A glacial period is an interval of time within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate within an ice age. The last glacial period ended about 10,000 to 15,000 years ago; the current Holocene epoch is the interglacial we are presently in.

The Alps (German: Alpen; Italian: Alpi; Western Lombard: Alp; French: Alpes; Occitan: Aups/Alps; Romansh: Alps; Slovene: Alpe) are one of the great mountain range systems of Europe, stretching from Austria and Slovenia in the east; through Italy, Switzerland, Liechtenstein and Germany; to France in the west.

The Anglian Stage is the name for a middle Pleistocene stage used in the British Isles. It precedes the Hoxnian Stage and follows the Cromerian Stage in the British Isles. The Anglian Stage is equivalent to the Elsterian Stage of northern Continental Europe, the Mindel Stage in the Alps and Marine Isotope Stage 12.[1][2][3] The Anglian Stage and Marine Oxygen Isotope Stage 12 started about 478,000 years ago and ended about 424,000 years ago.[4][5]

Annum is a form of the Latin noun annus meaning year, from which are derived words such as annual and annuity. Annum is the accusative singular of the 2nd declension masculine noun annus (nominative singular: this is the reference form of the word), anni (genitive singular and nominative plural). Thus it is synonymous with year.Anthropogenic (from the Greek meaning manmade) effects, processes or materials are those that are derived from human activities, as opposed to those occurring in biophysical environments without human influence.

Arrowhead Provincial Park is located north of Huntsville, Ontario, Canada, and is part of the Ontario Parks system. A portion of the shoreline from the Glacial Lake Algonquin is visible in the park.[1]The Beestonian Stage is the name for an early Pleistocene stage used in the British Isles. It precedes the Cromerian Stage and follows the Pastonian Stage. This stage consists of alternating glacial and interglacial phases instead of being a continuous glacial epoch. It is equivalent to the European Bavellan, Waalian, and Eburonian stages combined and Marine Isotope stages 22 to (60?).[1][2][3] The Beestonian Stage and Marine Isotope Stage 22 ended about 866,000 years ago.[4][5]Before Present (BP) years is a time scale used in archaeology, geology, and other scientific disciplines to specify when events in the past occurred. Because the "present" time changes, standard practice is to use 1 January 1950 as the arbitrary origin of the age scale. For example, 1500 BP means 1500 years before 1950, that is, in the year 450.
