In geomorphology and geology, a peneplain is a low-relief plain formed by protracted erosion. This is the definition in the broadest of terms, albeit with frequency the usage of peneplain is meant to imply the representation of a near-final (or penultimate) stage of fluvial erosion during times of extended tectonic stability.

Pietra di Bismantova in the Apennines, Italy. An inselberg or monadnock (/ m ə ˈ n æ d n ɒ k / mə-NAD-nok) is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain.
The Perris Plain, an uplifted peneplain, is drained primarily in the San Jacinto Basin, the San Jacinto River watershed flowing into Lake Elsinore, that is dotted by monadnocks and by several other ranges of mountains and hills.
Mount Monadnock, or Grand Monadnock, is a mountain in the town of Jaffrey, New Hampshire. [3] It is the most prominent mountain peak in southern New Hampshire and is the highest point in Cheshire County.
A peneplain with the occasional moderately high monadnocks left behind during the peneplanation of the rest of the surface. The erosion of the region must have been far advanced in prehistoric times, even practically completed, because the even peneplain surface is overlapped by fossiliferous marine strata from an early geological date ...
That landscape of low relief is called a peneplain and may contain residual heights standing out from the general level. The peneplain can be uplifted, which starts a second erosion cycle. [5] Davis acknowledged that a full cycle was a special case and that initial uplift was not necessarily rapid or followed by a prolonged period of quiescence.
Because of long and continuous erosion, the whole region has been transformed into an undulating peneplain. This area is interspersed by small monadnocks locally known as tila. Some of the important hills in the area include Ajodhya Hills (677 m), Panchet (643 m), and Baghmundi in Purulia, and Biharinath (452 m) and Susunia (442 m) in Bankura ...
