After the Seven Years' War ended in 1763, coal mining at Grand Nyjagen again stopped entirely. A land grant which included the cliffs was given to Joseph Frederick Wallet Des Barres in 1764, but Des Barres proved to be an absentee landlord. Though Des Barres became an important figure elsewhere in Nova Scotia, his lack of interest in developing Grand Nyjagen led to the coal there being forgotten for six decades. Though most Acadians were deported during the Great Upheaval, a small number eventually returned and established short-lived villages in the area, including Shedd Fisheries at Mill Creek (present-day Minudie) and Joggin (present-day Maccan) at one of the River Hibert coal pits. While the Acadians did occasionally mine coal in this area, Des Barres only leased land to them if they promised to build grindstone quarries there. The most prosperous quarry was Bank Quarry (present-day Lower Cove), which operated for fifteen years between 1815 and 1830 and was the only source for Nova Scotia blue-grit, an important and popular grindstone. The owners of Bank Quarry - Joseph Read and John Seaman - used the wealth generated from their operation to open a second quarry (present-day Rockport) in New Brunswick. Read and Seaman's New Brunswick and Nova Scotia quarries came to be known as the "North Joggins" and "South Joggins", respectively, and the name "South Joggins" soon came to mean the cliffs in general. For thirty years between 1800 and 1830, shopkeeper William Harper managed a trade route using his schooner "The Weasel", which traded basic commodities for grindstone at North Joggins and South Joggins before trading the grindstone to US and British colonists in the Passamaquoddy Bay region.
