The Elfas is a range of hills up to 409.6 m above sea level (NN) in the districts of Holzminden and Northeim in Lower Saxony (Germany). Its name is derived from the Lower Saxon word Fast, which means an area of upland that descends on two sides.
The Elfas is located in the middle of the Leine Uplands between the Hils to the north, the Homburg Forest to the west, the Hube to the east, the Amtsberge to the south-southwest and the Holzberg to the southwest. It lies not far southwest of Eschershausen and east of Stadtoldendorf; the town of Einbeck is about 12 km southeast of the Elfas. The B 64 federal highway runs past the Elfas to the north linking Eschershausen with Einbeck.
The rounded summits of the Elfas are covered by acidic soil beech forests.
The Elfas is mainly composed of sandstones from the Bunter sandstone period. As the result of a halokinetic process, which had already been concluded in the Palaeogene period, the Elfas fault block migrated in a north-easterly direction towards the Solling, whereby the mountain-building sandstone rode up over a layer of saliniferous rock of the Zechstein. In the course of this process, mainly older rock strata that had hitherto lain underneath, were overthrust. Out of the subsequent erosion processes today's scarpland emerged as the northern boundary of the Einbeck-Markoldendorf Basin.
