Description

Periodic flood events are normal for rivers. These events sometimes deposit sediments that trap biological remains that can be used to reconstruct the local environment. Following the 2013 flooding of the Highwood River, southwestern Alberta, 24 organic-rich palaeoenvironmental samples were collected from the river’s banks at 14 localities. Data synthesis generated a detectable signal of climatic change throughout the Holocene. The general trend shows a progression from drier conditions in the early Holocene towards relatively moist conditions today. This study is the first detailed examination of near-river palaeoenvironmental conditions in southern Alberta.
