A 1:6250 map of the foreland Fláajökull's north lobe as it appeared in 1989, together with a 1:350 scale sample area recently exposed glacial landforms from 2014, enables an assessment spatial and temporal evolution landform assemblages at margin active temperate piedmont terminating ice-marginal thickening till wedges. The pattern development captured these maps indicates that glacier developed strong longitudinal crevassing well-developed pecten (three-dimensional crenulations) during its historical recession. This is recorded by early recessional phase linear push moraines on well-drained distal slopes later interrelated sawtooth moraines, crevasse squeeze ridges eskers, indicative extending ice flow poorly drained submarginal conditions. record palaeoglaciological signature changing process–form regime inherent within landsystem model.
