CRATER HEIGHTS, THE GAP AND OBSERVATION HILL AS 

 VIEWED FROM THE OLD "DISCOVERY" HUT. 



The catenary curve of the Gap, due to glaciation, is well shown. In the foreground 

 is the icy slope which ended (abruptly on the right) in open water.

MOUNT EREBUS FROM THE OLD "DISCOVERY' 1 HUT. 



The steam cloud is blowing to the south-east against the prevailing surface winds. 

 The small craters of Cape Armitage are shown on the left as stumps of lava. 

 A series of false moraines crosses the picture (due to rock fall). In the fore- 

 ground are the " tesselations " due to soil-creep.
