Mount Erebus has several named features on its slopes, including a number of rock formations.{{sfn|Ross Island USGS}}
Features around the summit of the mountain include:

===Helo Cliffs===
{{coord|-77.503455|167.116913}}. 
Prominent cliffs at about {{convert|3525|m}} high on the north rim of the summit caldera of Mount Erebus. The name derives from a nearby United States Coast Guard (USCG) HH-52A helicopter (CG 1404) which lost power and crashed while enroute from McMurdo Station to Cape Bird, Jan. 9, 1971. The four crew and passengers were not injured, but the helicopter was abandoned because of its location.{{sfn|Helo Cliffs USGS}}

===Seismic Bluff===
{{coord|-77.531538|167.079644}}
Steep bluff at about  {{convert|3470|m}} high on the southwest rim of the summit caldera of Mount Erebus.
So named after a seismic station nearby.{{sfn|Seismic Bluff USGS}}

===Tower Ridge===
{{coord|-77.532647|167.112645}}. 
A ridge at about {{convert|3540|m}} high that descends the southwest slope of the summit crater of Mount Erebus. So named because the ridge is defined by a series of fumarolic ice towers.{{sfn|Tower Ridge USGS}}

===Camp Slope===
{{coord|-77.528236|167.146427}}. 
A concave slope, about {{convert|3650|m}} high, just south of Crystal Slope on the west side of the summit cone of Mount Erebus. The feature is the site of a slump which has occurred off the crater rim. It is also a former camp site used by summit parties. A small hut is located on the upper part of the slope.{{sfn|Camp Slope USGS}}

===Robot Gully===
{{coord|-77.52682|167.145742}}. 
A gully at about {{convert|3675|m}} high on the northwest side of the summit crater of Mount Erebus. The feature was used as the access route from a NASA robot called Dante that was carried to the crater rim, Jan. 1, 1993.{{sfn|Robot Gully USGS}}

===Crystal Slope===
{{coord|-77.52563|167.150153}}. 
A western slope, {{convert|3700|m}} high, between Camp Slope and Robot Gully, leading down from the summit crater rim of Mount Erebus. So named because the slope includes a talus of large anorthoclase feldspar crystals.{{sfn|Crystal Slope USGS}}

===Nausea Knob===
{{coord|-77.521068|167.146857}}
A prominent outcropping of jumbled rocks,  {{convert|3633|m}} high, formed as a lava flow on the northwest upper slope of the active cone of Mount Erebus. 
The feature is near a camp site used mainly in the 1970s by teams working at the summit of the volcano. 
So named because many working at the camp suffered from nausea due to high elevation mountain sickness.{{sfn|Nausea Knob USGS}}
