Leading edge to the left trailing to the right. These distinctive glacial features are formed when the moving ice sheet passes over exposed lumpy bedrock. The ice is forced up the rock and smooths and scores as it goes, giving a gently sloping profile on the leading edge. However at the rear of the rock there is little support for the bedrock and it tends to get plucked off bit by bit leaving a sharp edge and a steeper face. From above the roches look like an arrow head in plan and they point into the direction in which the ice sheet passed over them. In this area it is estimated that the ice sheet was up to around 700mts thick.
