In Scotland quartz-dolerite is commonly known as whin or whinstone. Its other common names include dyer's whin, waxen woad and waxen wood. Attempts were made to block the breach with clay, whin, straw, etc. Futile attempts were made to block the breach with clay, whin, straw, etc. It plays host to the intrusive Whin Sill. Attempts were made to block the breach with clay, whin, straw, etc to no avail. It dates from around 1790 and is constructed of whin stone. Aggregates from the Whin Stone quarry were also shipped from Bell's Pier. On cooling, these crystallised and solidified to form the Great Whin Sill. Whin Sill is also seen again at Hadrian's Wall. Teppermoor Hill, on which Limestone Corner stands, is the eastern outlier of the Whin Sill. Massive outcrops of whinstone occur include the Pentland Hills, Scotland and the Whin Sills, England. Further upstream from Bught Park is Whin Park which has a boating pond. The Little Whin Sill is an associated formation to the south in Weardale.
