Mount Rainier · Tahoma Glacier
Tahoma Glacier · Westside Road Entrance
The published Emerald Ridge approach uses Tahoma Creek Trail. NPS lists that trail closed because of debris flows and hazardous conditions. The historical climb description is retained below; it is not an open approach.
Checked 2026-10-23 · NPS Trail Conditions ↗The Route
The western route climbs the Tahoma Glacier from Emerald Ridge toward the Sickle and summit cone.

Historical Approach
The published approach begins on Westside Road, follows Tahoma Creek Trail to the Wonderland Trail and reaches Emerald Ridge between the north and south lobes of Tahoma Glacier. NPS now lists Tahoma Creek Trail closed; this explains the historical route, not an available approach.
Camps & Elevation
The guide describes a first camp on Emerald Ridge near 6,100 ft and a second near 10,440 ft, opposite St. Andrews Rock. These are published reference elevations. They do not establish current camp conditions or permit availability.
Glacier & Sickle
The ascent crosses between the glacier’s margins before the upper Sickle and a plateau near 12,600 ft. The source then connects toward the summit cone. This is crevassed glacier and ice terrain, not a fixed trail.
Descent Options
The reference describes either descending Tahoma Glacier or carrying over to Disappointment Cleaver, Camp Muir and Paradise. A carryover finishes at a different trailhead from the western approach.
Emerald Ridge & Glacier Geometry
Emerald Ridge separates the north and south lower lobes of Tahoma Glacier. The historical ascent repeatedly crosses the glacier's width rather than following one bank continuously. Above the second camp, a crevasse moat and upper glacier margins precede the Sickle; the Sickle itself leads to a plateau before a rising traverse toward the summit cone.
Terrain Along the Route
Glacier traverses connect the lower mountain with the upper Sickle.
This is the Tahoma Glacier route, not the South Tahoma Glacier. The old guide’s closed-trail approach is not adopted as current access. Source accounts describe reference terrain, not current route conditions. Reference Set: 2026-10-23.

Route Reference
Historical western route; old Tahoma Creek approach must be reconciled with NPS closures.
