White Sands
1933
Otero County, New Mexico
Public domain · Wikimedia Commons
The largest gypsum dunefield on earth, 275 square miles of it, white because gypsum does not absorb heat and the sand stays cool underfoot. Fossil footprints found here in 2021 were dated to around 23,000 years ago, which would make them the oldest firm evidence of people in the Americas.
That was 1 of the hidden places.
