This is not Egg-zillaration. The Egg-zillaration is on the left skyline of the formation, starting out of the chimney/gully & passes 5 bolts to the anchors.
The route going up the center of the picture is an old chossy toprope we called "walking On Eggshells". I have no idea who bolted it but is badly flawed because the bolts do not follow the line of climbing, which is to the left of the bolts.
JWong, The route you have referred to is, as JJ Brunner indicated, a 5.11a. The crux lies just above the climber in the photo. A popular sequence goes left at this point, and back to a 4th bolt, above the bulge. Once past the bulge there are 4 more bolts leading to a bolted anchor, not equipped for lowering. Hope that beta helps you.
ps. Egg-zillaration (5.11a) - 5 bolts, stems up the chimney/gulley on the RIGHT skyline of The Egg, with Walking on Eggshells (rumored to have been bolted by Graham Doe) following the sun/shadow line up the NE side.
