The Brooks Range was formed primarily through tectonic activity, specifically the collision of the North American and Eurasian tectonic plates. This collision, which began around 100 million years ago, led to the uplift of the mountains as sediments were compressed and folded. Additionally, glacial and erosional processes during the last Ice Age further shaped the range, creating its current rugged topography. Today, the Brooks Range stretches over 700 miles across northern Alaska, serving as a key geographical feature of the region.
