Root Glacier

Overview

Root Glacier is the park’s most approachable “walk-on” glacier, starting from historic Kennecott. The trail is generally easy-to-moderate until the final half-mile, where you descend loose moraine to the glacier’s toe. Many hikers call it a trip highlight thanks to turquoise melt pools, rippling ice, and sweeping views of Mt. Blackburn, Regal Mountain, and Donoho Peak.

What You’ll See

• Vivid blue pools, rushing melt streams, and sculpted crevasses and moulins.
• The thundering Stairway Icefall audible from the trail.
• Striking dark debris bands (medial moraines) where rock layers ride atop the ice—“dirty” ice here is still glacier underneath.

Route & Timing

• From Kennecott Mill Town, it’s roughly 1.5–2 miles to the signed left turn for glacier access, then a steep, rocky descent to the ice. Many hikers report the total outing feels like 5–6 miles, depending on how far you explore.
• Budget 2.5–3 hours to reach and enjoy the toe, and add 1–3 hours if you plan to roam on the ice.

Logistics & Access

• You can’t drive to Kennecott. Park by the McCarthy Road footbridge and walk, bike, or take the local shuttle to the mill town trailhead.
• Expect a seasonal crossing of Amazon Creek near the access path.
• Primitive campsites, an outhouse, and food lockers are available near the Root Glacier access; there’s also a pit toilet along the trail.

Safety on the Ice

• Traction is mandatory for walking on the glacier—bring microspikes or crampons, plus trekking poles.
• Avoid the glacier edge (undercut, rotting ice and swift, frigid water), thin snow bridges, moulins, and any blue holes or cracks you can’t see into.
• Surfaces evolve daily; check conditions in Kennecott and consider a guided hike if you’re new to glacier travel.

Wildlife

• Bears live here. Hike in groups where possible, make noise, and carry bear spray. If camping in the area, store food properly.

Best Time to Visit

• Summer into early fall is prime. Start early to enjoy firmer morning surfaces and extra time on the ice.
• Mornings can hold cloud cover; clearer afternoons often reveal the big peaks. Build in shuttle time so you’re not rushing off the glacier.
