Doggerland: Doggerland was an area now beneath the southern North Sea that connected Great Britain to continental Europe during and after the last glacial period.  It was flooded by rising sea levels around 6,500–6,200 BCE.  Geological surveys have suggested that it stretched from Britain's east coast to the Netherlands and the western coasts of Germany and the peninsula of Jutland.  It was probably a rich habitat with human habitation in the Mesolithic period, although rising sea levels gradually reduced it to low-lying islands before its final submergence, possibly following a tsunami caused by the Storegga Slide.

Mount Cayley volcanic field: The Mount Cayley volcanic field is a remote volcanic zone on the South Coast of British Columbia, Canada, stretching 31 km from the Pemberton Icefield to the Squamish River.  It forms a segment of the Garibaldi Volcanic Belt, the Canadian portion of the Cascade Volcanic Arc, which extends from Northern California to southwestern British Columbia.  Most of the Cayley volcanoes were formed during periods of volcanism under sheets of glacial ice throughout the last glacial period.  These subglacial eruptions formed steep, flat-topped volcanoes and subglacial lava domes, most of which have been entirely exposed by deglaciation.  However, at least two volcanoes predate the last glacial period and both are highly eroded.  The field gets its name from Mount Cayley, the largest and most persistent volcano, located at the southern end of the Powder Mountain Icefield.  This icefield covers much of the central portion of the volcanic field and is one of the several glacial fields in the Pacific Ranges of the Coast Mountains.

Glacial period: A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances.  Interglacials, on the other hand, are periods of warmer climate between glacial periods.  The last glacial period ended about 15,000 years ago.  The Holocene epoch is the current interglacial.  A time when there are no glaciers on Earth is considered a greenhouse climate state.

Storegga Slide: The three Storegga Slides are considered to be amongst the largest known landslides.  They occurred under water, at the edge of Norway's continental shelf in the Norwegian Sea, approximately 6225–6170 BCE.  The collapse involved an estimated 290 km length of coastal shelf, with a total volume of 3500 km3 of debris, which caused a very large tsunami in the North Atlantic Ocean.

History of England: England became inhabited more than 800,000 years ago, as the discovery of flint tools and footprints at Happisburgh in Norfolk has revealed.  The earliest evidence for early modern humans in North West Europe, a jawbone discovered in Devon at Kents Cavern in 1927, was re-dated in 2011 to between 41,000 and 44,000 years old.  Continuous human habitation in England dates to around 13,000 years ago (see Creswellian), at the end of the last glacial period.  The region has numerous remains from the Mesolithic, Neolithic, and Bronze Age, such as Stonehenge and Avebury.  In the Iron Age, England, like all of Britain south of the Firth of Forth, was inhabited by the Celtic people known as the Britons, including some Belgic tribes (e.g. the Atrebates, the Catuvellauni, the Trinovantes, etc.) in the south east.  In AD 43 the Roman conquest of Britain began; the Romans maintained control of their province of Britannia until the early 5th century.

Last glacial period: The last glacial period, popularly known as the Ice Age, was the most recent glacial period, which occurred from years ago.  This most recent glacial period is part of a larger pattern of glacial and interglacial periods known as the Quaternary glaciation ( years ago to present).  From this point of view, scientists consider this "ice age" to be merely the latest glaciation event in a much larger ice age, one that dates back over two million years and is still ongoing.

Wisconsin glaciation: The Wisconsin Glacial Episode, also called the Wisconsinan glaciation, was the most recent glacial period of the North American ice sheet complex.  This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide ice sheet, which covered the high latitudes of central and eastern North America.  This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation.  The Wisconsin glaciation extended from approximately 85,000 to 11,000 years ago, between the Sangamon interglacial (known globally as the Eemian stage) and the current interglacial, the Holocene.  The maximum ice extent occurred approximately 25,000–21,000 years ago during the last glacial maximum, also known as the "Late Wisconsin" in North America.

Llanquihue glaciation: The last glacial period and its associated glaciation is known in southern Chile as the Llanquihue glaciation (Spanish: "Glaciación de Llanquihue" ).  Its type area lies west of Llanquihue Lake where various drifts or end moraine systems belonging to the last glacial period have been identified.  The glaciation is the last episode of existence of the Patagonian Ice Sheet.

Stone Spring: Stone Spring is a 2010 novel by Stephen Baxter.  It is set in prehistoric Doggerland (renamed "Northland" in the novel) and focuses on the attempts of Northland's inhabitants to adapt to the rising sea levels slowly eroding Northland's coastline.  It is the first part of a trilogy detailing an alternate history in which human efforts were able to prevent Doggerland from being flooded.

Geology of southern North Sea: The North Sea basin is located in NE Europe and lies between the United Kingdom, and Norway just north of The Netherlands and can be divided into many sub-basins.  The Southern North Sea basin is the largest gas producing basin in the UK continental shelf, with production coming from the lower Permian sandstones which are sealed by the upper Zechstein salt.  The evolution of the North Sea basin occurred through multiple stages throughout the geologic timeline.  First the creation of the Sub-Cambrian peneplain, followed by the Caledonian Orogeny in the late Silurian and early Devonian.  Rift phases occurred in the late Paleozoic and early Mesozoic which allowed the opening of the NE Atlantic.  Differential uplift occurred in the late Paleogene and Neogene.  The geology of the Southern North Sea basin has a complex history of basinal subsidence that had occurred in the Paleozoic, Mesozoic, and Cenozoic.  Uplift events occurred which were then followed by crustal extension which allowed rocks to become folded and faulted late in the Paleozoic.  Tectonic movements allowed for halokinesis to occur with more uplift in the Mesozoic followed by a major phase of inversion occurred in the Cenozoic affecting many basins in NW Europe.  The overall saucer-shaped geometry of the southern North Sea Basin indicates that the major faults have not been actively controlling sediment distribution.
