Field observations made during the 2004-2005 field season, using such features as sill steps, sill bridges, orientated phenocrysts and asymmetric structures to determine regional magma flow directions in the Theron Mountains. A full photographic record of the cliffs was made at a transit of 1km out from the cliffs.
