1. Geology on a Digital elevation model. View from south to north. Geology of central uplift is: Orange peak, yellow and dark pink areas at center are Lower to middle Ordovician Limestone. This material was thrust upwards a distance as much as 800m+/-. Light Pink through to orange are Silurian, Devonian and Mississippian strata. Middle Ordovician Strata and above are flanking a ring structure (seen as a topographinc high). Generated by Graham Nickerson at Interactive Visualisation Systems, Fredericton, New Brunswick
