The horizontal fractures depicted in the Photographs below can be interpreted as sheeting joints because they are parallel to the ground surface, shallow, persistent, and closely spaced.

In this case the rock is a massive granite and the sheeting joints are connected through relatively sparse vertical fractures (left side of the larger Photograph). The weathering (brown color) accompanying the sheeting joints may indicate a present day or recent existence of flow along them.
