Abstract

Dating of dynamic, young (<500 years) geomorphic landforms, particularly volcanofluvial features, requires higher precision than is possible with radiocarbon dating. To estimate the year of landform creation requires that 2 time corrections be added to tree ages obtained from increment cores : 1) the time interval between stabilization of the new landform surface and germination of the sampled trees (germination lag time or GLT); and 2) the interval between seedling germination and growth to sampling height. The sum of these 2 time intervals is the colonization time gap (CTG). Earliest colonizing Douglas fir were sampled for tree-ring dating at 8 sites. Discussion of the results
