[Extract] Denniston et al. (1) provide an important contribution to the prehistoric record of rainfall and tropical cyclones (TCs) in northwest Australia. The authors identify mud layers within limestone stalagmites as evidence of cave flood events and associate these with the passage of TCs. There is little doubt that the prominent thicker layers of mud, some of which occur on the flanks of the stalagmites, were deposited during cave flood events. The methodology used to identify the other reported thinner (<0.5 mm) mud layers, however, is not clearly articulated. Nor is it clear if an objective methodology was used to identify flood layers that may be only several tens of microns thick.
