Wall block system

A wall block comprising:

• a front surface and an opposing rear surface extending lengthwise of the block;
• first and second opposing, parallel side surfaces extending between respective ends of the front and rear surfaces, wherein the front and rear surfaces are longer than the first and second side surfaces;
• and
• wherein the rear surface is formed with three trapezoidal shaped slots configured to receive projections of adjacent blocks in a wall.

A wall comprising:

• at least a first course, the first course comprising:
• a plurality of face blocks arranged in side-by-side relationship with each other and forming a first row of the first course;
• and
• a plurality of trunk blocks arranged in side-by-side relationship with each other and forming a second row of the first course, wherein the second row is arranged behind the first row, and wherein a selected trunk block in the second row interconnects two adjacent face blocks in the first row.

A block assembly comprising:

• a trunk block comprising:
• first and second opposing, parallel side walls extending lengthwise of the trunk block and first and second opposing, parallel end walls extending between respective ends of the side walls of the trunk block, wherein the first and second side walls of the trunk block are longer than the first and second end walls of the trunk block;
• and
• at least one trapezoidal shaped projection extending outwardly from the first side wall of the trunk block and at least one trapezoidal shaped slot formed in the first end wall of the trunk block;
• and
• a face block comprising:
• front and rear surfaces extending lengthwise of the face block and first and second side surfaces extending between respective ends of the front and rear surfaces of the face block, wherein the front and rear surfaces of the face block are longer than the first and second side surfaces of the face block, and wherein the rear surface of the face block is formed with at least one trapezoidal shaped slot configured to receive a projection of the trunk block.
