Snowmobile in the context of "Passengers"

Alpine skiing, or downhill skiing, is the pastime of sliding down snow-covered slopes on skis with fixed-heel bindings, unlike other types of skiing (cross-country, Telemark, or ski jumping), which use skis with free-heel bindings. Whether for recreation or for sport, it is typically practiced at ski resorts, which provide such services as ski lifts, artificial snow making, snow grooming, restaurants, and ski patrol.

"Off-piste" skiers—those skiing outside ski area boundaries—may employ snowmobiles, helicopters or snowcats to deliver them to the top of a slope. Back-country skiers may use specialized equipment with a free-heel mode, including 'sticky' skins on the bottoms of the skis to stop them sliding backwards during an ascent, then locking the heel and removing the skins for their descent.

Google Street View is a technology featured in Google Maps and Google Earth that provides interactive panoramas from positions along many streets in the world. Google Street View displays interactive panoramas of stitched VR photographs. Most photography is done by car, but some is done by tricycle, camel, boat, snowmobile, underwater apparatus, and on foot.

First launched in 2007 in several cities in the United States, Street View has since expanded to include all of the country's major and minor cities, as well as the cities and rural areas of many other countries worldwide. As of 2017, Street View had coverage in 83 countries. Street View has been used for research in fields like urban analytics and geographic information science. Street View imagery has also been used in artistic work.

Denali National Park and Preserve, formerly known as Mount McKinley National Park, is a United States national park and preserve located in Interior Alaska, centered on Denali (federally designated as Mount McKinley), the highest mountain in North America. The park and contiguous preserve encompass 6,045,153 acres (2,446,387 ha; 9,446 sq mi; 24,464 km) which is larger than the state of New Hampshire. On December 2, 1980, 2,146,580-acre (3,354 sq mi; 8,687 km) Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, and snowmobiling. The park received 594,660 recreational visitors in 2018.

A sled dog is a dog trained and used to pull a land vehicle in harness, most commonly a sled over snow.

Sled dogs have been used in the Arctic for at least 8,000 years and, along with watercraft, were the only transportation in Arctic areas until the introduction of semi-trailer trucks, snowmobiles and airplanes in the 20th century, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both poles, as well as during the Alaskan gold rush. Sled dog teams delivered mail to rural communities in Alaska, Yukon, Northwest Territories and Nunavut. Sled dogs today are still used by some rural communities, especially in areas of Russia, Canada, and Alaska as well as much of Greenland. They are used for recreational purposes and racing events, such as the Iditarod Trail and the Yukon Quest.

A passenger is a person who travels in a vehicle, but does not bear any responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle, and is not a steward. The vehicles may be bicycles, buses, cars, passenger trains, airliners, ships, ferryboats, personal watercraft, all terrain vehicles, snowmobiles, and other methods of transportation.

Crew members (if any), as well as the driver or pilot of the vehicle, are usually not considered to be passengers. For example, a flight attendant on an airline would not be considered a passenger while on duty and the same with those working in the kitchen or restaurant on board a ship as well as cleaning staff, but an employee riding in a company car being driven by another person would be considered a passenger, even if the car was being driven on company business.

The Wankel engine (/ˈvʌŋkəl/, VAHN-kəl) is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor spins inside a figure-eight-like epitrochoidal housing around a fixed gear. The midpoint of the rotor moves in a circle around the output shaft, rotating the shaft via a cam.

In its basic gasoline-fuelled form, the Wankel engine has lower thermal efficiency and higher exhaust emissions relative to the four-stroke reciprocating engine. This thermal inefficiency has restricted the Wankel engine to limited use since its introduction in the 1960s. However, many disadvantages have mainly been overcome over the succeeding decades following the development and production of road-going vehicles. The advantages of compact design, smoothness, lower weight, and fewer parts over reciprocating internal combustion engines make Wankel engines suited for applications such as chainsaws, auxiliary power units (APUs), loitering munitions, aircraft, personal watercraft, snowmobiles, motorcycles, racing cars, and automotive range extenders.

Snow grooming is the process of manipulating snow for recreational uses with a tractor, snowmobile, piste caterpillar, truck or snowcat towing specialized equipment. The process is used to maintain ski hills, cross-country ski trails and snowmobile trails by grooming (moving, flattening, rototilling, or compacting) the snow on them. A variation of the technique is used to construct snow runways in Antarctica.

A snow groomer is usually employed to pack snow and improve skiing and snowboarding and snowmobile trail conditions. The resulting pattern on the snow is known as corduroy, and is widely regarded as a good surface on which to ski or ride. Snow groomers can also move accumulated snow made by snow machines as part of a process, called "snow farming".

Ski patrols are organizations that provide medical, rescue, and hazard prevention services to the injured in ski area boundaries, or sometimes beyond into backcountry settings. Many have technical-medical certifications, such as Outdoor Emergency Care (OEC) provided by the National Ski Patrol (USA), that are specific to the winter-season environment and providing emergency medical services in remote locations. Many patrollers also hold EMS issued credentials, such as emergency medical technician or any other pre-hospital care certification. Due to the remote location and terrain, transportation is often limited to Rescue toboggan, snowmobile, or, for life-compromising injuries or extremely remote terrain, helicopter rescue. Depending on the ski area terrain, ski patrollers can be versed in a large variety of specialized rescues, such as avalanche search and rescue, outdoor emergency transportation, chairlift evacuation, and, in some cases, helicopter rescue techniques are taught. Patrols work to promote ski safety, enforce area policies (where applicable), and help the injured within their jurisdiction. Ski patrollers also work to set up the mountain before it opens by conducting trail checks, providing avalanche control work, and setting up necessary equipment in preparation for the day. At the end of the day, they also conduct a sweep clearing the mountain for off-hours.

Contrary to the name's implications, ski patrollers can be snowboarders in addition to alpine, Nordic, or telemark skiers. Many patrols also have non-skiing positions whereby patrollers no longer able to ski or individuals lacking sufficient skiing or toboggan handling skills can still provide emergency care in a first aid room. Some ski areas also have a junior ski patrol program in which teenagers between the ages of 15 and 17 years old can participate. Most junior ski patrol programs limit the responsibilities of their members, such as preventing them from running toboggans or administering first aid without supervision. However, there are some areas with junior ski patrol programs which allow their members to operate with the same responsibilities as the rest of the patrol, after meeting the same standard in each skill category as other patrollers.
