Location	Toolern Vale - 837434. Former Shire of Gisborne. Ridge extending west from Gisborne - Melton Road, 6 km southwest from Gisborne.	TV3
Ownership	Gisborne - Melton Road.

Site Description	Murray Spur is a convex ridge capped by one of the early flows from Mount Gisborne that filled a small valley cut into Ordovician sediments. The flow now forms a distinctive rounded ridge on the margins of the Gisborne Highlands.
Significance	Local. The site is an example of one of the earlier Mount Gisborne flows and a small scale example of topographic inversion.
Management	Class 3. Continuation as rural land or small farm subdivision would retain the significant form of the site.
