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. Both smaller mountains, which remain unnamed, look miniscule compared to the mountain that is larger than it. If the Murderhorn is 20,000 feet high, then the mountain that precedes it would be around 11,000 feet.
