Overview

The Snowy Range is the dramatic, quartzite-capped alpine crest of Wyoming’s Medicine Bow Mountains — a compact but spectacular high-country zone in the Medicine Bow National Forest west of Laramie where 2.5-billion-year-old Snowy Range Quartzite has been thrust upward, glacially sculpted, and exposed to create one of the most visually striking alpine landscapes in southern Wyoming. From the Laramie Basin and the Great Plains to the east, the Snowy Range’s brilliant white quartzite outcroppings glow on the Medicine Bow Mountains horizon like permanent snowfields, giving the range its evocative name.

The Snowy Range Scenic Byway (Wyoming Highway 130) is the defining access — one of Wyoming’s finest alpine drives, the road climbs from Laramie’s 7,165-foot elevation over a 10,847-foot pass near Lake Marie (immediately below the 12,013-foot summit of Medicine Bow Peak), providing access to the alpine zone that few Rocky Mountain scenic drives can rival. Along the way, the byway passes a remarkable chain of glacial lakes — Lake Marie, Mirror Lake, Lake Libby, and others — each reflecting the brilliant white quartzite formations above. For hikers, the Medicine Bow Peak summit hike from Lake Marie is southern Wyoming’s finest alpine summit; for anglers, the Snowy Range lakes hold wild cutthroat and brook trout; for skiers, the Snowy Range Ski Area operates on the byway’s west slope. Compact, accessible, and visually extraordinary, the Snowy Range is one of Wyoming’s most beloved and rewarding alpine destinations.

Recreation

The Snowy Range offers hiking — the Medicine Bow Peak summit hike (5 miles round trip from the Lake Marie trailhead, 1,300 feet of elevation gain across open quartzite ridge and talus to the 12,013-foot summit; southern Wyoming’s finest alpine summit hike with a 360-degree panoramic view of the Laramie Basin, the Great Plains, and the Wyoming Range), the Lake Marie and Mirror Lake short walks (1-3 miles; easy to moderate; the lake reflections and quartzite formations are among the finest photographic subjects in southern Wyoming), the Sugarloaf Mountain Trail (a moderate ridge hike past the byway’s most dramatic quartzite formations), and the Laramie River drainage trails (creek fishing and riparian hiking on the west slope below the byway). Fishing in the Snowy Range lakes (Lake Marie, Mirror Lake, Lake Libby, and the smaller unnamed alpine lakes; cutthroat and brook trout; fly-fishing with dry flies on calm morning water is highly productive; Wyoming fishing license required) is excellent. The Snowy Range Scenic Byway drive (a 65-mile round trip from Laramie over the nearly 11,000-foot pass to Saratoga; open Memorial Day through late October; one of Wyoming’s finest alpine scenic drives) is the most broadly accessible experience. Snowy Range Ski Area (adjacent to the byway on the west slope) offers alpine skiing from late November through early April. Cross-country skiing and snowshoeing on the closed byway corridor are premier winter activities. Photography of the quartzite formations, the glacial lakes, and the alpine wildflowers (peak mid-July) is one of the finest photographic experiences in southern Wyoming. The byway drive, the Medicine Bow Peak summit, and the lake reflections are the signature draws.

Best Time to Visit

The Snowy Range Scenic Byway (WY-130) is open from Memorial Day weekend (late May) through late October; access outside this window requires skiing, snowshoeing, or high-clearance four-wheel drive on unpaved winter roads. The finest hiking and lake-photography season is mid-July through mid-September. By mid-July the quartzite ridge is typically snow-free, the alpine wildflowers (sky pilot, alpine forget-me-not, alpine avens) are at peak bloom in the bowl below Medicine Bow Peak, and the lakes are fully ice-free and at their most beautiful — the mirror-still reflections of the quartzite formations at dawn are extraordinary. Afternoon thunderstorms are the primary summer hazard; start all alpine activity by 6 AM and be off exposed terrain by noon. Fall (mid-September through mid-October) is the finest overall season — aspen gold in the valley drainages below the byway, crystal-clear air with the longest summit views, the trout feeding actively in the cooling lakes, and a fraction of the summer crowds. Winter at the Snowy Range offers world-class powder snow at the ski area and sublime cross-country skiing on the closed byway corridor; the snow-covered quartzite formations and the deep silence of the winter alpine zone are among Wyoming’s most beautiful winter landscapes.

History

The Snowy Range and the Medicine Bow Mountains take their name from the Arapaho peoples’ term for the mountains as a gathering and trade place for bow-making wood — the straight-grained, dense timber of the mountain forests was prized for making the powerful composite bows of the plains, and the Medicine Bow Mountains were a recognized trade locale for this raw material among the Plains peoples. The Union Pacific Transcontinental Railroad (completed 1869) passed through the Laramie Basin at the Snowy Range’s eastern foot, with the railroad’s demand for timber fueling the first systematic logging of the Medicine Bow forests. The Medicine Bow Forest Reserve was established in 1902; the Snowy Range Scenic Byway was developed as an automobile road in the 1920s by the Civilian Conservation Corps and the Forest Service, opening the alpine terrain to general visitation. The Snowy Range Ski Area was established in the 1960s and has operated as a family-oriented alpine-skiing destination ever since. The quartzite formations of the Snowy Range have been a subject of geological study and public interpretation for over a century — the white quartzite visible from 50 miles away is one of Wyoming’s most instantly recognizable geological landmarks.

Geology

The Snowy Range’s defining geological feature is the Snowy Range Quartzite — a Precambrian metamorphic rock approximately 2.5-to-2.7-billion-years old, originally deposited as a quartz-rich beach sand in an ancient Precambrian sea and subsequently metamorphosed to the hard, white-to-pale-pink quartzite that caps the Medicine Bow Mountains crest. The quartzite is among the oldest exposed rock sequences in Wyoming and one of the most resistant to erosion in the entire Rocky Mountain West — its hardness is the reason the Snowy Range crest stands dramatically above the surrounding forest while the underlying Precambrian gneiss and schist have been eroded to lower elevations. The brilliant white color of the quartzite outcroppings (pure quartz with minimal iron oxide contamination) creates the characteristic “snowy” appearance that the range is named for. The glacial landscape of the Snowy Range — the cirque lakes (Lake Marie, Mirror Lake, and the others are all glacially carved lake basins in the quartzite), the polished quartzite ridges, and the moraines at the lower lake margins — was carved during the Pleistocene glaciations and represents one of the finest accessible glacial landscapes in southern Wyoming.

Wildlife

The Snowy Range’s alpine and subalpine habitats support a distinctive high-country wildlife community. American pika are abundant in the quartzite boulder fields above timberline — their high-pitched barks are among the defining sounds of the Snowy Range, and they are visible throughout the summer at the boulder fields on the Medicine Bow Peak approach. Yellow-bellied marmots sun on the quartzite outcroppings. White-tailed ptarmigan (the all-white alpine grouse) inhabit the alpine tundra and are camouflaged against the quartzite in summer’s patchy snow. Moose are abundant in the willow meadows and beaver-pond complexes of the Medicine Bow River drainage on the byway’s west slope — moose are frequently visible from the byway’s west-slope pullouts and are one of the Snowy Range’s signature wildlife encounters. Elk inhabit the subalpine meadows below the quartzite crest; the fall rut brings bugling to the Snowy Range in September. Clark’s nutcrackers, Steller’s jays, and mountain bluebirds are the most visible birds of the subalpine forest. Cutthroat and brook trout inhabit the Snowy Range lakes.

Ecology

The Snowy Range encompasses some of Wyoming’s most fragile and scientifically significant alpine and subalpine ecosystems. The alpine tundra above timberline (approximately 10,500 feet on the Snowy Range) is a fell-field community of cushion plants, sedge tussocks, and low-growing wildflowers that have evolved to survive the extreme growing conditions of the summit zone — intense ultraviolet radiation, desiccating winds, a growing season of 6-to-8 weeks, and annual temperatures averaging below freezing. These cushion plants grow approximately 1 millimeter per year and are irreparably damaged by a single footfall off the designated trail; staying on the quartzite trail above timberline is an ecological imperative. The Snowy Range lakes are oligotrophic (nutrient-poor) high-alpine water bodies in pristine condition, providing water to the Laramie and Medicine Bow rivers. The treeline ecotone — the krummholz belt of wind-sculpted Engelmann spruce and subalpine fir at the forest-tundra transition — is an active indicator of climate change, with treeline advancing upslope in response to warming temperatures.

Cultural Significance

The Snowy Range holds a special place in the outdoor culture of southeastern Wyoming and the broader Rocky Mountain region as an unusually accessible high-alpine landscape — the Snowy Range Scenic Byway crests at nearly 11,000 feet, putting visitors in the alpine zone without leaving their vehicles and providing a level of high-mountain access rare in the Rocky Mountain West. For Laramie residents and the University of Wyoming community, the Snowy Range is the backyard wilderness and the defining outdoor experience of southern Wyoming. The quartzite formations, the glacial lakes, and the byway drive have been celebrated in Wyoming travel writing for over a century. Owen Wister, who set “The Virginian” in the Medicine Bow country, was inspired by the broader landscape of which the Snowy Range is the alpine crown. The Snowy Range is Wyoming’s most accessible and most photographed alpine landscape outside of the Grand Tetons — a democratic high-mountain experience that requires no technical skill, no wilderness permit, and no long approach.

Access and Directions

The Snowy Range is accessed via the Snowy Range Scenic Byway (Wyoming Highway 130). From Laramie: drive west on WY-130 approximately 35 miles to the Medicine Bow National Forest boundary, and 45 miles to the Snowy Range Pass area and Lake Marie trailhead. The byway is typically open from Memorial Day weekend (late May) through late October; closing dates vary with snowfall — check Wyoming DOT or the Medicine Bow-Routt National Forest for current byway status. Laramie (45 miles east via WY-130) has full services. The Snowy Range Ski Area is 4 miles west of the pass on WY-130. Multiple developed Forest Service campgrounds are available on the byway corridor. A trailhead fee or America the Beautiful Pass may be required at developed trailheads. Saratoga (30 miles west of the pass, via WY-130 and WY-130 spur) has full resort services and the free Hobo Hot Springs.

Conservation

The Medicine Bow-Routt National Forest manages the Snowy Range. The alpine tundra above timberline is the most ecologically fragile zone — stay on the designated quartzite trail at all times above treeline (cushion plants grow 1 millimeter per year and are destroyed by a single footfall). The Snowy Range lakes are pristine high-alpine water bodies; no soap or detergents in or near any lake; camp and wash 200+ feet from all water sources. Fishing in the Snowy Range lakes requires a Wyoming fishing license. The treeline krummholz is a fragile transition zone — do not break or collect any krummholz wood. Follow all Medicine Bow NF fire restrictions (check current restrictions before building any campfire). Leave No Trace principles are required on all trails. Report any unauthorized off-road vehicle use, which destroys the fragile subalpine and alpine soils.

Safety

Afternoon lightning is the Snowy Range’s most serious hazard — the quartzite crests attract intense afternoon thunderstorms virtually every summer day from July through August; start all alpine hikes before 6 AM and be below treeline before noon. The quartzite ridge above timberline can be extremely slippery when wet (wet quartzite polish approaches ice in slipperiness); wear boots with aggressive tread and postpone the Medicine Bow Peak hike if rain is forecast. Altitude: the byway passes crests nearly 11,000 feet and the Medicine Bow Peak summit is 12,013 feet; acclimatize in Laramie (7,165 feet) for at least one full day before any significant elevation gain. The byway can be closed without notice by early or late-season snowstorms; check current road status before any visit from late September through June. Black bears are present in the national forest; store food properly in campgrounds.

Regulations

USFS trailhead fee or America the Beautiful Pass may be required (check Medicine Bow-Routt NF for current fees). Stay on designated trail above timberline. Wyoming fishing license required for all fishing. No camping within 200 feet of any water source or trail. Campfire restrictions apply — check current USFS fire restrictions. No motorized vehicles on hiking trails. Pets on leash in campgrounds and day-use areas. Snowy Range Ski Area has its own lift-ticket and facility fees. The Snowy Range Scenic Byway is closed in winter (typically November through Memorial Day weekend); check USFS or WYDOT for current byway status before any shoulder-season visit.

Nearby Attractions

Laramie, Wyoming (45 miles east — University of Wyoming, Wyoming Territorial Prison State Historic Site, and the city’s lively college-town character), Saratoga (30 miles west via WY-130 spur — the free Hobo Hot Springs on the North Platte, world-class brown-trout fly-fishing, and the resort character of Wyoming’s finest hot-spring town), Snowy Range Ski Area (4 miles west of the pass — family-oriented alpine skiing within the national forest), Vedauwoo (35 miles northeast of Laramie via I-80 — the Sherman Granite climbing area in the Laramie Mountains), Medicine Bow National Forest (the broader public-land context that encompasses the Snowy Range as its most dramatic and accessible alpine zone), and the North Platte River (fly-fishing waters below Saratoga) define the region. The Snowy Range is the alpine heart and the defining scenic icon of southern Wyoming’s outdoor landscape.

Tips

Drive the Snowy Range Scenic Byway from Laramie at dawn to reach Lake Marie for the mirror-still morning reflection of the quartzite formations — the image of the white crests reflected in the glassy alpine lake in the first light is among the most reproducible great photographs in Wyoming; bring a wide-angle lens and a tripod. After the lake, walk the Medicine Bow Peak summit trail (5 miles round trip, starting before 7 AM to be off the summit ridge before noon) for the finest alpine summit view in southern Wyoming — the 360-degree panorama on a clear September morning, with the Great Plains glowing to the east and the Wyoming Range to the west, is one of the finest long views in the entire state. End the drive at Saratoga’s free Hobo Hot Springs — the natural mineral-spring soak on the bank of the North Platte River, with the Snowy Range visible on the horizon, is the perfect close to a Snowy Range day. Visit in mid-September for golden aspens, no mosquitoes, and crystal-clear skies.
