A Great Meteogram

The meteogram (temperature trace) from Alta-Collins for the past week is priceless.  Several days of beautiful summer-like weather, followed by a plunge to the current temperature of 20F.


Alta-Collins sits in Collins Gulch at about 9600 feet.  Looks like somewhere between 13-15" of snow on the ground now depending on which snow-depth sensor you use.

  1. I wonder if there's any chance this would mark the shortest interval at Alta between the last snow melting from the previous year and the first snow accumulating during the current one...

  2. Camera images before the storm showed a few patches of snow left over from last year on the higher peaks.

  3. If I remember correctly, Alta-Collins melt-out occurred on 30 or 31 July. Whether or not this snow sticks around for the season remains to be seen, but if it does, it would probably be a near-record minimum of no snow coverage at that elevation. Perhaps an analysis of SNOTEL data would prove insightful, although the Snowbird station only goes back to ~1990.
