In principle, dendrochronology disapproves of heteroconnection, that is, the comparison of age-rings of different species for the purpose of dating. It seems, however that there exist extraordinary periods of vegetation whose strong climatic traits produce an effect, be it favorable or unfavorable, which is identical for the age-rings of all species. Identification of these equalconsequent years has made it possible to date sample of cembra pine from the Grindelwald glacial moraine by referring to the chronology of Ernst Hollstein's oaks from west of the Rhine. This dating seems indisputable, having been also confirmed by the radio-carbon method. Heteroconnection is thus possible if certain conditions are respected. It is necessary to remain within a given climatic region, work with a sample of at least 200 age-rings and make sure the data include at least 20% equalconsequent years.

Abstract
In principle, dendrochronology disapproves of heteroconnection, that is, the comparison of age-rings of different species for the
purpose of dating. It seems, however that there exist extraordinary periods of vegetation whose strong climatic traits produce an
effect, be it favorable or unfavorable, which is identical for the age-rings of all species. Identification of these "equalconsequent"
years has made it possible to date sample of cembra pine from the Grindelwald glacial moraine by referring to the chronology of
Ernst Hollstein's oaks from west of the Rhine. This dating seems indisputable, having been also confirmed by the radio-carbon
method. Heteroconnection is thus possible if certain conditions are respected. It is necessary to remain within a given climatic
region, work with a sample of at least 200 age-rings and make sure the data include at least 20% equalconsequent years.
