Strataday Saturday 001 Interpretation
White Sands, New Mexico
This is the White Sands dune field of southwestern New Mexico. Sand composition is dominated by gypsum (~98%) and White Sands represents the largest dune field in the world at 275 sq. mi. Wind direction is generally from the WSW to ENE. Dune types in the area range from domal, transverse ridge, barchanoid ridge, isolated barchan, and parabolic, reflecting the decrease in grain supply from west to east.
