Claim:
A modular wall block adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall, said wall block comprising: a front and rear, top and bottom, and opposing sides, said top and bottom defining respective top and bottom substantially planar stacking surfaces; a shear lug projecting from said bottom planar stacking surface; a block-locating jut formed with at least one of said opposing sides, and projecting from said side beginning at a point intermediate said top and bottom, and extending at an outward angle from said side towards said top planar stacking surface; said block-locating jut defined by a plurality of converging planar and substantially triangular surfaces which intersect at an apex spaced apart from said side and proximate said top planar stacking surface; and said block-locating jut further defining a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.
