Keweenaw's Copper Story

From 7,000 years ago to the 1900s people mined Keweenaw copper. Native peoples made copper into tools and trade items. Investors and immigrants arrived in the 1800s in a great mineral rush, developing thriving industries and cosmopolitan communities. Though the mines have since closed, their mark is still visible on the land and people.

Climate

Lake Superior controls the region's climate. Spring is brief, damp and cool. Summer is sunny and mild with daytime highs in the 70s F near the lake and warmer inland. Fall arrives early in September. Through October the days are usually mild but nights are crisp. The arrival of accumulating snow in mid November means Winter has arrived. The ground is normally covered from Thanksgiving to late April. Average annual snowfall ranges from 180 to 250 inches. Besides creating abundant snowfall, Lake Superior moderates temperatures, making winters milder than in surrounding areas.
