A snow-gun for producing man-made snow from a combination of compressed air and water features a new nozzle configuration for discharging a mixture of water-particles and air into the surrounding atmosphere. Such nozzle is provided with an elliptically-shaped discharge port having a transverse cross-section that gradually expands in size in the direction in which the air and water particles are discharged from said nozzle. Preferably, the area of the elliptical port changes non-linearly through the front wall of the nozzle, whereby water particles exiting the gun through the nozzle port are less likely to collide with the side walls of the port or with each other before reaching the relatively cold ambient atmosphere.

A vehicle for removing an accumulation of particles comprises a vehicle body, a system configured to remove the particles in bulk, and an arm coupled to and extending from the vehicle body. The arm comprises a first sweeping element and a second sweeping element. Each sweeping element includes a shaft member rotatable about a longitudinal axis, and a set of bristles projecting away from the axis along the shaft member. The first and second longitudinal axes are a distance apart, and the sweeping elements define a concerted sweeping area. The arm may be movably coupled to the vehicle body and may be configured to move the sweeping element around the vehicle body by rotating the arm about a horizontal axis. When a sweeping element rotates in proximity to the ground, the longitudinal axis is substantially vertical. The vehicle may further include a computer system for tracking the location of an object.

A snowshoe with binding suspended by tension straps secured to a frame is assembled from a generally U-shaped nose, and an aft section which can be a midsection and a tail. In one embodiment the nose has sufficient strength to resist inward pulling under tension to suspend the binding resiliently, without significant strength contribution from aft portions of the frame. The aft portion of the snowshoe includes traction elements, i.e. rows of teeth, positioned to engage into snow and ice. An important aspect of the invention is that the nose and aft sections are non-integral and very dissimilar in cross section, in a suspended-binding snowshoe.
