sand - dune sand - fine-grained yellow-brown dune sand derived from a sandstone member of the Menefee Formation in New Mexico - set of two 2-ounce jars
The Allison Member of the Upper Cretaceous Menefee Formation is a cliff-forming yellow brown sandstone. As it weathers, sand grains picked up by the wind form local small dunes north of Crownpoint, New Mexico. The grains in these dunes are very fine, similar in size to the grains in the pink dune sand that is derived from the Jurassic Navajo Sandstone in Utah.
It would be instructive for students to compare these two dune sands - both fine-grained but very different in color. Sand is derived from whatever materials are locally available, a lesson emphasized by these two very different colored dune sands.
