Tamanos Mountain is a broad and gentle lava flow remant, extending N of Cowlitz Chimneys at about 2/3 of a mile NW of Owyhigh Lakes. Scrambling required to reach the summit.

Activity Notes

PEAK and ROUTE DESCRIPTION:

Tamanos Mountain (elevation  6790) is a rocky pyramid rising to the west above Owyhigh Lakes. It is a very popular scramble via its southeast ridge. This climb begins with a well worn hiking trail to a high saddle, then climbs through flowery subalpine meadows which turn to fall colors.  It is punctuated with a short bit of rock  to the summit. It offers a fairly easy ascent with just a little  rock scrambling, and spectacular views of the northeast corner of Mount Rainier National Park, including Little Tahoma Peak, Cowlitz Chimneys, and Governor’s Ridge.

Take the Owyhigh Lake trail for 3.5 miles from the White River road to Owyhigh Lake. From the lakes, ascend west and turn south to avoid cliffs and gain the SE ridge. Follow the bare crest north to the summit (climbers path and scrambling). Time up 4 hours, time down 3 hours. Return to cars by mid-later afternoon.

Both Cougar Rock or Ohanapecosh campgrounds are open,  but the latter is quite a bit closer to the climb.   This is where I plan to camp Friday (and Saturday) nights.
