His most recent pieces are inspired by geometry, in the form of natural fractals.
Beck, an engineer with a degree from Oxford who works as a map-maker and orienteer when he's not out tramping through the snow, first plots out his designs on a computer.
The artworks cover a huge area, sometimes up to the size of six football fields.
Each piece takes hours upon hours of heavy-duty physical work and requires an enormous amount of concentration and stamina to complete.
Beck has just published a book with over 200 photos of his winter art.
