The 1400 ft high west face has got to be one of Oregon's biggest walls. Very impressive and remote. See this page for info on the "Matterhorn Pit". The author asserts that it's unexplored with no one to claim a "first descent", but I'm not so sure since cavers are very secretive. I'm also curious about the Sacajawea-Matterhorn ridge. You should add a route description to the mountain page.
