A mainly ice-covered mountain, 2,865 metres (9,400 ft) high, which may be identified by the exposed horizontal bedding on the north face, located at the northeast end of Buckeye Table, Ohio Range.

The spur is named after the Canterbury Museum, Christchurch, N.Z., home of the National Antarctic Exhibition, Research and Reference Center.

Geologists Jane Newman and Margaret Bradshaw of the Canterbury Museum worked on this ridge during the 1984–85 field season.

The name alludes to the display of fossil wood found here and was suggested by William E. Long, geologist with the Ohio State University expedition who worked in these mountains in the 1960–61 and 1961–62 austral summers.

Resistant sandstone strata predominate in the lower half of the slope of the ridge, forming a series of partly ice-covered terraces separated by scarps.

The descriptive name was suggested by geologists of the Ohio State University expedition who worked in these mountains in the 1960–61 and 1961–62 seasons.
