Abstract. Historical documentary records contain valuable information on
climate, weather, and their societal impacts during the pre-instrumental
period, but it may be difficult to assess the objectivity and reliability of
this information, particularly where the documentary record is incomplete or
the reliability of the information it contains is uncertain. This article
presents a comprehensive review of information relating to drought found in
original written records concerning all early European expeditions
(1510–1610 CE) into the present-day US and Canada, and compares this information
with maps and time series of drought generated from the tree-ring-based
North American Drought Atlas (NADA). The two sources mostly agree in the
timing and location of droughts. This correspondence suggests that much of
the information in these early colonial historical records is probably
objective and reliable, and that tree-ring-based drought atlases can provide
information relevant to local and regional human historical events, at least
in locations where their reconstruction skill is particularly high. This
review of drought information from written sources and tree-ring-based
reconstructions also highlights the extraordinary challenges faced by early
European explorers and colonists in North America due to climatic
variability in an already unfamiliar and challenging environment.
