This unit consists of 1 or 2 flow sheets, has colonnade- > 33 style polygonal jointing (À 1 m) and, at the base, inclined pipe vesicles occur. The lower Sandy Cove 10-20 m locally (e.g., Morden, Margaretsville) contains felsic material (ca. 65-74 wt. % 66°30'W SiO2 ) in the form of dykes, amoeboid masses and spectacular segregation pipes (3-60 ^Fnme 2 cm; 10-15/m ) that are sometimes cored by agate and crystalline silica.

One result of this work is the first geological map of this unit over the Geological Setting length of the North Mountain (Kontak, 2005, 2006), which provides a basis for assessment of the Numerous, early Mesozoic continental tholeiitic area’s resources.

Box 1199 Westport, Nova Scotia, B0V 1H0 Phone (902) 839-2995 Fax (902) 839-2075 [email protected] January 18, 2005 Dear Panel, We are seriously concerned and strongly opposed to the establishment of a Quarry at White’s Cove, Digby County, Nova Scotia. Our concerns are not only from a Tourism perspective, but also environmental issues as well as the commercial fishing point of view. It is our understanding that this Quarry will be in operation up to 50 years. If this were so, I can guarantee that the Bay of Fundy a once, flourishing feeding area for all marine life, will be nothing but a water wasteland, used for nothing more than the transport of goods, given the disruption to its marine life. Many species of whales inhabit the Bay. Resident species include the rarest of all whales in the world, the North Atlantic Right Whales, Humpback Whales, Fin Whales, Minke whales, Atlantic White Sided Dolphins, Atlantic White Beaked Dolphins and Harbor porpoise. The Bay of Fundy is so rich in nutrients that other species have visited the Bay following their prey such as Orcas, Pilot whales, Sperm Whales, Blue Whales, Beluga Whales and Common Dolphins. ( Our research division has collected data on these whales since 1984 and have these species documented by location, date, time, photographs etc. and it is available should you wish more information about the cetaceans that occupy the Bay of Fundy. Our data is also submitted to other research organizations who conduct studies in the Bay.

There has been a decline of the fishery, challenges in the fish processing sector, lack of economic growth, aging population and deteriorating service infrastructure. These circumstances have been complicated by two general population trends: increasing migration to urban areas and a low birth rate. Rural areas are now hard-pressed to retain youth and rejuvenate stagnating economies. Digby Neck/Islands in most respects faces these same challenges. A socio-economic profile of Digby Neck/Islands follows.
