Snow-fed rivers tumble over granite boulders in the Rocky Mountains, creating an ideal environment for fly-fishing and whitewater rafting. The state's most famous river -- the Colorado -- flows from headwaters in Rocky Mountain National Park, with alternating stretches of heart-pounding hydraulics and quiet areas where you can wade out and cast your fly. Stay at a Bureau of Land Management campground along the shore, or at private riverside cabins such as those found at Colorado Cabin Adventures 3 miles from Grand Lake. For a more remote experience, stay at Cottonwood Cove, tucked along the banks of the Rio Grande just downstream from the picturesque mining town of Creede.
Another historic and romantic hotel in Durango is The Strater Hotel. This hotel was special to our family as my husband’s great-great-aunt aunt actually worked here. A member of the Historic Hotels of America, the Strater is one of those iconic Old West hotels where you literally feel as if you’ve stepped back in time to experience the romance of the Victorian era and the rails of the late 1800s. Located two blocks from the train depot and the General Palmer, you can also watch the train from this hotel.
The landlocked state boasts about four dozen major lakes where you'll find waterside recreation ranging from houseboating to fishing to waterskiing. In the southwest corner of the state, Navajo State Park boasts a 15,000-acre reservoir that extends into the state of New Mexico. Camp in one of 150 campsites, book a night at the Navajo Lodge, or explore the lake for days on a houseboat. Dillon Reservoir near Breckenridge tucks into pine-laden hills near some of the state's most renowned ski areas. Fish the lake for cutthroat trout, brookies or salmon, or take a sailing lesson at the Dillon Marina.
About 300 million years ago, the land was uplifted creating the ancestral Rocky Mountains.[55] Fountain Formation was deposited during the Pennsylvanian period of the Paleozoic era, 290–296 million years ago. Over the next 150 million years, the mountains uplifted, continued to erode, and covered themselves in their own sediment. Wind, gravity, rainwater, snow, and glacial ice eroded the granite mountains over geologic time scales.[56] The Ancestral Rockies were eventually buried under subsequent strata.[57]

The montane ecosystem is at the lowest elevations in the park, between 5,600 to 9,500 feet (1,700 to 2,900 m), where the slopes and large meadow valleys support the widest range of plant and animal life,[69][70] including montane forests, grasslands, and shrublands. The area has meandering rivers[70] and during the summer, wildflowers grow in the open meadows. Ponderosa pine trees, grass, shrubs and herbs live on dry, south-facing slopes. North-facing slopes retain moisture better than those that face south. The soil better supports dense populations of trees, like Douglas fir, lodgepole pine, and ponderosa pine. There are also occasional Engelmann spruce and blue spruce trees. Quaking aspens thrive in high-moisture montane soils. Other water-loving small trees like willows, grey alder, and water birch may be found along streams or lakeshores. Water-logged soil in flat montane valleys may be unable to support growth of evergreen forests.[70] The following areas are part of the montane ecosystem: Moraine Park, Horseshoe Park, Kawuneeche Valley, and Upper Beaver Meadows.[70]

Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4.5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a shallow sea, with a seabed composed of limestone and dolomite deposits many kilometers thick.[54] Pikes Peak granite formed during the late Precambrian eon, continuing well into the Paleozoic era, when mass quantities of molten rock flowed, amalgamated, and formed the continents about 1 billion–300 million years ago. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime and mud sediments were deposited in the vacated space. Eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin.[55]
In winter you can try cross-country skiing and snowmobile trails and after an energetic day out there is nothing better than a soak in one of the natural thermal springs. You can visit the Buena Vista Heritage Museum or go on a Ghost Town adventure, visit several working art studios and galleries, or quench your thirst at a local brewery. Things to Do in Buena Vista
Situated in Southern Colorado, the Great Sand Dunes National Park is an impressive sight. Shaped by winds blowing from and against the nearby Sangre de Cristo Mountains, the piles of sand climb to more than 750 feet (230 meters), making them the tallest dunes in North America. Sand-boarding, skiing and sledding on the dunes are the park’s most popular activities, and there are medium-size slopes to slide on located near the main parking area. A longer hike to the north brings thrill seekers to a 300-foot (90 meter) slope that tumbles onto into Medano Creek.
The park has a total of five visitor centers[9] with park headquarters located at the Beaver Meadows Visitor Center—a National Historic Landmark designed by the Frank Lloyd Wright School of Architecture at Taliesin West.[10] National Forest lands surround the park including Roosevelt National Forest to the north and east, Routt National Forest to the north and west, and Arapaho National Forest to the west and south, with the Indian Peaks Wilderness area located directly south of the park.[5]

From 9,000 ft (2,700 m) to 11,000 ft (3,400 m),[72] the montane forests give way to subalpine forests.[69] Forests of fir and Engelmann spruce cover the mountainsides in subalpine areas. Trees grow straight and tall in the lower subalpine forests, but become shorter and more deformed the nearer they are to the tree line.[72] At the tree line, seedlings may germinate on the lee side of rocks and grow only as high as the rock provides wind protection, with any further growth being more horizontal than vertical. The low growth of dense trees is called krummholz, which may become well-established and live for several hundred to a thousand years old.[72]
