Ice Lake Trail
Length from Ice Lake Trailhead to:
Ice Lake - 0.3 miles, one way
Wolf Lake - 4.0 miles, one way
Elevation change: Trailhead at 7,800 feet (80-foot gain).
Trailhead: The trailhead is 3.25 miles east of Norris Junction on the Norris Canyon Road, and the parking area is an unmarked turnout near the exit of the Virginia Cascades road.

The trail is relatively flat and very short, only a 10- to 15-minute hike from the trailhead. The lake itself is lined with subalpine fir and lodgepole pine, but the 1988 fires have affected some areas. Another approach to Ice Lake is via the Norris Campground trail, which is about 4.3 miles. The trail-head is located in the east central edge of the campground. After about a half mile the trail junctions and the southern trail crosses Solfatara Creek, then continues through lodgepole pines, and a meadow before reaching the north side of Ice Lake. Ice Lake and nearby Wolf and Grebe lakes are the headwaters of the Gibbon River, which flows past Norris Geyser Basin and merges with the Madison River at Madison Junction. Ice Lake is fed by underground springs and seepage. Fish have been unable to establish in the lake, even though massive stocking efforts between 1905 and 1961 released nearly 4 million graying, brook trout, cutthroat trout and rainbow trout. Because there is not a constant flowing inlet and outlet, conditions are poor for spawning, leaving the lake barren offish.

During winter, the 224-acre lake freezes over, but not solid. Only the first one to two feet of the 53-foot deep lake freezes; on top of that, four to six feet of snow can accumulate, making the lake appear as a large white field. It was named Ice Lake circa 1900 because nearby Norris Hotel cut its ice supply from this small lake.

On the northwest side of the lake the trail joins the Howard Eaton Trail and continues east to Wolf and Grebe lakes. But the Gibbon River will need to be forded several times before reaching Wolf Lake. This lake is smaller-just a quarter of the size of Ice Lake-but maintains a good population of rainbow trout. They were introduced, along with graying and cutthroat, during the 1920s and 30s. The trout began to hybridize and, by 1969, only rainbow-trout characteristics were found. The large, open, marshy meadows bordering the northwest and southeast shores of Wolf Lake often are occupied by moose, sandhill cranes (in the spring), or great blue herons.


Norris Geyser Basin Trail
Length from Norris parking area to:
Porcelain Basin - 1.6-mile loop.
Back Basin - 2.0-mile loop.
Elevation change: Trailhead at 7,520 feet (40-foot gain).
Trailhead: Located at the Norris Geyser Basin parking area.

This is an exciting and easy hike into an austere but colorful geyser basin. Two trails loop through the basin: The northern loop explores Porcelain Basin; and the southern, longer trail loops through the Back Basin.

Norris Geyser Basin was named after an early Yellowstone superintendent, P.W. Norris, and this basin may be the hottest geyser basin in Yellowstone. The Carnegie Institute of Washington, D.C. made testwells in 1929 to determine subsurface temperatures. One test hole was abandoned at 265 feet, when the temperature reached 401 °F and the steam pressure threatened to destroy the drilling rig.

The stark, barren landscape of Porcelain Basin is the result of an acidic environment. Because of this hostile condition, plants, algae and bacteria have difficulty establishing themselves. Instead, the basin derives its colors from mineral oxides, in spectrums of pink, red, orange (iron oxides) and yellow (sulfur and iron sulfates). The acidic water also has created changes in the formation of sinter deposited around vents. Silica deposits as tiny, sharp spines instead of thick, beaded deposits common in more alkaline basins.

The Back Basin has the worlds largest geyser, but plays at irregular intervals. Steamboat Geyser has long periods of dormancy, but when it does erupt, it sends jets of water nearly 380 feet high in a spectacular display. Echinus Geyser is the largest predictable geyser at Norris. Before an eruption, water usually fills the basin to within two or three feet of the rim and begins boiling. Churning and splashing then trigger an eruption, throwing water and steam upward in a series of explosive bursts. After an eruption, the basin drains, producing a whirlpool and a gurgling that sounds as if a stopper from a bathtub had been pulled.


Solfatara Creek Trail
Length: 6.1 miles, one way, to Norris Campground.
Elevation change: Trailhead at 7,400 feet (84-foot loss). 
Trailhead: The best entrance for a one-way, downhill hike is to start 13.5 miles south of Mammoth (or 7.1 miles north of Norris Junction). A small, circular parking area on a short service road, east of the highway, marks the trailhead. It is a one-way hike, and a car shuttle is required, but the trail does end at the Norris Campground.

From the start, the trail enters the lodgepole forest; to the south, up a small, steep drainage, is Amphitheater Springs. The trail then wanders directly beneath a powerline for a good third of the hike, but the powerline is visible for most of the duration. The trail illustrates a common concern and a lack of proper trail placement in recent years. In the past few decades, many of the trails have been aligned in the path of powerlines- or, in some cases, powerlines have been erected following traditional trails. The Solfatara Trail is no exception. A 50- to 60-foot-wide swath has been cut out of the forest to allow for potential falling trees to clear the powerlines. The 1988 fires burned along this trail, and gallant fire-fighting efforts to wrap the power poles in aluminum foil saved some, but many burned. After the 1988 fires, the lines were restrung, but many of the powerlines could have been buried and a wiser, esthetic, ecological, and environmental approach could have been pursued. No plan or suggestion was made. It was purely cost and profit that motivated the reconstruction of existing lines and the cutting of swaths through pristine, virgin forest for new connections. The effects of the 1988 fire can be found along this trail. Chain-saw cut, burned trees testify to the widening of the swath to protect the powerline.

After about a mile, Lake-of-the-Woods becomes visible through the burned trees to the northeast. It is possible to bush-whack directly to the lake from the trail, but an easier route is to continue down the trail until it separates from the powerline. A faint game trail then doubles back along the outlet to the lake.

A short distance beyond the stream crossing is a cluster of extinct, dormant, and some active thermal springs, called Whiterock Springs. Most of the area is acidic and barren of vegetation. It resembles a moonscape. In one area is a small algal-bacteria filled lake that bubbles and froths.

The remaining trail wanders through meadows and along Solfatara Creek. The word Solfatara is from an Italian origin that means "a volcanic vent, from which only sulphurous exhalations and aqueous vapours are emitted," and these vents often have a greenish tinge due to the combination of algae. Solfatara Creek is fed by thermal springs, and sulphur-loving bacteria line the stream. During summer, they react to the bright sunlight and become bright green.

Shortly before reaching Norris Campground is a trail junction that leads to Ice Lake (see Ice Lake Trail for description). From the junction, it is only slightly more than a half mile through lodgepole pines to the campground, and the trail emerges in the east central edge.


Artist Paint Pot Trail
(Gibbon Geyser Basin)
Length: 0.75 miles, loop.
Elevation change: Trailhead at 7,355 feet (55-foot gain).
Trailhead: The parking area and trailhead is a wide spot on the road, located 4.1 miles south of Norris Junction.

The Artist Paint Pots are the most popular feature of the Gibbon Geyser Basin. They are isolated in the lodgepole forest at the end of a three-quarter-mile-loop hike. The group was named after the pastel multicolored mud pots. Iron oxides have tinted white siliceous mud various colors of pastel beige, pink and slate. The thickness of the mud varies from season to season. In spring and fall, the mud pots are thin and soupy, and the mud bubbles and boils. By late summer, the mud pots thicken and may hurl hot mud 10 to 15 feet into the air. Mud cones also will form when the mud is thick, only to dissolve into mud pots when excess moisture is present.

The trail then emerges into a desolate geyser basin. Several cylindrical cones dominate the basin. Most are dormant, except Monument Geyser, also called Thermos Bottle. It is a IO-foot-tall cone formed in a thermos bottle shape, with a narrow diameter vent. It is a steady geyser but ejects very little water. It does, however, emit a constant, low hissing sound. Because of its height and age. Monument Geyser is sealing its vent with internal deposits of sinter. Several nearby cones already have sealed their vents and thus have become extinct geysers. Army Park Superintendent P.W. Norris named these features in 1878.
