Internal Geometry and Evolution of Moulins
Journal of Glaciology, Vol. 34, No. 117 , 1988 INTERNAL GEOMETRY AND EVOLUTION OF MOULINS, STORGLACVlREN,~DEN By PER HOLMLUND (Department of Physical Geography, University of Stockholm, S-106 91 Stockholm, Sweden) ABSTRACT. The initial conditions needed for formation of moulins are crevasses and a supply of melt water. Water pouring into a crevasse may fill it until it overflows at the lowest point, which is normally near the margin. However, as the crevasse deepens, it intersects englacial channels through which the water can drain. These channels may be finger-tip tributaries in a dendritic system such as that described by Shreve (1972) and observed by Raymond and Harrison (1975). When the crevasse closes, heat in the melt water 'keeps the connection open and a moulin is formed. The englacial channel enlarges rapidly by melting, utilizing mechanical energy released by the descending water. Descents into moulins, and mapping of structures exposed at the surface after many years of melting, demonstrate that the drainage channels leading down from the bottoms of the moulins have inclinations of 0-45 0 from the vertical. These channels trend in the direction of the original crevasse but appear to be deeper than the expected depth of the crevasse. They have not, even at depths of 50--60 m, become normal to the equipotential planes described by Shreve. INTRODUCTION Fig . 1. Map showing the location of Storglaciiiren.

Moulin Work Under Glaciers*
BULLETIN OF THE GEOLOGICAL SOCIETY OF AMERICA VOL. 17, PP. 317-320, PLS. 40-42 JULY 27, 1906 MOULIN WORK UNDER GLACIERS* BY G. K. GILBERT (Read before the Cordilkran Section of the Society December SO, 1905) CONTENTS Page Statement of the problem studied.................... 317 Origin of the rock sculpture.............................. 317 The moulin, or glacial m ill................................ 318 Explanation of plates........................................... 320 S tatem en t o r t h e P roblem studied In glaciated regions I have several times encountered an aberrant and puzzling type of sculpture. Inclined surfaces, so situated that they can not have been subjected to postglacial stream scour, are sometimes carved in a succession of shallow, spoon-shaped hollows, and at the same time are highly polished. They resemble to a certain extent the surfaces some times wrought by glaciers on well-jointed rocks, where the hackly charac ter produced by the removal of angular blocks is modified by abrasion; but they are essentially different. Instead of having the salient elements well rounded and the reentrant angular, they have reentrants well rounded and salients more or less angular; and they are further distinguished by the absence of glacial striae. An example appears in the foreground of plate 40, representing the canyon of the South fork of the San Joaquin river, in the heart of the glaciated zone of the Sierra Nevada. The peculiarly sculptured spot is high above the river. Or ig in of t h e R ock Sculpture The key to the puzzle was found on a dome of granite standing at the southwest edge of Tuolumne meadow, Sierra Nevada, just north of the Tioga road. -

Portrait of Mary Anning, in oils, probably painted by William Gray in February, 1842, for exhibition at the Royal Academy, but rejected. The portrait includes the fossil cliffs of Lyme Bay in the background. Mary is pointing at an ammonite, with her companion Tray dutifully curled beside the ammonite protecting the find. The portrait eventually became the property of Joseph, Mary‟s brother, and in 1935, was presented to the Geology Department, British Museum, by Mary‟s great-great niece Annette Anning (1876-1938). The portrait is now in the Earth Sciences Library, British Museum of Natural History. A similar portrait in pastels by B.J.M. Donne, hangs in the entry hall of the Geological Society of London. -
