The Norse in Greenland had no opportunity. Granite and sandstone boulders are frequently used in cosmogenic nuclide dating, as they have large amounts of quartz, which yields Beryllium-10, a cosmogenic nuclide ideal for dating glacial fluctuations over Quaternary timescales. Geochimica et Cosmochimica Acta 65, 381- 386, , , Seidl, M.\

Sampling and dating boulders in a transect down a mountain will rapidly establish how thick your ice sheet was and how quickly it thinned during deglaciation. I agree that it is too short a record to establish any firm statistical link to other cyclical phenomena. Figure 5 d18O in dark grey right hand scale, d14C in white left hand scale.\

**dating** - Observed variations in the concentration of 10Be and 14C in ice, carbonate and wood therefore record past variations in solar geomagnetism.\
