Gallatin Mountains

 

The Gallatin Range is a mountain range of the Rocky Mountains, located in Montana and Wyoming. It includes more than 10 mountains over 10,000 feet and the highest peak in the range is Electric Peak at 10,969 feet.

 

The Gallatin Range was named after Albert Gallatin, the longest-serving US Secretary of the Treasury and one of the negotiators of the Alaska Boundary Treaty. The range extends 75 miles north to south and averages 20 miles in width.

 

In the lower Highlight Canyon, there are multiple outcrops of the basement complex. The rocks there consist of mainly garnet bearing granitic gneiss that has been heavily folded and metamorphosed during the Laramide orogeny.
