1. SE Ridge (1949) Ian Kay, H Genschorek. Class 3-4. From Pandareus-Ionia col, follow lower and slabby part of SE corner or bypass it on the south. Continue over loose rock to summit. Takes 1 hours from the col.
2. West Buttress (1969) Dick Culbert, Alice Culbert. Class 4. Drop down from Serratus-Ionia col to its west side or backtrack from the Red Tit Hut. Traverse south on a major ramp on the west side of the divide to reach the West Buttress. Five leads, mainly pleasant. Takes 2 1/2 hours up. A tower on the buttress provides a presumably spurious diversion- a lead of class 4 from the uphill notch.
3. North side (1961) Jack Bryan, Jim Craig, Martin Kafer, Ester Kafer. Class 3-4. A convoluted route. It begins from the glacier south of Serratus at the lowest rock descending from the main divide north of Ionia. This is termed a NE rib. Follow its crest to a gendarme and 100m beyond it, traverse a wide ledge on the rib's east face then return to the rib's crest up a class 4 wall. Climb a second (last?) gendarme on ridge (rib or divide?) over slabs and blocks, then west face. Continue up N divide of Ionia (presumably heading south) on fairly good rock. Takes 4 hours from base. (If someone ever repeats this, please provide some clarification.)
