Large, shiny metallic object hovering over Santa Rosa Indian ReservationI was driving alone eastbound on State Highway 74 toward Palm Desert. I saw a shiny metallic object hovering over an undeveloped stretch of land southeast of my car and west of the Santa Rosa Indian Reservation. It appeared to be about the size of a helicopter cabin, shaped a bit oblong and maybe 500 feet above ground. I did not stop my car but slowed down to about 40 mph so I could study the object. It was definitely not a helicopter as it had no rotors or tail. A car came up behind me so I sped up as no turnouts were nearby and lost sight of the object.
