Small A-tent on Cash Hill, northwestern Eyre Peninsula, located close to edge of regolith and
possibly initiated beneath formerly more extensive spread of detritus.
The triangular gap whence came the slab remains identifiable. Several of the slabs bordering the gap
display a zig-zag pattern in plan due to the development of brittle tensional fractures (
Fig. 11.15b
).
Several more, similar, slabs remain in a tumbled mass below the triangular one. Above the gap left
by the slabs, several of the sheets of rock have slipped a few centimetres downslope. However, the
complex A-tent (X) developed some 20 m upslope from the major slippage is not associated with
any downslope movement (
Fig. 11.16).
The uplift of the A-tent slabs has, however, caused some
