Geocache Description:

Mahoneys Barrier Island

Other viewing points are N45° 42.292' W61° 54.031' and N45° 42.178' W61° 54.209'

Mahoneys Beach is situated at the mouth of Antigonish Harbour along the Sunrise Trail, just 11 KM out of Antigonish on Route 337. The western end of Mahoneys Beach was breached in late December 2004 creating a new inlet to complete the formation of the barrier island as it split from Mahoney Beach.

The new inlet is similar in morphology to the main inlet. It is asymmetrical, which is consistent with obliquely approaching waves of the longshore current. The flood tidal delta is well developed, but the tidal current is relatively strong, resulting in a deep, ebb-dominated narrow channel with marginal bars.

Barrier islands are coastal land forms and a type of dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen.

They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend uninterrupted for over a hundred kilometres, excepting the tidal inlets that separate the islands.

The length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends, and basement controls. The amount of vegetation on the barrier has a large impact on the height and evolution of the island.
