Snowpack Observations

Details

Ash Creek Butte observations taken from Surprise Lake ridgeline (~6,900 feet) and the surrounding area. Most notable observations were of the current wind strength and intensity. Winds strengthened throughout the outing, moderate in the morning, then becoming strong to extreme by noon. Widespread strong winds with extreme gusts made travel difficult near treeline. Wind loading, growing cornices, and scoured windward surfaces could be found in exposed areas below and near treeline. Gale force wind could be seen tearing snow off any terrain feature near and above treeline. Southerly aspects are surely wind loading rapidly. 

Below treeline, surface conditions consisted of a sun crust in sunny exposed areas and smooth soft snow in shaded areas. Surface hoar was found in terrain surrounding Surprise Lake. To our surprise, the road back to Pilgrim Creek Snowmobile Park was covered in large tree branches and tree debris as we returned.

Except for the new tree debris, the 19 Road is in great shape for snowmobiling currently, especially with the recent grooming.
