8.6 Horlick Mountains

Work continued in 1960-1963 in the Ohio Range (formerly called the Central Range of the Horlick Mountains) to procure coal for accurate analysis. Samples of outcrop coal and one excellent sample of coal from an adit opened in one bed were collected. Coal samples were taken in 1959 by John J. Mulligan (31) at Mount Gran in the vicinity of Frank Debenham and McKenzie Taylor s old Mount Suess locality. The following season Mulligan (32) sampled coal farther inland in the Willett Range. Brown and Taylor (6) published an analytic report on coal from the Theron Mountains in 1961.

The Antarctic coal samples are reportedly of Permian age and were collected in 1957 as part of the Antarctic exploration program of the Ohio State University Institute of Polar Studies. The bulk of the samples are from two localities shown in Figure 1 (1) the Terrace Ridge in the Ohio Range of the Horlick Mountains, and (2) Mount Gran in the Granite Harbour area of South Victoria Land. In each instance the coals were sampled from each of the accessible coal seams in the stratigraphic sequence exposed. Thus, these sam-... 

Eventually the tractor train arrived at Station 414 at the foot of the Horlick Mountains and was delayed there by lack of fuel. The resupply plane from Byrd Station had to turn back several times because of bad weather, problems with radio transmissions, and mechanical problems. While the group waited for several days for the plane. Bill Long and three of his companions decided to climb Ml Glossopteris which is one of the highest mountains in that part of Antarctica at 2,867 m above sea level.

The Shackleton Glacier (84°35 S, 176°20 W) marks the southern limit of the central Transantarctic Mountains as defined in Fig. 3.1. It is also the northern limit of the Queen Maud Mountains which extend along the strike of the Transantarctic Mountains to the Reedy Glacier and to the Wisconsin Range of the Horlick Mountains located at about 86°S and 125°W.
