## Claims

### Claim 1

A method of making a golf bunker, comprising the steps of:
excavating a hole into the ground;
obtaining tiles of a lesser width and tiles of a greater width, wherein the tiles comprise an artificial grass-covered surface;
layering tiles of a lesser width and placing one layer of tile of the greater width on top of the layers of lesser width;
backfilling a volume behind the tiles with cement modified soil;
repeating the steps of layering tiles and backfilling a volume with cement modified soil until a desired bunker wall height is achieved;
covering the top layer of tiles and the top of the cement modified soil with natural soil; and
covering the natural soil with natural turf.
