WebUPPER LITHIFIED DUNE An eroded lithified dune 15 feet thick lies above the soil bed (Figs. l, 4). The calcareous sand is weakly cemented for 5 feet above the soil bed. This condition greatly facilitated the removal of the goose bones which were found near the base of the dune. Fossil land snails occur sparingly in the bone layer. The upper part of A lithified (consolidated) sand dune is a type of sandstone that is formed when a marine or aeolian sand dune becomes compacted and hardened. Once in this form, water passing through the rock can carry and deposit minerals, which can alter the color of the rock. Cross-bedded layers of stacks of lithified dunes can produce the cross-hatching patterns, such as those seen in Zion National Park in the western United States.
