History of West Falkland

abundance of seabirds. To the west are some white sandy beaches with beautiful clean water and rolling sand dunes with tall grass. Set just back from the top of the cliffs is a single wooden hut locally referred to as Uncle Tom's Cabin. The beaches are a habitat for elephant seals and are unpolluted save for the occasional piece of wreckage and the odd washed-up tree trunk.

Most of the layers of West Falkland and its surrounding islands are slightly inclined from the horizontal. This inclination shows different types of rocks in different places. The quartzites of Port Stephens and Stanley are more resistant than the are naceous sediments of the formation at Fox Bay. The Hornby Mountains, near Falkland Sound have experienced tectonic forces of uplift and folding which has inclined the quartzite beds of Stanley to the vertical.

In West Falkland there are several dykes that cut the rocks of the western islands, but these dykes, unlike the previous ones, are chemically more unstable and have been eroded. The only indications of their existence are the aligned linear depressions. In the margins of these depressions there is evidence of contact baking or hornfels formation adjacent to the once molten basalt dyke
