Cache of the Month December 2020 – The Sugarloaf Earthcache

Hallett Cove is one of South Australia’s foremost natural science treasures. Concepts of superposition of strata, unconformities, folding and faulting of sedimentary rocks are clearly displayed. In 1877 Professor Ralph Tate discovered evidence of ancient glaciation in the form of polished and striated rock surfaces on the cliff tops and the site has attracted scientific attention ever since.
