What is "cronk-ny-mona"

Cronk-ny-Mona, a steep hill topping-out to a sweeping left hand bend located after Hillberry corner on the TT course, leads from agricultural farmland and passes through sympathetically-landscaped modern residential developments on either side, continuing the traditional rural theme and demarking the outer-margins of Douglas town. The hill interrupts the descent from Snaefell Mountain, which resumes at the next TT vantage point, the right turn at Signpost Corner, starting the run down through the outskirts of Douglas to the finish line at TT Grandstand.
