The following ratings are for WindRock OHV area roads and trails in dry conditions. The effect of snow or rain varies greatly depending upon the trail, and can render a trail impassable. Driver Beware!

1.            Dirt/gravel road maintained for high clearance 2WD and 4WD use in adverse conditions.

2.            Dirt/gravel road with infrequent or light maintenance after rain or snow, 2WD high clearance with low gears, otherwise light duty 4WD.

3.            Road with frequent use, but seldom maintained. Dirt, some mud and some rock surfaces, with water filled mud holes may exist.  4WD recommended under most circumstances due to ruts, wash erosion, or mud holes.

4.            Road/trail surface consisting of loose rock, dirt, mud holes and rock surfaces.  Erosion, washes, gulches, water up to 12 inches deep and rock steps no higher than 12".  Moderate inclines or declines may be present.  4WD is recommended with good ground clearance and driving skills. Aggressive tires and limited slip would be a plus.

5.            Trail surfaces are rutted, rocky and maybe muddy with rock steps not exceeding 14".  Aggressive inclines or declines may be present.  Water not exceeding 15" with some mud possible. Good vehicle approach and departure angles are helpful. Tall tires (33" plus) and traction added device (lockers, limited slips) is recommended.  Above average driving skills are desirable.

6.            Trail is difficult with considerable erosion damage repaired just enough to be passable. Water in excess of 15" is possible with mud conditions. Steps not exceeding 24".   Steep inclines or declines may be present. Tall tires (33" plus) with traction added devices (lockers, limited slips) are recommended.  A winch would be a plus.  Enhanced suspension travel and ground clearance are helpful.  Excellent driving skills are recommended.

7.            Trail consists of rock, dirt and boulders and/or mud with steps exceeding 24".  Extreme inclines and declines possible.  Enhanced off road equipment is required including locking devices (front & rear), tall tires, maximum vehicle ground clearance, and tow hooks.  A winch is desirable.  Excellent driving skills are required. Vehicle mechanical or body damage is likely.  Roll over possibilities exist.

8.            Extreme trail similar to #7 except a bit more extreme.  Excellent driving skills are required. Vehicle damage is likely.  Equipment or mechanical damage is probable.  Frequent use of your winch may be required..

9.            Extreme and beyond, similar to #8.  Vehicle damage is likely.  Excellent driving skills are required.  Roll over is very common.  Winches, spare parts and tools are recommended.  Be prepared to spend the night on the trail.  Beyond the capability of most modified stock vehicles.

10.        Let the carnage begin!  Buggy territory.  Street driven 4X4’s should not attempt this trail. Modified factory vehicles will not be able to complete this trail.

NOTE:  The Knoxville Wranglers Club has established this rating system for use by its members.   However weather and usage constantly alter the routes.  Due to prevalent soil conditions, a light rain can change a moderate trail to impassable in an afternoon.  It is always wise to obtain the most up-to-date information prior to departing for a trip, and be prepared.  Remember, turning back is usually an option as well.
