Bear Lake (Colorado)
Bear Lake is a scenic trailhead and destination in Rocky Mountain National Park. Sitting at an elevation of 9,450 feet, the lake rests beneath the sheer flanks of Hallett Peak. Several trails, from easy strolls to strenuous hikes, start from the lake, the Bear Lake Road is open year-round, though it may temporarily close due to adverse weather conditions. An ample parking lot is provided close to the lake, the Bear Lake Road is approximately 10 miles long and starts close to the Beaver Meadows Entrance station of the Rocky Mountains National Park. The lake was formed during the ice age by a glacier, several moraines can be found downhill of Bear Lake.

It is 16.5 cm long and weighs on average 46 g. It has long legs, and bobs its whole body up and down during pauses as it feeds on the bottom of fast-moving and it inhabits the mountainous regions of Central America and western North America from Panama to Alaska. This species, like other dippers, is equipped with an extra eyelid called a membrane that allows it to see underwater. Dippers produce more oil than most birds, which may keep them warmer when seeking food underwater. In most of its habits, it resembles its European counterpart, the white-throated dipper, Cinclus cinclus. It feeds on insects and their larvae, including dragonfly nymphs, small crayfish. It may take fish or tadpoles. The song consists of high whistles or trills peee peee pijur pijur repeated a few times, both sexes of this bird sing year round. It defends a territory along streams. Its habit of diving underwater in search of food can make it the prey of large salmonids like bull or Dolly Varden trout. The American dippers nest is a structure with a side entrance, close to water, on a rock ledge, river bank.
The normal clutch is 2-4 white eggs, incubated solely by the female, the male helps to feed the young. It is usually a permanent resident, moving slightly south or to lower elevations if necessary to find food or unfrozen water, the presence of this indicator species shows good water quality, it has vanished from some locations due to pollution or increased silt load in streams.

Colorado is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Western United States, the Southwestern United States, Colorado is the 8th most extensive and the 21st most populous of the 50 United States. The United States Census Bureau estimates that the population of Colorado was 5,540,545 on July 1,2016, the state was named for the Colorado River, which Spanish travelers named the Río Colorado for the ruddy silt the river carried from the mountains. The Territory of Colorado was organized on February 28,1861, Colorado is nicknamed the Centennial State because it became a state in the same year as the centennial of the United States Declaration of Independence. Colorado is noted for its landscape of mountains, high plains, canyons, rivers. Denver is the capital and the most populous city of Colorado, residents of the state are properly known as Coloradans, although the term Coloradoan has been used archaically and lives on in the title of Fort Collins newspaper, the Coloradoan.
Colorado and Utah are the states which have boundaries defined solely by lines of latitude and longitude. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado, Colorado is the only U. S. state that lies entirely above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County and this point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia. A little less than one half of the area of Colorado is flat, East of the Rocky Mountains are the Colorado Eastern Plains of the High Plains, the section of the Great Plains within Nebraska at elevations ranging from roughly 3,350 to 7,500 feet. The Colorado plains were mostly prairies, but they have many patches of forests, buttes. Eastern Colorado is presently covered in farmland and rangeland, along with small farming villages. Precipitation is fair, averaging from 15 to 25 inches annually, wheat, hay and oats are all typical crops, and most of the villages and towns in this region boast both a water tower and a grain elevator.
Irrigation water is available from the South Platte, the Arkansas River, and a few other streams, heavy use of ground water from wells for irrigation has caused underground water reserves to decline. As well as agriculture, eastern Colorado hosts considerable livestock, such as cattle ranches. Roughly 70% of Colorados population resides along the edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne and Pueblo, Colorado. This region is protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado. The Front Range includes Denver, Fort Collins, Colorado Springs, Pueblo and other townships, on the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction and Montrose
Milner Pass, elevation 10,759 ft is a mountain pass in the Rocky Mountains of northern Colorado in the United States. It is located on the divide in the Front Range, within Rocky Mountain National Park. The pass provides the passage over the continental divide for US34, the pass is not, the high point on Trail Ridge Road, which crests at 12,183 ft east of the pass within Rocky Mountain National Park. Along with the rest of Trail Ridge Road, the pass is closed in winter from the first heavy snow fall until the opening of the road around Memorial Day. The gentle pass divides the headwaters of the Cache la Poudre River, the road near the pass provides a panoramic view of the Never Summer Mountains to the west
St. Vrain Creek
St. Vrain Creek is a tributary of the South Platte River, approximately 32.2 miles long, in north central Colorado in the United States. It drains part of the north of Boulder and the Colorado Piedmont area in the vicinity of Longmont. The creek is formed by the confluence of North and South St. Vrain creeks at Lyons, the creek rises in several branches in the foothills of the Front Range northwest of Boulder. Middle St. Vrain Creek rises along the divide, west of St. Vrain Mountain. It descends in canyon to flow along State Highway 7 and past Raymond and it joins the shorter South St. Vrain Creek about two miles below Raymond. South St. Vrain Creek at flood stage is a five mile Class 5+ kayak run at flood stage, North St. Vrain Creek rises northeast of St. Vrain Mountain near Allenspark and descends in a remote canyon to the east along U. S. Highway 36. The two branches join at Lyons, at the mouth of the canyon, east of Lyons, the combined stream flows southeast through farmland and ranch country, passing south of Hygiene and entering Longmont.
It passes through the side of Longmont where it is rimmed by a greenway trail. East of Longmont it flows generally northeast, meandering through a river bottom in ranch country. It joins the South Platte from the west just upstream from the ruins of Fort St. Vrain, St. Vrain Creek is joined by Left Hand Creek south of Longmont and Boulder Creek east of Longmont. The stream was named after Ceran St. Vrain, a pioneer trader
Agnes Vaille Shelter
The Agnes Vaille Shelter is a beehive-shaped stone shelter near the summit of Longs Peak in Rocky Mountain National Park, Colorado, USA. The shelter was built in 1927 by the National Park Service after a number of climbers died ascending Longs Peak, the shelter was named for Agnes Vaille, who made the first winter ascent of the east face of Longs Peak by a woman. On January 12,1925, Vaille fell 100 ft while descending the North Face, Vaille survived the fall with minor injuries, but was unable to walk. Her climbing partner, professional mountaineering guide Walter Kiener, went for help, one of the rescuers, Herbert Sortland, froze to death after breaking his hip while trying to rescue her. The stone for the shelter came from this area, the shelter consists of a single circular room with a conical ceiling formed by the walls and roof of the shelter, entered by a single door opening whose door has been removed. As a result, the interior may be filled with snow for much of summer. There are two glazed windows and one opening, and the floor is paved with stone.
Recent scholarship asserts that the present shelter was built by Vailles family in 1935 to replace the 1927 Park Service shelter, the Agnes Vaille Shelter was listed on the National Register of Historic Places on December 24,1992
Rocky Mountain National Park
The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and westerns slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the northwestern region. The main features of the park include mountains, alpine lakes, the Rocky Mountain National Park Act was signed by then–President Woodrow Wilson on January 26,1915, establishing the park boundaries and protecting the area for future generations. The Civilian Conservation Corps built the main route, named Trail Ridge Road. In 1976, UNESCO designated the park as one of the first World Biosphere Reserves, in 2016, more than four and a half million recreational visitors entered the park, which is an increase of about nine percent from the prior year. The history of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt and Arapaho people subsequently hunted and camped in the area.
In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River. Settlers began arriving in the mid-1800s, displacing the Native Americans who mostly left the area voluntarily by 1860, lulu City and Gaskill in the Never Summer Mountains were established in the 1870s when prospectors came in search of gold and silver. The boom ended by 1883 with miners deserting their claims, the railroad reached Lyons, Colorado in 1881 and the Big Thompson Canyon Road—a section of U. S. Route 34 from Loveland to Estes Park—was completed in 1904. The 1920s saw a boom in building lodges and roads in the park, prominent individuals in the effort to create a national park included Enos Mills from the Estes Park area, James Grafton Rogers from Denver, and J. Horace McFarland of Pennsylvania. The national park was established on January 26,1915, 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 sea, with a seabed composed of limestone. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime, eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin. About 300 million years ago, the land was uplifted creating the ancestral Rocky Mountains, fountain Formation was deposited during the Pennsylvanian period of the Paleozoic era, 290–296 million years ago. Over the next 150 million years, the uplifted, continued to erode. Wind, rainwater and glacial ice eroded the mountains over geologic time scales. The Ancestral Rockies were eventually buried under subsequent strata, the Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed
Hallett Peak is a mountain summit in the northern Front Range of the Rocky Mountains of North America. Hallett Peak is on the Continental Divide, flanked by Flattop Mountain to the north, just to its east lie Emerald Lake, Dream Lake, and Nymph Lake, which are usually accessed from the Bear Lake Comfort Station. The Northcutt-Carter Route of Hallett Peak is recognized in the historic climbing text Fifty Classic Climbs of North America. Non-technical climbers may reach the summit of Hallett Peak by hiking up the Flattop Mountain Trail to its highpoint, walking south along the ridgeline and ascending the peak over talus piles
