This note indicates the furthest east point reached by the Geological Party of the
Byrd Antarctic Expedition. We are beyond or east of the 150th meridian and there-
fore in the name of Commander Richard Evelyn Byrd claim this as a part of the
Figure 5.16. From the summit of Supporting Party Mountain, Gould's party looked to the south and
east, where the mountains narrowed to a single cliff, disappearing from sight far to the east. A
broad glacier drained the front of this escarpment, appearing to head at its distant termination. In
fact, Leverett Glacier drops through a narrow cleft in the face of the Watson Escarpment, not vis-
ible from Supporting Party Mountain (see Fig. 5.6). In this image from Mount Webster, ten miles to
the southeast of Supporting Party Mountain, Evans Butte, the flat-topped outlier of the exhumed
erosion surface on Watson Escarpment, deflects cold, gravity-driven, katabatic winds into lenticular
clouds. Watson Escarpment, mantled in its own ground-hugging katabatic cloud, appears in the left
distance and peeks through the two saddles to the right of Evans Butte. Leverett Glacier flows from
left to right in the foreground of the image.
