Wheeler Peak Summit Trail Closed
A small smoldering fire near the trail has caused the closure of the Wheeler Peak Summit Trail. park staff is observing the fire. Check back here to get an update whne the trail will open. Alpine Lakes Loop and Bristlecone Trail are open. More »
Road Work at Great Basin National Park
Road work will begin in Upper Lehman and Wheeler Peak Campgrounds. Campgrounds will be open but may be noisy and have large vehicles on the roads. The Scenic Drive is open with up to 15 min delays due to road work. Click more for details. Updated 9/9/14 More »
Travel Not Recommended - Wheeler Peak Scenic Drive Above 8,000 Feet
Snow and ice may make travel on Wheeler Peak Scenic Drive unsafe, travel is not recommended at this time. Warmer weather later in the week is expected and conditions may improve. Please check back. 9/29/2014
Snake Creek Road and Campsites Closed
The Snake Creek Road will be closed from the park boundary into the park to begin work on campsites, trails and restroom improvements. Work will continue until snow closes the project. Work will resume in Spring 2015.
Glaciers / Glacial Features
Great Basin National Park is home to the only glacier in Nevada, and one of the southernmost glaciers in the United States. The Wheeler Peak Glacier sits at the base of Wheeler Peak, in a protected cirque around 11,500 feet in elevation. The glacier measures 300 feet long and 400 feet wide. Exact depth is unknown.
There are two types of glaciers. Contintental ice sheets cover large areas with ice. Alpine glaciers, like the Wheeler Peak Glacier, are smaller, and found in mountainous terrian.
During the last glacial period, glaciers moved down to as low as 9,200 feet. The climate was an average 8 degrees (F) cooler than today. But climate changes that began with the Holocene period (10,000 years ago) rapidly warmed the region, melting the continental glaciers to the north, and the individual alpine glaciers within the region. The Wheeler Peak Glacier is the last alpine glacier to survive. With continued warming predicted, it is likely the glacier will disappear in as little as 20 years.
Ice Field or Rock Glacier?
It has correctly been referred to as a rock glacier, however. A rock glacier is a lobe of angular boulders and cobbles that resembles an alpine glacier in outline and in its slow downslope movement. They are found in mountain ranges throughout the world. Inside a rock glacier, ice fills the spaces between the blocks. By freezing, thawing, and sagging, the ice works with gravity to provide the force that moves the rock glacier.
Viewed from the cliffs above, arc shaped ridges are visible on the surface of the Wheeler Peak Glacier. These ridges are curved because the blocks near the midline of the rock glacier are creeping faster than those on either side.
The Wheeler Peak Overlook on the Wheeler Peak Scenic Drive is the only vantage point from the road. The glacier is seen at the bottom of the sheer rock face of Wheeler Peak.
The Bristlecone/Glacier Trail (4.6 miles roundtrip) will take you to the foot of the glacier. The trailhead for this hike is located at the end of the Wheeler Peak Scenic Drive. The trail begins at an elevation of 9,800 feet and climbs another 1,100 feet. Use caution around the toe of the glacier, as the boulders may not be stable, and small rockslides are common from the cliffs above.
