Toura July 19-1912. Friday
Left Dorchester at 8.30 A.M. and arrived at
Toura at 11.30. Stopping at the Stanley House.
It began to rain at Dorchester and here at Toura
it rains hard all day. Bound to the Hotel.
Late in the afternoon after the rain walked
through Victoria Park. A small stream comes rushing
down the hill and has cut in the Oriopecock, a drain
a sharp V shaped valley. It's a romantic cliff
turned into a pretty park.
The Oropecock stands at a high angle and consists
apparently of sandstone and sandy shales all lacerated
by the mountain eroding forces.
Over the Oropecock very unconformable lies the
Triassic which also has a dip but it is very low
probably less than 10°. On entering the park we see
the Triassic almost at the level of the stream and
in less than ½ mile distant it rests on the Oropecock
at an elevation about 200 feet above the stream level.
The Triassic topography was therefore a rough one.
