Mores Creek Summit Snotel Data: 1.19.2008

I just got back from Jackson Hole, and it was COLD. It was the first time ever that I broke trail with my down coat on. It was -18F at the pass Thursday morning, and it warmed by mid afternoon to a balmy -14F. With the wind, the windchill was in the -30F.

Getting back to business, the Mores Creek SNOTEL data suggest that the snowpack has settle by as much as 12-13 inches since the last storm cycle. This settling is benefitial, since it generally leads to a more stable snowpack by reducing the shear stress caused by differential creep rates.

The SNOTEL summary data for the season is included below:




The temperature data suggest that a melt-freeze layer and/or sun crusts might have developed after 1/12/2008 at some elevations and aspects, and that there was a significant cooling period (1/16-1/17), quite possibly resulting in the formation of surface hoar or near surface facetted crystals. However, the wind might have obliterated or inhibited the formation of surface hoar.

Can we get snow conditions observations posted on this blog? That is the purpose of this Blog.

In a different note, we need to be good stewards of the Mores Creek Summit area and follow some simple "ettiquete" and safety practices:
  • Please step-off the the trail when in need of watering the lillies. Yellow snow on the trail is very unsightly.

  • Remove the dog curd from the trail. It is even worse than yellow snow. We do not want to end up like in the Wasatch, were dogs are banned from the winter backcountry trails.

  • Be mindfull of the up-hill trail routing, plase attempt to avoid having a trail that will result in riders skiing above YOU.

  • Also, be mindfull of parties at the bottom of a slope - do not ski/ride above them.

While skiing at Teton pass this week every one of the above rules were disregarded. Mores Creek is nowdays a very popular backcountry recreation location, and follwowing the above rules will make the experience a better one for everybody, and SAFER too!

That's all I have for now. I will blog again, once I can get to the Mores area within the next few days. And again, we need your observation ... do not be SHY!

  1. First post here. I am new to the area. Many years touring, mostly alone, in Juneau AK. Was up at the summit twice this last week. The earlier visit mid week, was below 6500', and the riding was RIDICULOUS. Temps had already warmed-out the rotten snow from the clear (ie. snowless) spell. Above about 6400', the rotten was easliy felt under the new while touring, so no need to waste good powder time digging. Too much air in the snow. Thus the obvious choice to stay low and rip everything. Called it a day before dark, as it was going isothermic, and things were fixing to Mudslide. Came back up on Monday to Optimize a few runouts. Snow was fully isothemic. With the snowline up to 8000,' thaw-freeze crust will be persistant. The new snow is coming in fairly warm, which is beneficial, just remember to check for stability of the new on that crust.

  2. Chris,

    Thanks for your comments! I will be looking forward to meet you, share the outdoors with you, and make a new friend.

    Welcome to to the area. I am certain that it will be easy for you to fall in love with the people and the wonderful outdoors we are privileged to enjoy.

    PS: I hope you noticed that the comment/posting was done on a blog posting dating back in 2008. That is not bad! But most blog visitors will not see it, since blogs tend to be read only when the latest post was submitted.
