  • first and second blocks, each block having a thickness, width and length;

    each block having an upper surface spaced apart from a lower surface, thereby defining the block thickness, the upper surface having a plurality of pin receiving apertures, the lower surface having a channel;

    each block having opposed first and second faces, thereby defining the block length;

    each block having opposed side surfaces, thereby defining the block width as measured between midpoints of the side surfaces, a width of the first blocks being different than a width of the second blocks;

    anda plurality of pins, each pin having a head portion and a body portion, the body portion of each pin being sized to be received in a pin receiving aperture, the head portion being larger than a pin receiving aperture and being sized to be received in a channel, the pins being configured such that when the wall is constructed from the wall block system, the head portion is configured to be received within the channel of the lower surface of a block in a first course of the wall and the body portion is configured to be received in one of the pin receiving apertures of a block in a next lower course of the wall.
