There are several routes up Mt Erebus. The following are the routes I used. An ice axe should be carried into January.

From the Lake Wilson outlet make your way up the ridge to the northeast and on up to Point 1578 which is located by a large boulder field. Make your way across the boulders and climb up rocks to the right (south) of a massive bluff. At the top of the bluff it looked possible to sidle to the left (north) above the bluff and climb up to Mt Erebus but I sidles to the right (south) and climbed up through small bluffs via a series of ledges to eventually gain the ridge line at about 1860m From here, if theres not too much snow, you should be able to head along the ridge and up the south flank of Mt Erebus. The route down (which is also a way up) goes down the ridge to Point 1821 where you climb down its eastern side and circle around to the ridge line between 1821 and Peak 1829. Descend southwestwards here, down the true right of a small stream on rock, eventually into the head of the valley north of Mt Xenicus. Regain the ridge line above Lake Wilson and return to the outlet.
