Relax! Take heart, this is not another long epistle like I wrote yesterday. But, I did want to add a note from Brian Peters. He found some additional information about the high altitude tornado that I wrote about near Provo, Utah. Here is his note:
————————————————————–
According to what I found, JB, the tornado at Timpanogos Divide occurred on December 2, 1970. Here is what I found with only a bit more information than what you posted today.
Tornado, below Timpanogos Divide, Utah County
December 2, 1970, 1503 MST, 40 24’N, 111 35’W
A high-mountain white tornado (that picked up and carried snow) was spotted a little below Timpanogos Divide, Utah County. It traveled in a southwesterly direction about a mile. The tornado was about one-fourth of a mile wide. It carried snow to above 1,000 feet and toppled trees that were a foot in diameter. There was a loud roaring sound as the tornado dipped down across the divide. One man some distance from the core was knocked down but was not injured. The twister occurred at about the 8,000 foot elevation and was observed by Tom Walker, former superintendent of Timpanogos Cave National Monument.

Thanks, Brian. Tornadoes are not as unusual as you might think in the Mountain West. How about the one in Downtown Salt Lake City a few years ago. Also, a powerful F4 plowed through Yellowstone National Park up and down a 10,000 foot mountain downing thousands of big trees in the 1980s!
