As of today, peak season now, through ~September 15. Earth Exhibit tracks the live conditions and flags it the moment it is on.
The Kelso Dunes in Mojave National Preserve occasionally produce loud, low-frequency 'booming' or 'singing' sounds when dry, well-sorted sand avalanches downslope.
The acoustic phenomenon is physical, produced by synchronized motion of sand grains and resonance of the moving layer in specific humidity and wind conditions.
