A younger version of Ashton at Bals Fiord

Ashton spent almost his entire career working in the Canadian Arctic. His initial adventures involved teasing apart facies and stratigraphy of Devonian reefs, and the clastic wedge that records an outpouring of sediment during the Ellesmerian Orogeny. Following a brief stint in the oil patch, he migrated, like the trajectory of an advancing shoreline, to the Geological Survey of Canada where he honed his sequence stratigraphic skills on Sverdrup Basin, a long-lived (Late Carboniferous – Eocene) depocentre encompassing much of the eastern and central Arctic. Ashton was one of the main instigators of the Transgression-Regression (T-R) sequence stratigraphic model as a viable alternative (and according to him more objective) to the standard Exxon variety and its modifications. It was Ashton who suggested I work on the latest Cretaceous – Paleogene portion of Sverdrup Basin, that gave me the opportunity to work on Ellesmere and Axel Heiberg islands for several years. Thanks mate!
