San Juan Mountains in the context of "Caldera"

A hike is a long, vigorous walk, usually on trails or footpaths in the countryside. Walking for pleasure developed in Europe during the eighteenth century. Long hikes as part of a religious pilgrimage have existed for a much longer time. "Hiking" is the preferred term in Canada and the United States; the term "walking" is used in these regions for shorter, particularly urban walks. In the United Kingdom and Ireland, the word "walking" describes all forms of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling, hillwalking, and fell walking (a term mostly used for hillwalking in northern England). The term bushwalking is endemic to Australia, having been adopted by the Sydney Bush Walkers Club in 1927. In New Zealand a long, vigorous walk or hike is called tramping. It is a popular activity with numerous hiking organizations worldwide, and studies suggest that all forms of walking have health benefits.

The La Plata Mountains are a small subrange of the San Juan Mountains in the southwestern part of Colorado, United States. They are located on the border between Montezuma and La Plata counties, about 12 miles (19 km) northwest of Durango. Their name is Spanish for silver.

The peaks of the range are easily visible from U.S. Route 160, which skirts the range on the south. The La Plata River and the Mancos River have their headwaters in the range. The Colorado Trail accesses even towards the northern peaks.

A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. Stratovolcanoes can also form a large caldera that gets filled in by a lava dome, or else multiple small cinder cones, lava domes and craters may develop on the caldera's rim.

Although a comparatively unusual type of volcano, they are widespread in the world and in geologic history. Metamorphosed ash flow tuffs are widespread in the Precambrian rocks of northern New Mexico, which indicates that caldera complexes have been important for much of Earth's history. Yellowstone National Park is on three partly covered caldera complexes. The Long Valley Caldera in eastern California is also a complex volcano; the San Juan Mountains in southwestern Colorado are formed on a group of Neogene-age caldera complexes, and most of the Mesozoic and Cenozoic rocks of Nevada, Idaho, and eastern California are also caldera complexes and their erupted ash flow tuffs. The Bennett Lake Caldera in British Columbia and the Yukon Territory is another example of a Cenozoic (Eocene) caldera complex.

Lake City is a statutory town that is the county seat of, the most populous community in, and the only incorporated municipality in Hinsdale County, Colorado, United States. The population was 432 at the 2020 census. It is located in the San Juan Mountains in a valley formed by the convergence of Henson Creek and the headwaters of the Lake Fork of the Gunnison River about seven miles (11 km) east of Uncompahgre Peak, a Colorado fourteener.Lake City is named after nearby Lake San Cristobal.This area lies at the southern end of the Colorado Mineral Belt and when rich mineral deposits were discovered the native population was pushed from their tribal lands and the town of Lake City was incorporated in 1873.

Silverton is a statutory town that is the county seat of, the most populous community in, and the only incorporated municipality in San Juan County, Colorado, United States. The town is located in a remote part of the western San Juan Mountains, a range of the Rocky Mountains. The first mining claims were made in mountains above the Silverton in 1860, near the end of the Colorado Gold Rush and when the land was still controlled by the Utes. Silverton was established shortly after the Utes ceded the region in the 1873 Brunot Agreement, and the town boomed from silver mining until the Panic of 1893 led to a collapse of the silver market, and boomed again from gold mining until the recession caused by the Panic of 1907. The entire town is included as a federally designated National Historic Landmark District, the Silverton Historic District.

Originally called "Bakers Park", Silverton sits in a flat area of the Animas River valley and is surrounded by steep peaks. Most of the peaks surrounding Silverton are thirteeners. The highest being Storm Peak, at 13,487 feet. The town is less than 15 miles from 7 of Colorado's 53 fourteeners, and is known as one of the premier gateways into the Colorado backcountry.

Telluride is the county seat of and the most populous town in San Miguel County in the southwestern portion of the U.S. state of Colorado. The town is a former silver mining camp on the San Miguel River in the western San Juan Mountains. The first gold mining claim was made in the mountains above Telluride in 1875, and early settlement of what is now Telluride followed. The town was founded in 1878.

Telluride sits in a box canyon. Steep forested mountains and cliffs surround it, with Bridal Veil Falls situated at the canyon's head. Numerous weathered ruins of old mining operations dot the hillsides. A free gondola connects the town with its companion town, Mountain Village, at the base of the ski area. Telluride and the surrounding area have featured prominently in popular culture, and it is the subject of several popular songs. It is especially known for its ski resort and slopes during the winter, as well as an extensive festival schedule during the summer, including the Hot Air Balloon Festival, which traditionally occurs the first weekend in June.

The Idarado Mine was a mining operation in the San Juan Mountains of Ouray County, Colorado near the now-ghost town of Guston, producing primarily lead, zinc and silver along with small amounts of gold and copper. The mine is within the Sneffels-Red Mountain-Telluride mining district. The remains of the operation are visible from the Million Dollar Highway, north of Red Mountain Pass, between Ouray and Silverton, Colorado. The tunnels of the Idarado extend some 5 miles (8 km) west under 13,000 foot (4,000 m) mountains to the Pandora Mill near Telluride, a trip of more than 60 miles (100 km) by highway.

Red Mountain Pass elevation 11,018 ft (3,358 m) is a mountain pass in the San Juan Mountains of western Coloradoin the United States.

The pass straddles a divide that separates Ouray and San Juan counties. The pass is named for the nearby Red Mountain on the northeast side of the pass. The name is derived from the iron oxide laden rock that forms their slopes.
