    Actually, if the snow is too deep, you can't land because the gear will fail. The guys at the Durango FBO were telling me that back in the '80s a Metroliner got a bad snow report (told 1/4th inch when actually 4 inches), when the nosewheel touched down, the force from plowing through the snow caused it to snap off.
    Sounds similar to a CF 5 of the Canadian Forces that made a landing at Westover ARB, MA about 25 years ago on a newly ploughed runway. Great except the operator left a six inch ridge of wet snow, which caused the nosewheel to collapse when the aircraft hit it. Consequences-a badly injured pilot and a written off aircraft.

      There are two real issues with runways, the first is braking action, i.e. how slippy is it, and secondly contamination type / percentage as this will effect acceleration and possibly stopping to. Special performance tables are used, or some airlines have access to computer generated performance figures based on a various data inputs.

      Operated into Kittila way up in northern Finland a few years ago with temps of -30C. The runway was covered in compacted snow. Essentially the landing technique is still the same, however the key is to ensure the performance data is correct. Peripheral vision can be effected if all the ground is white, and their are special techniques for "white out" landings. Air density corrections for altitude correction are important when it is very cold!!!

      Slushy conditions can be the worst as it sticks to everything, gear, flaps etc. and seriously effects takeoff performance, although blowing snow can fuzz out the runway edges.

      Freezing rain will ground us / stop us landing in most cases.
