Medicine Bow Nordic Ski Patrol
Patrol Log:  Wednesday, January 4, 2006:  Mark Vandervort
A friend and I skied in the Greenrock area today.  I stopped by Myron's house for a radio but found none.  I'll give him a ring to make sure I'm not looking in the wrong place.  At any rate, we unfortunately found the Greenrock parking area unplowed as of yet and so we parked just below the turnaround.  There were 8 other vehicles parked.
 
At 9 am the temp was 19 deg F and the snow-stake measured at 41 inches.
 
We dug two snow pits at the top of the "Ladies Downhill" just off the Libby Creek trail on a 27 degree slope.  The snow was around 40 inches deep with a significant ice crust layer about 27 inches deep in the snowpack.  A shovel shear test indicated several weak layers in the snowpack (two very clean shears), however a compression test indicated low energy in the snowpack.  The temperature of the snowpack was 29 deg F near the ground and 21 degrees twelve inches below the surface of the snow.  Thus, there was a 8 degree Fahrenheit temperature gradient over approximately 35 inches of snow.  Snow crystals consisted of mostly rounded crystals.
 
A rutschbock test provided failure after one hard jump.  The failed slab did not slide easil! y down into the snowpit.
 
After that - we skied some great powder.  Ye-ha!
