Ascent Trip Report

Looking at Tamanos Mountain from the nearby Owyhigh Lakes trail, it’s hard to absorb its interesting topography, but a short trek to the east towards Governor’s Ridge allows you to see expansive meadows on Tamanos’ southern half, and steep, rocky, almost barren slopes on the north. The transition is abrupt, as if Tamanos possessed a Jekyll and Hyde personality (John Morrow's photo on the Tamanos home page shows this feature).
A quarter mile south of the Lakes, an inviting climber’s path departs the Owyhigh Lakes trail and heads up Tamanos Mountain through delightful meadows. My friend and fellow peakbagger, Vic Hanson, and I ascended on the easily distinguishable climber path as it meandered its way up to a grassy saddle, then ascended a steeper grassy ridge towards a sub-peak where the rocky transition begins. At this point we no longer had an easy path to follow, but the scramble route across the steep rocky ridge line towards the summit is obvious. We favored the western side frequently when the jumbled ridge line became difficult to traverse. The summit is relatively small, just big enough for two or three people to eat lunch and enjoy the breathtaking views. This day we could see the Sunrise area, Goat Island Mountain, Little Tahoma, Banshee Peak, and the Cowlitz Chimneys. A cold wind kept our lunch break short and after briefly considering possible routes down the steep and imposing terrain to the north, we descended the way we came.
Once on the trail, we made a short side trip to explore a route up a gully leading to the base of Governors Ridge. We couldn't see this route from the trail but climbing Tamanos allowed us to see it clearly.
