“The ‘Big Tits’”
Which is the English translation of ‘Grand Tetons’
Key Facts (via GROK)
• Size: Approximately 310,000 acres (about 485 square miles / 1,300 km²).
• Established: 1929 (protecting the main peaks); expanded in 1950 to include most of the former Jackson Hole National Monument.
• Highest point: Grand Teton at 13,775 feet (4,199 m). It rises more than 7,000 feet above the valley floor of Jackson Hole, creating one of the most abrupt and photogenic mountain fronts in the Rockies.
• Range: The Teton Range runs roughly 40 miles north-south and 7–9 miles wide. Other notable peaks include Mount Owen, Middle Teton, South Teton, Teewinot, and Mount Moran. 
The name “Teton” comes from French fur trappers who called the three prominent peaks Les Trois Tétons (“the three breasts”). Local Shoshone people referred to the range with terms related to many pinnacles.
“The Oregon Trail”
This is behind a rest area on I-86 (the 86 for you Californians), near Coldwater ID.
The Oregon and California trails split at the ‘Hudspeth Cutoff’, approximately 10 miles (or a day via wagon) further.
