Since unc mentioned Jefferson, I'm throwing in some interesting related geography. Here's a nice pic of Mt. Jefferson in Oregon. Wiki:
Mount Jefferson is a stratovolcano in the Cascade Volcanic Arc, the Cascade Range and is the second-highest mountain in Oregon. Situated in the far northeastern corner of Linn County about 60 miles (97 km) east of Corvallis, Jefferson is in a rugged wilderness and is thus one of the hardest volcanoes to reach in the Cascades though USFS road 1044 does come within 4 miles (6.4 km) of the summit. Many people consider Jefferson's craggy, deeply glacially scarred appearance to be especially beautiful and photogenic. The peak has therefore frequently served as a backdrop for automobile and alcohol advertisements in the United States.
