The area provides an opportunity to observe one of the ancient rock formations that make up the Earth’s crust, with massive multicoloured [[quartzite]] rock formations rising from the sand dunes to the east and a dry fossil lake bed to the west. These rock formations are called ''inselbergs'' ([[Germany|German]]: "island rock"), denoting a prominent isolated hill rising from and surrounded by an extensive lowland [[erosion]] surface in a hot dry region.<ref>''The Unique Rock Formations at Joshua Tree NP'' [http://www.desertusa.com/magdec97/rock/rockpile.html desertusa.com].

Three of the inselbergs form a cluster which, because of their height, shape, and spatial relationships have given rise to a distinctive name for each: ''Male'', ''Female'', ''Child'', and ''Grandchild''. At 400m above
