ABSTRACT: The Frank slide is a rock avalanche that took place in 1903. The aim of this paper is to study the geological features of Turtle Mountain in terms of structural and engineering geology as well as a lithological, granulometrical and morphological description of the deposit. Some modelling (SVR by Matlab) complete the analysis. The results show that part of the fracturing is related to the folding of the anticline and that the hinge area has a large influence on the rock mass quality. The description of the deposit allows making assumptions on the collapse mode.

RÉSUMÉ: En 1903, il s'est produit une avalanche rocheuse connue sous le nom de Frank slide. Cette étude vise à analyser les éléments géologiques qui ont amené à la rupture. De plus, une description granulométrique, lithologique et morphologique du dépôt est réalisée. Des modélisations (SVR par Matlab) complètent l'analyse. Les résultats indiquent que la fracturation est en grande partie en lien avec le plissement de l'anticlinal. De plus, l'influence de la zone charnière du pli sur la qualité du massif rocheux a été démontrée. La description du dépôt permet de proposer un mode d'effondrement.
