The Bishop is primarily what you are discussing here : http://mountainproject.com/v/colorado/south_platte/cathedral_spires_area/105745286
It is an important rock in regards to technical climbing history, in particular Colorado climbing history. Ellingwood Chimney is a classic test piece.
"Bishop Rock" is what the 8,260' (interpolation) closed contour summit is "named". It is a ranked peak with >300' of prominence.
Great peak, though!
changed the site accordingly - wasn't sure from the beginning if I got the name right but could not find more info on the web
