Bothnia Ice Lake

During the Stone Age when humans ventured along the shores of the Bothnia Ice Lake around 10000BC, it was most likely during the spring or a summer season. Travelling on water by boat or canoes for easy travel and transportation of the animal furs and the meat they caught. Like many other human endeavors searching for food and clothing materials: they went out hunting, fishing, foraging and trapping into the Nordic/Arctic region. How far and how long time their endeavors lasted per trip is unknown, within a small community, there was no need to be gone for a long time. Food supplies and clothing materials for a small group could have been serviced within a comfortable radius.

During the Bronze Age (4000-3000 BC), the world population rose from 7Million to 14Million and grew further to 30 Million during the 3000 to 2000 BC. On the centre stages of the world civilization at the time, e. g. Iraq and Egypt the rise of intellectual writings/knowledge and physical architecture often was a source of friction on a political stage. Many rising rulers sought after for more resources and power. Along came leaders with mega enthusiasm and ambitious plans for bigger and better architecture, imperialism, organized absolutism and internal revolution. The 120+ discovered pyramids, built in Egypt between 3000 BC 1000BC were mostly built and used as tombs for the nation?s Pharaohs and their consorts during the Old and Middle Kingdom periods. Grand plans require enormous effort and sacrifice from the labor sources that produce them.

The nomadic tribes that ventured into the Nordic region at the same time were free and naturally interacting with the surrounding environment. It required of them to be of strong spirit, alert and observing the surroundings environment, efficient hunters and many food preparation skills. They needed to find food to eat, cook food and store the food items, both cooked and raw ingredients. They much depended on their fishing skills, hunting skills, spirit, physical strength, nutrition, health and stamina. Their purpose in life was not to build pyramids in the heat of Egypt, but to travel and to boat along the unknown wilderness of their Nordic region. At the same time as the Biblical Abraham was a lad, and learning to run like boys do, there were young children running around also along the banks of the Ice Lake.

The Baltic Finns had a call of the wild in their blood, and the excitement of adventure, to go out and explore the wild North of the Nordic region. There were many real dangers lurking in the dark of the backwoods of the Nordic region. The flat terrain of the lake country with peat covered swamps and bogs, surrounded by thick forest cover and thickets, spring and autumn fogs, winter darkness, possible early snow falls and the bitter cold, it all increased to the risk of getting lost. The elements of nature and also natural predators; roaming brown bears, howling wolves and the charge pointed antlers of a wounded deer, was a real life threatening challenge during the Stone Age, when they faced the wild predators with the burnt sharp tips of the wooden spears, hefty clubs, bone edge knives and stone tipped arrows.

Their natural instincts came to the forefront, to search and to hunt, to fish and to find a suitable protective location where they and family, tribe and community would survive in relative comfortable conditions. Their journey along the meandering shorelines of endless lakes, peat bogs, marshes and swamps. There was a time for chopping down trees, building houses, building rafts/boats, and a time for planting seeds and a season for picking berries and mushrooms. Also, time for catching fish, hunting and trapping fur animals, and exploring the unknown, not knowing what lay on the other side, and making sure to survive at times of danger and through the extreme cold of the sub-Arctic winter. The many islands on the waters would have been attractive place to go to during the spring and summer season. Fresh water supply, fishing and migrating birds with their supply of eggs, swans, geese, ducks and many other water birds to loot and hunt. Nomadic tribes moving on as nature provided and supply needs demanded.

Geological change

Without a doubt, the most spectacular natural geologic change was the glacial maximum (Big freeze), and how the surrounding ocean levels dropped dramatically. It was followed by the global warming and the retreat of the glacial ice cap, and it caused the dramatic transformation of ice into the water, which in effect created the inland Ice Lake at the current Sea of Bothnia. The slow ebb and flow of water over land, over the glacier depressions, wet lands, marshes, peat bogs, lakes, ponds, dams and the moss covered grounds in the forest. What followed was a quick release of the slow invasion of water over land. When the dam walls broke the water level started to go down gradually, and over time, the geography was changed forever. (Gothenburg)

The land bridge (Karelia isthmus) was submerged by the rising Ice Lake waters, covering the Bothnia Ice Lake to the Lake Ladoga, release of the natural dam, Ice Lake water dropped and the land appeared once again with dead trees and layers of silt from the decayed flora and runoff from the melting glaciers. The force of gravity was once again pulling on the waters of Lake Ladoga down along the Neva River, the birth and the subsequent drainage of LakeLadoga that caused a ten meter drop in the water level, the recent/new studies show that took place several thousand years BC.

Heikki Simola in Finland led a series of research projects, a newchapter on the Karelian study of geology. Ojala, 2001.

Heikki Simola article; Karelian Nature and man. The research results reveal that some of the oldest land marks range from the Bronze Age to a few hundred years BC. There are signs of agriculture in the middle Iron Age AD 400-600, and discovering the beginning of agriculture in the Karelian region on thenorth coast of Lake Ladoga to the Viking era until the 1000s AD. Archaeology finds range from the Stone Age more than 10 000 years ago, to the Crusade of the Karelia during the early Middle Ages 1300-1400 AD. Ojala

The geological change that occurred controlled the waters of Lake Ladoga through the border-river (Rajajoki) and the larger Neva-river between lake Ladoga and the Gulf of Finland.

The first residence of the Stone Age study was conducted in Finland in 1892 and 1900, Raisala, city of Vyborg and Hayrynmaella. OKSANEN, 2002.
