Mount Jefferson, Stratovolcano in Cascade Range, Oregon, US
Description
Mount Jefferson rises to an elevation of 10,497 feet, making it the second highest mountain peak in Oregon's Cascade Volcanic Arc formation.
History
The first documented climb to the summit occurred in 1888 by mountaineers R. L. Farmer and E. C. Cross, marking the beginning of recorded ascents.
Culture
The mountain received its name from the Lewis and Clark Expedition in 1806 as a tribute to President Thomas Jefferson of the United States.
Practical
Access requires hiking from trailheads on the western slopes, with most routes involving several hours of walking through forested terrain before reaching alpine zones. Conditions vary throughout the year, and snow often lingers into summer months on higher elevations.

At least 35 smaller vents scatter across the terrain within 15 kilometers of the main cone, revealing a long history of volcanic activity. These secondary openings contributed material over thousands of years, shaping the landscape visible today.
