The North York Moors National Park is formed from Jurassic age sandstones, mudstones and siltstones and limestones, many of which are well exposed in the cliffs of the park's North Sea coast (which is often referred to as the 'Dinosaur Coast'. The southerly regional dip of the rock strata has produced a landscape of multiple scarps and dip-slopes with the older rocks exposed in the north and progressively younger ones to the south such as the Tabular Hills formed from late Jurassic age limestones. The moors were not glaciated during the last ice age but ice sheets surrounded the area and led to the formation of glacial lakes around the hills and the development of major meltwater channels such as Newton Dale.
