Argos are supposed to be amphibious – this one wasn’t!


An amphibious vehicle (or simply amphibian) is a vehicle that can travel on land as well as on or under water. Amphibious bicycles, ATVs, cars, buses, trucks, railway vehicles, combat vehicles, and hovercraft are examples of amphibious vehicles.

Sea to Sky

There are two types of amphibious vehicles: those that travel on an air cushion (Hovercraft) and those that do not. Many of the latter were inspired by the desire to expand the off-road capabilities of land vehicles to a “all-terrain” capability, with some designs focusing not only on creating a transport that will work on land and water, but also on intermediates such as ice, snow, mud, marsh, swamp, and so on. This explains why many designs use tracks in addition to or instead of wheels, and why some designs, such as screw-propelled vehicles, use auger-like barrels to propel a vehicle through muddy terrain with a twisting motion.

Most land vehicles, even those with light armour, can be made amphibious simply by adding a waterproof hull and possibly a propeller. This is possible because the displacement of a vehicle is usually greater than its weight, causing it to float. Heavily armoured vehicles, on the other hand, have a density greater than water (their weight in kilograms exceeds their volume in litres), necessitating the use of additional buoyancy measures. These can be inflatable floatation devices, similar to the sides of a rubber dinghy, or a waterproof fabric skirt raised from the vehicle’s top perimeter to increase displacement.

Some of the earliest known amphibious vehicles were amphibious carriages, which were invented in July 1770 or earlier by the Neapolitan polymath Prince Raimondo di Sangro of Sansevero or Samuel Bentham, whose design of 1781 was built in June 1787.

The conestoga wagon, a heavy covered wagon, was popular in the United States and Canada during the 18th and 19th centuries. The wagon was built in such a way that it could cross rivers and streams.

Reid Lake

Reid Lake, 61 kilometres from Yellowknife, offers swimming, canoeing, and fishing. There is a beach, boat ramp, and walking trail at the campground, as well as campsites on the ridge with great lake views. From May to September, Reid Lake Campground provides RV camping. The campground has 65 gravel RV camping spots with no hookups. Hikers can explore the park’s lakeshore and forests, as well as connect to nearby hiking trails. The area is well-known for its spectacular views of the aurora borealis at night.
