Mt. Jefferson is the second highest mountain in Oregon, and a notch or two up in difficulty and commitment than the South side of Hood. The Milk Creek Glacier is seldom climbed, but offers the most direct route to the summit from the trailhead. Try this route only when snow covered - it's a steep scree slog later in the season. While one day ascents are possible for the fit climber, long days and unexpected bivies can be common. Be very cautious of rockfall on this route!! Do not attempt it if you see significant rockfall hazard. Be sure and check with the Detroit Lake USFS office for any permits needed for the Pamelia Lake trailhead - it's a heavily used area and advance permits may be needed.
