Upside down tear drop in the sky West of Tooele valley.

While in the West portion of my yard, my wife observed a bright white light in the sky to the West of our location. She brought it to my attention and I immediately began filming with my cell phone. I filmed for about 1 minute, but could not make out much other than the overall shape of an upside down tear drop. I called my neighbor to come out and look and he brought a spotting scope out with him approximately a half hour later. We set the scope up and began viewing at 60X magnification. While magnified we could see what appeared to be ribbing traveling vertically along the tear drop with a roundish object underneath and a tail hanging below. We took a few photos through the spotting scope to have a comparison to anything we could find on the internet. I searched high altitude balloons and saw a very similar photo to the ones we had just taken. I believe this was a high altitude balloon upon further research.
