Pyramid G1-d

Pyramid G1-d is a satellite pyramid within the Khufu pyramid complex on the Giza plateau [1]. The pyramid was discovered in 1992, during work to remove a road, about 25 metres east-southeast of the southeast corner of the Great Pyramid, and about 7 metres west of the subsidiary pyramids G1-b and G1-c [1]. The pyramid's original base length was 21.75 metres, with a height of 13.8 metres [1]. Joseph Dorner established the mean slope to be about 51°45', very similar to that of the Great Pyramid [1]. The substructure consists of an inclined passage of 25–28° which runs north to south [1].
