Abstract

These notes are intended as an incentive to future
study rather than as a complete record of the geology of
this interesting locality. They are the result of several
holidays spent on the island, and particularly of two
yachting trips undertaken recently. In many places the
record is meagre, as I was unable to land and examine
the rock formations in detail, but had to rely on observations
made while sailing along, often in somewhat
troubled waters. Still the description is complete
enough to be of value, especially as no previous record
has been made, with the exception of the late R. M.
Johnston’s description of the Fossil Cliffs in his Geology
of Tasmania. There is brief mention of a paper read by
him before the Royal Society on Riedle Bay, but unfortunately
it was not printed and his valuable observations
have been lost.
Maria Island is situated on the East Coast, almost
opposite to Spring Bay and Orford. The passage between
it and the mainland varies in width from three to eight
miles. In the narrowest part, off Long Point, is Lachlan
Island, a small diabase rock covered with sparse vegetation.
Maria Island is one of those curious "tied-islands" to be
found in Tasmania. The reason for their formation has
not yet been determined, though it is usual to ascribe
it to the sinking of the land, and, though not sufficient
data has been collected to dogmatics on the matter, there
is no reason to suppose that there have been any other
forces in operation.
