Originally referred to the State Mine entry but now locally refers to the steep section of road on State Mine Gully Road, 1.8km north of the railway workshops. The gully in which the State Mine was located was locally known by a number of names - Steak Knife Gully, Permafrost Gully, Dobbs Drift and The Drift. Dobbs Drift is located 1.5km north of State Mine Museum referred to in the entry under the State Mine. A drift is an incline access into a mine, i.e. not vertical or horizontal. The mine entrance, built in 1948, was named after John Phillip (Jack) Dobbs who was the State Mine Miners Federation Lodge Secretary.
