Overview

About Emmons Moraine Trail

Why go

  • Views of Emmons Glacier and a turquoise moraine lake
  • A gradual forest approach before a short, rougher climb

Heads up

  • The final spur is rocky, steep and loose
Emmons Moraine Trail is a 3-mile out-and-back from Loop D at White River Campground to a ridge with views of Emmons Glacier and an unnamed turquoise lake. The first mile shares Glacier Basin Trail and climbs gradually through forest; the last half-mile leaves the smoother tread for boulders, a log bridge and steep switchbacks. It is a good choice for a close glacier view without hiking all the way to Glacier Basin. Plan on about two hours and roughly 700 feet of climbing; the loose descent and the viewpoint can stretch that out.

Before you go

Parking

Use the designated hiker and climber lot at the end of Loop D in White River Campground; do not park in a campsite. A park entrance fee or pass is required.

Safety

The boulder crossing and log bridge can be difficult when water is high, and the short switchbacks are steep and loose. Stop at the End of Maintained Trail sign; unofficial paths toward the lake are hazardous. There is no potable water at the campground.

“White River Campground is ahead, a forested base beside the river below Sunrise. For a day visit, there's a separate picnic area, and the historic patrol cabin in Loop D is worth a short look.”

Hiking Emmons Moraine Trail

The approachStart at the hiker and climber parking area at the end of Loop D, not in a campsite.

Start at the hiker and climber parking area at the end of Loop D, not in a campsite. The broad dirt path follows the Inter Fork of the White River through forest. It was once a mining road, so this first stretch is a steady, uncomplicated walk beside the river. There is no potable water at the campground.

The moraine spurAfter about a mile, take the left fork for Emmons Moraine.

After about a mile, take the left fork for Emmons Moraine. The path narrows across boulders before reaching a log bridge over the river. Water levels vary, and the crossing can be difficult in some conditions. After the bridge, a short set of steep, loose-dirt switchbacks climbs to the moraine ridge; take extra care on the way down.

Stop at the maintained-trail signThe marked route ends at a signed viewpoint.

The marked route ends at a signed viewpoint. From there you can look across the turquoise lake and toward the glacier, but there is no official trail down to the lake. Faint tracks beyond the sign cross steep, unstable ground; don't follow them. From the maintained ridge, frame the turquoise lake below the debris-covered glacier to show both the water and the moraine that holds it back.

Why the lake is turquoiseThe lake is unnamed.

The lake is unnamed. A moraine left by the retreating glacier blocks its meltwater, and fine glacial silt gives the water its blue-green color. Emmons is the largest glacier on Mount Rainier and the largest in the contiguous United States. Rock debris from a December 1963 fall off Little Tahoma covers much of its lower surface, insulating the ice beneath it.

Before you goA park entrance fee or pass is required, and pets aren't allowed on park trails.

A park entrance fee or pass is required, and pets aren't allowed on park trails. The route is generally snow-free from July into October, though snowmelt can make the river crossing harder. Use the designated hiker and climber lot rather than a campsite, and check current road and trail conditions before setting out.
