Grinnell Glacier, Glacier National Park

4.9
#2 of 54 in Trails in Montana
Grinnell Glacier is in the heart of Glacier National Park in the U.S. state of Montana. The glacier is named for George Bird Grinnell, an early American conservationist and explorer, who was also a strong advocate of ensuring the creation of Glacier National Park. The glacier is in the Lewis Range and rests on the north flank of Mount Gould at an altitude averaging 7000ft, in the Many Glacier region of the park.
The glacier has been one of the most photographed glaciers in the park and many of these photographs date back to the mid 19th century. When compared with images taken over subsequent years, the glacier has obviously retreated substantially. In 1850, at the end of what has been referred to as the Little Ice Age, Grinnell Glacier measured 710acre, including the area of The Salamander Glacier, an ice apron or shelf glacier that used to be attached to Grinnell, but is now separate. By 1993, Grinnell Glacier measured 220acre and The Salamander measured 57acre.
Between 1966 and 2005, Grinnell Glacier lost almost 40 percent of its acreage. Glaciologists have predicted that if carbon dioxide levels increase at a worst-case scenario, all the glaciers in the park, including Grinnell, will disappear by the year 2030. However, under a modest increase in overall carbon dioxide levels, some glaciers will remain until the year 2277.

  • The road to the park was limited by the situation of snow, but when I arrived, the lake froze and I was able to skate naturally. Surrounded by magnificent mountains, the scenery is great. There is a café in the park, so you can enjoy the local handmade stuff.

  • We hiked to the lake below and to the glacier. The hike was wonderful and the views were simply amazing. I would say this was an intermediate hike.  more »

  • Amazing. It's a decently hard hike though so make sure you are prepared (Water, food, bear spray.) I would absolutely do this hike again. The views were so spectacular and the wildlife on the trail was awesome. Again, make sure you're ready for an all day adventure.
  • This is such a spectacular Glacier and one of my favorite hikes of anywhere! I wish I could have seen it years ago before it broke off of Salamander, but I am glad I was able to see it while it still existed. I highly recommend this hike. It does get very busy though, so try starting early and hike safe. There is a lot of elevation to get to this point as well, so be ready for that.
