A Geosite Day on the Bay
(L-R) Kevin Noseworthy, Joan Oxford and Tony Oxford at the base of North Arm HillThe day began on the beach and adjacent wharf at Cox's Cove
on the way to Little McIvers. The fishing outport is one of a number of small seasonal communities where inshore fishermen from Humber and Middle Arms set up operations for the summer.
Little McIvers on the south side of North Arm near North Arm PointJust across the arm looms North Arm Massif, the only one of four Bay of Islands Ophiolites which rises directly out of the ocean.
Just to the west is Back Cove, location of the IATNL North Arm Traverse base camp.
Unlike North Arm Hill, the mountains around lower Liverpool Brook are part of the Blow Me Down Brook Formation, just east and west of the Blow Me Down Ophiolite on the south side of the Bay of Islands.
A little further to the west, the landscape changes to the Middle Ordovician Crabb Brook Group, a mix of pebble to boulder breccia, red, green and gray shale, and calcareous sandstone and siltstone.
The pebble beach extends approximately 5kms (3 miles) and connects the seasonal outports of Crabbs Beach and Lower Crabbs Brook.

Seasonal outport on the northeastern end of Pearl (Big) IslandPearl Island provides a spectacular vantage point to view the Gregory Mountains, composed largely of gabbro from the earth's oceanic crust.

with a snug little outport tucked away behind headland and islet.

while Tony and Joan were up front steering for home!
The last stop before port was Green Island (aka Eagle Island), a small low island with a colorful mix of red sandstone and gray shale topped with lush green grass
almost as colorful as the orange and green Bay of Islands dories lined up safely on their slips!
