Mt. Si is the most frequently climbed peak in Washington as far as I know. Even though it is only about 3000 or so feet, it rises up from North Bend with a pretty steep West face so it is pretty prominent and the interstate goes right around the South side. It's a typical looking forested foothill type mountain with a rocky summit at Haystack Basin. This is a bit washed out, not the best pic of Si that I have by any stretch.
