The occurrence of the ice age left BC, Canada approximately 20,000 centuries ago. Scientific research estimates that the earth’s orbit and carbon dioxide helped end the ice age. The rising of carbon dioxide helped raise ocean levels which raised sea levels. All of these actions helped end the ice age. As the glaciers melted, plant life resurged; animals began the migration north, sea life emerged. People followed life forms north; they began to search for the lands they had heard of in legends and stories passed down by the ancestors. In the migration north in search of food; freedom to live life in peace and harmony and live in a mild climate, Squamish ancestors continued their search over several generations. Some people settled in North West area of the United States. Young people developed a wanderlust, and a large group continued north.
