Postglacial Recession of Niagara Falls in Relation to the Great Lakes
The recessional history of Niagara Falls in the present Niagara Gorge during the postglacial period has been a focus of study throughout this century. Radiocarbon ages of clam shells suggest that Niagara Falls migrated very slowly around the narrowed gorge section at Niagara Glen from 10,500 to 5500 yr B.P., when upper Great Lakes water bypassed Lake Erie and flowed to the Ottawa River via the outlet at North Bay, Ontario. Prior to that interval,…

History of Geomorphology
Canadian Landform Examples ‐ 2 Niagara Falls
Niagara Falls (Figure 1) merits discussion on at least three points: its role in eighteenth‐ and nineteenth‐century controversies about the age of the earth and the origin of valleys, the response of the gorge to regional deglaciation, and as an illustration, perhaps atypical, of the dynamics of waterfall recession
Postglacial Temperature Anomalies and Glacial Isostasy
The isostatic depression of an ice-free land surface, originally caused by glacial ice, ought to be converted into a change in mean annual temperature according to the usual value for the environmental lapse rate, 6.5°C/1000 m. Calculations are undertaken to show the temperature changes, relative to present values at a site, that can be expected from this effect during the retreat of a major continental ice sheet. It is concluded that when restra…
Route Factors in Grid Systems 'Pushed Over' by φ Degrees
Route factors are obtained for biaxial grid systems, of infinitely fine mesh, which have been 'pushed over' by φ degrees. The results assume that trip origins and destinations are uniformly distributed over the plain
Graph theory
On the Choice of Methods in the Factor Analysis of Connectivity Matrices
The basic difficulty in the interpretation of eigenfunctions is that our concept of'structure' is weak and that our normative expectations of structure are not clear. The interpretations in such analyses might best look for a low connectivity common structure, the direction of the sign to distinguish nodes, and the appearance of linear sub-systems. The alternative interpretations of Gould's method is merely a matter of personal preference. I AM g…

Slope Profiles and Scree in the Eglwyseg Valley, North Wales
The eglwyseg limestone escarpment extends north from Castell Dinas Bran near Llangollen for nearly 5 miles to World's End, facing westwards but divided into a series of buttresses by deep gully dissection. It is frequently quoted as a type example for escarpments and screes but it differs markedly from the form and history of many others in Upland Britain (Wood, Holmes, Dury). It was therefore chosen for an investigation of slope form, and partic…
