Illusion- 5.10a/ Originally rated an old school 5.9, Illusion will work you even by 5.10 standards. This is a beautiful sustained line just to the left of the corner that forms the left side of the roof. Illusion consists of a single crack with a tough start past a loose chockstone. The crack starts to eat you up as it opens below a small roof move. Once you ascend this section, you move into a single fist sized crack that splits above. Take the left fork as it finally eases up towards the top. Move out left around loose blocks to a bolted station (2007). This pitch requires a double rope rappel which allows you to get a good look at the next route to the left, Twin Crack. (photos)
