From the campsites (6245' for the lower campsites), head North up the west side of the Sulphide Glacier up rolling steps. Around 7600', the route flatten out, and your path with be more NNE, towards the summit pyramid. At the base of the summit pyramid, the standard ascent is up the 3rd class gullies to the summit, however there is also the Southeast ridge, which is mostly 4th class with some low 5th class sections. On the descent, you can down climb, or there are usually webbing anchors with rap rings.
Ice axe, crampons (if in colder weather), picket, crevasse gear, etc.
