Emmons Moraine Trail - 4.0 Miles Round-Trip
Emmons Glacier (4.3 sq miles) is the largest of Mount Rainier's 25 named glaciers, and largest glacier in the contiguous US. It extends from the summit and forms the White River, one of five major river systems emanating from the mountain.
Glacial movement grinds the land beneath it, depositing till on its margins that accumulate on ridges called moraines. Emmons Moraine is an archetypal lateral moraine on the north side of Emmons' terminus.
The Emmons Moraine Trail runs up the moraine's high, steep spine with useful insight to the glaciers formation and 3+ mile path from summit to river.
Views of the glacier are concentrated on its terminus, which is covered by debris from a 1963 rockfall off Little Tahoma. This coverage has insulated the ablation zone and slowed melting, resulting in periods of glacial advance and irregular melting patterns under the debris.
Note that trail maintenance ends .5 miles from the Glacier Basin Trail split, but a serviceable path continues further up valley. Travel beyond this point is rugged and moraine edges can be unstable - use caution:
The Glacier Basin Trail heads west on a mild grade over Inter Fork, which joins the White River near the campground. It rises fast to panoramas of Rainier, Goat Island Mountain and the White River just before reaching the Emmons Moraine Trail split (1.05 miles : 4,845').
The Emmons Moraine Trail drops across the cobbled channel of Inter Fork on a footbridge and switchbacks to the top of the moraine. You'll have good views of White River and a lake formed by a terminal moraine from this point, though access to both is deliberately blocked.
It levels on the moraine to the End of Maintained Trail Sign (1.55 miles : 5,035'), but several clearly defined paths continue up-valley along the spine. Scrambling down to the river is not advised due to steep, unstable terrain and falling rock.
The most usable path drops off the spine and shifts erratically through tightly packed vegetation with minimal clarity (2.1 miles : 5,230'). It edges back to the moraine-top with good views, but quickly fades in rugged terrain (2.3 miles : 5,315'). Further travel is difficult with minimal payoff.
