[2] 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.

Repeat photography taken between the years 1938 and 2009 (as shown below) show that Grinnell Glacier has retreated significantly over that period.

The Salamander and Gem Glaciers have shown little change in area over the same period of time.

The Salamander receives its name for its shape and its coloring, which comes from the serratia bacteria that grows on it.

The glacier can be reached after a 6-mile (9.7 km) hike from a trailhead beginning at Swiftcurrent Lake.
