A retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

1. A retaining wall comprising a plurality of courses of retaining wall blocks including a first upper course and an adjacent second lower course, each retaining wall block having opposed front and rear faces, the rear face having at least a first surface and a second surface, opposed first and second side surfaces, an upper surface opposed and substantially parallel to a lowermost surface of the block, and at least a first and second weight bearing pad extending from the upper surface, the block having a depth as measured from the front face to the rear face, the first weight bearing pad extending between the first surface of the rear face and the front face of the block more than half but less than all of the length of the depth of the block and the second weight bearing pad extending between the second surface of the rear face and the front face of the block more than half but less than all of the length of the depth of the block, the at least first and second weight bearing pads having a height,wherein the weight bearing pads are positioned such that the lowermost surface of the blocks of the first upper course are spaced the height of the weight bearing pad from the upper surface of the blocks of the adjacent lower course. 2. The retaining wall of claim 1, wherein the first surface of the rear face is inset a first distance from the first side surface of the retaining wall block and the second surface of the rear face is inset a second distance from the second side surface. 3. The retaining wall of claim 2, wherein the first distance is different from the second distance. 4. The retaining wall of claim 1, wherein the retaining wall blocks have at least one pin hole opening onto the upper and lowermost surfaces and at least one pin receiving cavity opening onto at least one of the opposed upper and lowermost surfaces. 5. The retaining wall of claim 4, further comprising pins. 6. The retaining wall of claim 4, wherein the at least one pin receiving cavity opens onto at least a portion of at least one of the first and second weight bearing pads. 7. A retaining wall comprising a plurality of courses of retaining wall blocks including a first upper course and an adjacent second lower course, each retaining wall block having a block body with opposed front and rear faces, opposed first and second side surfaces, an uppermost surface opposed and substantially parallel to a lowermost surface, and a depth as measured from the front face to the rear face, each retaining wall block having at least first and second weight bearing pads extending from one of the uppermost and lowermost surfaces of the block body, the at least first and second weight bearing pads extending between the rear face and the front face of the block more than half but less than all of the length of the depth of the block body, the first weight bearing pad being inset from the first side surface a first distance and the second weight bearing pad being inset from the second side surface a second distance, the first distance being different than the second distance, the at least first and second weight bearing pads having a height, at least one pin hole opening onto the opposed uppermost and lowermost surfaces of the block body, and at least one pin receiving cavity opening onto at least one of the opposed uppermost and lowermost surfaces of the block body,wherein the at least first and second weight bearing pads are positioned on the block body such that the lowermost surface of the block body of at least some of the blocks of the first upper course are spaced the height of the weight bearing pads from the uppermost surface of the block body of at least some of the blocks of the adjacent second lower course. 8. The retaining wall of claim 7, further comprising pins. 9. A method of making a retaining wall comprising: providing a plurality of retaining wall blocks, each retaining wall block having a block body with opposed front and rear faces, the rear face having at least a first surface and a second surface, opposed first and second side surfaces, an uppermost surface opposed and substantially parallel to a lowermost surface, and a depth as measured from the front face to the rear face, each retaining wall block having at least a first and second weight bearing pad extending from one of the uppermost and lowermost surfaces of the block body, the first weight bearing pad extending between the first surface of the rear face and the front face of the block more than half but less than all of the length of the depth of the block body and the second weight bearing pad extending between the second surface of the rear face and the front face of the block more than half but less than all of the length of the depth of the block body, the at least first and second weight bearing pads having a height;placing the retaining wall blocks into a first course; andplacing the retaining wall blocks into a second course wherein the weight bearing pads are positioned such that the lowermost surface of the block body of at least some of the blocks of the upper second course are spaced the height of the weight bearing pad from the uppermost surface of the block body of at least some of the blocks of the lower first course. 10. The method of claim 9, wherein the first surface of the rear face is inset a first distance from the first side surface of the plurality of retaining wall blocks and the second surface of the rear face is inset a second distance from the second side surface of the plurality of retaining wall blocks. 11. The method of claim 10, wherein the first distance is different from the second distance. 12. The method of claim 9, wherein the plurality of retaining wall blocks have at least one pin hole opening onto the opposed uppermost and lowermost surfaces of the block body and at least one pin receiving cavity opening onto the lowermost surface of the block body. 13. The method of claim 12, wherein the at least one pin receiving cavity of the plurality of retaining wall blocks opens onto at least a portion of at least one of the first and second weight bearing pads. 14. The method of claim 12, further comprising: inserting pins into at least some of the pin holes of the retaining wall blocks that have been placed in the first course such that the pins are then received in the pin receiving cavities of the retaining wall blocks of the second course when the blocks of the second course are placed. 15. The method of claim 12, wherein the first surface of the rear face is inset a first distance from the first side surface of the plurality of retaining wall blocks and the second surface of the rear face is inset a second distance from the second side surface of the plurality of retaining wall blocks. 16. The method of claim 15, wherein the first distance is different from the second distance.
