The Historical Legacies group is a multi-institutional partnership that
uses paleoenvironmental information preserved in tree rings, lake - sediments, archeological and other records to reconstruct climate, vegetation and disturbance history.
Shoring up cases for biosignatures and
paleoenvironmental settings, including comparative studies with Earth analogue samples
using the 2020 instruments, as well as better constraining the age of the deposits (within the early Mars window of wet surface environments), are all tasks ahead.
