A buddy & I were camped near Perfection Lake last Sat night, at ~7200', and witnessed a powerful thunderstorm off to the north. It was very distant and high in the atmosphere, and it was lighting up the entire N sky with huge white & reddish flashes (at first glance I thought it might be N Lights). We watched this for about 15 minutes, and 3 times we saw what I think were Blue Jets, a form of Lightning Sprites. I've never seen anything like it before... a thin, pale white, straight vertical line that would shoot up into space at high speed from the middle of the storm. It was amazing! We stayed awake a long time hoping to see some more, but it dissipated. I read that these things are fairly rare & poorly understood, and this might have been a once-in-a-lifetime sighting. This article has a sequence of pix that looks similar, only the ones we saw appeared even longer & brighter:

Just wondering if anyone else has ever seen these?
