It looked like it flew across the top of the white mountains heading north toward Nevada. Bright white light the size of a soft ball with a blue train that sort of exploded to green, then shot off in full white light.
There could have been fragmentation when we saw it change color from blue to green; it seemed to slow as it did so but ended racing north beyond where we could see it land. We were driving when we saw it. Almost crashed we were so excited. Never saw anything like it.
