close to the valley's mouth. At this point, Malvern Street becomes Duke Street, which intersects with the city's main commercial street, George Street at the valley's mouth. The suburb's only retail outlet, a dairy and grocery store, is located at the junction of Duke Street and George Street. A series of walkways runs through Woodhaugh Gardens and along the banks of the Leith. One of these follows the course of the stream from the northern end of Woodhaugh Gardens to connect with the Ross Creek tracks, passing as it does a major weir (the Boulder Trap) which was put in to prevent a repeat of the major flooding of the Leith in the early 20th century. The walkway also passes the remains of the former Woodhaugh Quarry, which operated until 1949. The sides of the Leith Valley are notably steep, especially in the area around the start of Rockside Road (also the location of the confluence of the Ross Creek and Leith). At this point, steep cliffs flank the valley, and nearby the Ross Creek passes through a narrow canyon. In the lower reaches of the valley, the valley's walls are still steep, though not vertical. The Dunedin Northern Motorway skirts the northern edge as it passes by the suburb of Dalmore, and along the southern edge of the valley, a walking track rises sharply, connecting Woodhaugh with Prospect Park, New Zealand. This track, the Bullock track, was originally part of a trail used by farmers taking cattle from the farms of North East Valley to abattoirs in Burnside, Otago.
