. We present new 10Be surface exposure ages from two selectedlocations in southern Norway. A total of five 10Be samples allow a firstassessment of local deglaciation dynamics of the Scandinavian Ice Sheet atDalsnibba (1476  m  a.s.l.) in southwestern Norway. The bedrock ages from thesummit of Dalsnibba range from 13.3±0.6 to 12.7±0.5 ka and probably indicate the onset of deglaciation as a glacially transportedboulder age ( 16.5±0.6 ka ) from the same elevation likely showsinheritance. These ages indicate initial deglaciation commencing at the endof the Bolling–Allerod interstadial ( ∼  14.7–12.9  kyr  BP)and ice-free conditions at Dalsnibba's summit during the Younger Dryas.Bedrock samples at lower elevations imply vertical ice surface lowering downto 1334  m  a.s.l. at 10.3±0.5 ka and a longer overall period ofdownwasting than previously assumed. Two further 10Be samples add tothe existing chronology at Blaho (1617  m  a.s.l.) in south-central Norway. The 10Be erratic boulder sample on the summit of Blahosample yields 20.9±0.8 ka , whereas a 10Be age of 46.4±1.7 ka for exposed summit bedrock predates the Late Weichselian Maximum.This anomalously old bedrock age infers inherited cosmogenic nuclideconcentrations and suggests low erosive cold-based ice cover during the Last Glacial Maximum.However, due to possible effects of cryoturbation and frost heave processesaffecting the erratic boulder age and insufficient numbers of 10Be samples, the glaciation history on Blaho cannot conclusively beresolved. Comparing the different timing of deglaciation at both locationsin a rather short west–east distance demonstrates the complex dynamics ofdeglaciation in relation to other areas in southern Norway.
