Frosted Delight

This is a photograph of the same fallen tree trunk as in my previous post.  But the area of the trunk in this photograph still has the bark in place.  The circumstances under which these two photographs (and other different photographs to follow) were made were somewhat unexpected and interesting.  This photograph was taken in Zion along Pine Creek at 3:10 in the afternoon on 11/12/2015.  When I got out of my car to head up the trail, the temperature was in the upper 50's.  But within the first quarter of a mile there was frost in numerous places along the trail and along the creek ... frost on the ground, frost on fallen leaves, frost on fallen tree trunks and branches.  This trail does remain in the shade most or all of the day at this time of year.  And I would not have been so surprised to have seen frost in the early morning hours, even though I believe that frost in Zion and other high desert environments is a somewhat rare occurrence due to the usually low humidity.  But frost at 3:10 in the afternoon with the temperature in the 50's?  It was quite unexpected.
