caption_attribution_description: English: Devil's Peak from the Summit of Table Mountain
context_page_description: Devil's Peak is part of the mountainous backdrop to Cape Town, South Africa. When looking at Table Mountain from the city centre, or when looking at the standard picture postcard view of the mountain, the skyline is from left to right: the spire of Devil's Peak, the flat mesa of Table Mountain, the dome of Lion's Head and Signal Hill.
  The central districts of Cape Town are nestled within this natural amphitheatre. The city grew out of a settlement founded on the shore below the mountains in 1652 by Jan van Riebeeck, for the Dutch East India Company. Some of the first farms in the Cape were established on the slopes of Devil's Peak, along the Liesbeek River.
  Devil's Peak stands 1,000 metres high, less than Table Mountain's 1,087 metres. One can walk to the top but the ascent is more pleasant and safer outside of the cold, wet, winter months of May to August.
context_section_description: The upper, rocky parts of Devil's Peak, Table Mountain and Lion's Head consist of a hard, uniform and resistant sandstone commonly known as the Table Mountain sandstone or TMS. (This is, however, no longer used as a formal geological name). The tough sandstone rests conformably upon a basal shale that in turn lies unconformably upon a basement of older (Late Precambrian) rocks (Malmesbury shale/slate and the Cape Granite). The basal shale and the older rocks below it weather much faster than the TMS and for this reason the lower slopes are smoother in all parts, with few outcrops and deeper soil. Millions of years of erosion have stripped all of the TMS from Signal Hill and that is why it looks very rounded compared to its sister peaks. There is a road that runs almost on the contour from the lower cable station on Table Mountain along the mountain to Devil's Peak. As it turns east around the bulk of Devil's Peak the road cuttings expose a few famous geological unconformities, which illustrate very clearly that the Malmesbury rocks were folded, baked, intruded by granite and planed down by millions of years of erosion before the area sank below the ocean and a new sequence of sediments, including the TMS, began to accumulate.
