Sentinel Rock Climbing

Easiest way to the summit is original route,1938. It's 5.7+R, possibly X, a few short exposed moves to go up around the corner where it seems you are stuck and things are improbable. In recent years someone added bolts on the face just left of where you would traditionally turn the corner to the right. I was told by CP they were good climbers and assumed rock fall removed the original route. It did not. Another party, unsure of where the original route goes, climbed the crack to the left of the bolts, placing trad gear in the crack, rating it 5.9ish. This is not 5th class. Climbers in the 1930's were hard men. Re "Peak has probably seen less than 10 ascents" - I've done it several from both sides (the other being from the top of the water fall at Birch Creek). Re "maybe only 10 parties have stood on top, " based on my explorations of other peaks and canyons nearby, it's probable there have been ascents unmentioned in the years before the internet and Facebook, by climbers just "climbing" for the sake of being out there. This is based on my finding evidence of previous (1960's?) parties in places the summit of the Sentinel is one of the few places they could have gotten there.
