The discovery of more than two hundred microspherules ranging in size from 40Ám was made at Westwater, Utah in 1999. These magnetic, metallic and glassy silicate particles were collected from what appears to be the bottom of an ice dam lake located on the Colorado River.

A scanning electron microscope with energy dispersive spectrometry was employed to investigate these particles. Basic chemistry results are suggestive but not a defining factor in determining microspherule history. However, specific secondary melt characteristics observed as ornamentation on microspherules greater than 200Ám and less than 600Ám (?) support the extraterrestrial provenance for these particles.
