He also showed that scarp retreat in the Grand Canyon is uniform to a first approximation, with some tendency towards more rapid erosion of embayments. These and other theories have been put forth to try to explain the formation of inselbergs. Stripping of regolith (etching) after regolith has been produced by deep weathering.

We define the scarp retreat distance as the distance from our paleoscarp datum to the modern escarpment trend as measured perpendicular to that trend (i.e., at an azimuth of 232°). Eventually the width of the landform is smaller than its height, thus forming a butte.

It was formed at the bottom of a 45 meters high and 500 meters long scarp slope of flat-lying limestones from the Coniacian. The process of scarp retreat and planation is accomplished by sheet wash on non-vegetated surfaces, but it cannot begin until a local base level of erosion-deposition is established. As time goes on, the interfluve is reduced to an inselberg called a monadnock (from Mt Monadnock in New Hampshire, USA, although Mt Monadnock is not formed from scarp retreat, but denudation of softer rocks leaving hard stands of rock). 2) A scarp marked by dissection.

Differences between our rates of surface erosion caused by processes active today and the scarp retreat rates needed to place the escarpment in its present position need to be explained by future work to untangle the mysteries of escarpment evolution. It may be joint controlled, when it is often so abrupt that a boot may barely be placed in it. Different epigene cycle produce different cyclic surfaces.

Pediplanation Theory/ Scarp Retreat (Charles King) King states that inselbergs are created when scarps retreat backwards leaving a vast pediplain in the wake. Furthermore, the pediment surface is apparently being regraded by the process of scarplet retreat and sheetwash, suggesting response to a recent tectonic or climatic change (probably a change to more arid conditions). scarp definition: 1. a steep slope or cliff formed by folded or eroded layers of rock 2. a steep slope or cliff….

Lateral erosion by rivers on valley sides or erosion by sea along cliff foot causes slopes to retreat, however, not all valleys or regions with rivers eroding laterally or sea waves eroding scarps backwards. This theory takes into account deep weathering and mostly occurs in sub-tropical climates where successive periods of wetness and dryness exists. . ." potentiometric surface, erosion surface However, King’s theory has some criticism. No theory is widely accepted as each has its own criticism, thus it still remains a topic of much debate among gemorphologists. Back wasting ² slopes eroding back parallel to their original position, co mmon in dry climates where there is very little surface water runoff, als o known as scarp retreat … AILSA ALLABY and MICHAEL ALLABY "scarp retreat He assumed a homogeneous landscape composed of the same rock type which is not always the case. Several theories on inselberg formation has been envisaged by several geomorphologists such as Charles King, Twidale, Linton and many others. And about 1750 A.D., Glacier Bay was completely filled. Etchplanation makes more sense in explaining inselberg protrusions such as bornhardts, tors or dwalas but not hilly inselbergs. translation and definition "scarp slope", Dictionary English-English online. If deep weathering is faster then the basal surface will not be be exposed to the surface, but rather keeps on lowering. Most online reference entries and articles do not have page numbers. During dry periods erosion and denudation then strips away the regolith revealing seated basal surfaces or weathered boulders as tors.
