Left aerial view of northeastern Aiguilles Rouges massif in the vicinity of Col des Montets. In red, trace of Remuaz fault, which tends to disappear under late glacial morain deposits. Right topographic cross sections along the lines ab and cd perpendicular to the mean strike of Remuaz fault. The fault zone was entirely covered by ice during the Last Glacial Maximum. The fault scarp is a 40–60 m-high step clearly visible in the landscape. Outcropping striated scarp is only visible to the north in the steepest slope of valley wall (star on the aerial view, section a, b). Inset lower hemisphere stereoplot of strike and dip of striated normal fault plane (in red) together with the rake of the striations (arrow). Strike and dip of steepest local slope is shown in black
