This paper proposes a review of the use of lichenometry in Iceland since , using different techniques to solve the chronology of geomorphic processes. Based on the results of over 35 published studies, lichenometry has been widely applied in Iceland, proposing numerical ages absolute dating and relative ages relative dating of different surfaces. Increasing awareness of methodological limitations of the technique, together with more sophisticated data processing, has led some authors to claim that lichenometric 'ages' are robust and reliable. However, the different measurement techniques used make it difficult to compare regions or studies in the same area. These problems are exacerbated in Iceland by rapid environmental changes across short distances and more generally by lichen species mis-identification in the field.

In Iceland, there are numerous examples of glacier advances dated to the latter half of the last century. However, in marked contrast to the Alps and northern Europe, the record of historical-age moraines before ca. This paper examines to what extent this pattern reflects the actual history of glacier fluctuations, and to what extent it could be a function of preservation and dating of the geomorphological record. Measurements of Rhizocarpon geographicum sp. Recent studies have converged on the view of a maximum glacier extent in the late nineteenth century, and not during earlier and possibly colder parts of the "Little Ice Age". A mid-eighteenth century glacial maximum may be better represented in the landform record than hitherto thought, with implications for reconstruction of North Atlantic circulation patterns.

DOI: This commentary article discusses the relative merits of new mathematical approaches to lichenometry. It highlights their strong reliance on complex statistics; their user unfriendliness; and their occasional mistreatment of existing lichenometric techniques.
There is not much people know about Iceland in general. It is a tiny country located on an island, it is a part of Europe and thousands of tourists come here for the beautiful nature. But what about people of Iceland? What is their typical behaviour? What do they like?
