Mount Jackson is located in Glacier National Park in northwest Montana. Jackson is the 4th highest peak in the park, and is one of only six peaks in the park over 10,000 feet elevation. As the third highest mountain in the Lewis Range, Jackson is situated directly on the Continental Divide. The sedimentary rock of Mount Jackson was shaped by 1.6 billion years of geologic processes from sediment deposition, uplift, thrust faulting, and erosion by glaciers. The major geologic event that sculpted the landscape of Mount Jackson and the other peaks in Glacier National Park began approximately 2 million years ago when large ice sheets of the Pleistocene Ice Age repeatedly advanced and retreated until about 12,000 years ago. Most of the glaciers in the park are located in the vicinity immediately around Mount Jackson. The largest glacier in the park is the Blackfoot Glacier, measuring some 3 square miles, and is located in a depression between Mt. Jackson and Blackfoot Mountain. There are other significant glaciers on Mt. Jackson including the Harrison Glacier on the south slope, and the Jackson Glacier to the east slope, both of which are receding like most of the glaciers in the park due to global warming.
Mount Jackson is named for William Jackson, famous scout and grandson of Hugh Monroe. (Hugh Monroe was one of the earliest, if not the earliest, white man to see much of the area contained in the eastern portion of what is now Glacier National Park). Jackson was quarter-breed Piegan and was a scout with Captain Reno at the time of the Custer Battle, on the Little Big Horn. Mount Jackson was named by G. B. Grinnell. (reference NPS)
