NATC’s Winter Test Facility is a premier winter proving ground located in West Yellowstone, Montana.  Available from November 15 to April 15 each year, our winter facility offers optimal winter test conditions from December through March, with approximately two million square feet of groomed test surfaces and expanded facilities and infrastructure.

We prepare and maintain a wide variety of surfaces and tracks and have the capability to build custom courses based on the customer’s input.  Most test surfaces are maintained at a medium pack (70–80 CTI) with virgin snow, soft pack (50-70 CTI), hard pack (80-90 CTI), and frozen and melting ice available depending on the test requirements.  Courses include, but are not limited to:

  • Vehicle Dynamics Areas:
    • Terminal Apron (2200’ X 250’)
    • Taxiway (8400’ X 75’)
    • Runway (8400’ X 150’)
  • Handling courses
  • Road courses
  • Grades
  • Ice lane with J-turn
  • Off-road virgin snow mobility courses

With our Dynamic Force Measurement Vehicles (DFMVs), we can measure longitudinal and lateral traction of tires ranging from 13” to 24.5” wheel sizes and 700 to 10,000 lb vertical load in order to test ASTM F1805 driving traction.  We also test to international snow grip standards including ISO 18106.

  • Vehicle preparation and maintenance area
  • Tire mounting and changing area
  • On-site instrumentation technicians and equipment for test support
  • On-site vehicles to support dynamic longitudinal and lateral traction testing
  • Complete on-board data acquisition equipment
