparently fell of the top of the Mountain.
 * C.W. McAllister - Grampa tried to eat him after he ran out of food. Froze to death.
 * Two Sherpas who were guiding Homer to the top (got fired).

Accomplished

 * Homer Simpson - destroyed the last peak making the second last peak the top.

Behind the Laughter
The Murderhorn is a possible parody of The Matterhorn. A Mountain on the Pennine Alps Between Switzerland and Italy.
