[...] The line of march, however, lay through the plain to the east of the Alwar hills, and missed most of the solid geology of this area. [...] Another very striking feature of the scenery is the absence of outstanding peaks among the Alwars and the level line of the summits of the ridges. [...] The level of the summits is greatest to the west of the Ajabgarh valley,1 about 1,100 feet above the plain, and falls steadily and gra- dually to the north and east in the same direction as does the level of the plain but with a steeper gradient, so that they approach each other ; thus in the Alwar-Gurgaon boundary ridge the difference between the two is about 400 feet as a rough average, decreasi [...] This lobate surface of contact is now cut across in section by the present surface of the land, resulting in the PreDelhi rocks ex- formation of a series of broad embayments in posed in bays. " which the scarps of the lowest Delhis over- look the alluvial plain occupied by the older rocks, the bays being separated from each other by narrow synclines representing the nipped-up portions of the fold
