TRAIL RATINGS (1 - 5)

Recognizing that trails are not constant in their degree of difficulty, the index requires that each trial be rated by the most difficult situation encountered.

TRAIL RATINGS	1	Passable by stock and two-wheel drive vehicles; improved dirt, gravel, etc.
	1.5	Unimproved dirt, chuck holes, dips, eroded cross cuts or sharp curves.  Two wheel drive may not be able to do.
EASY	2	Some mud holes, rocks, washes, and loose dirt hill climbs.  Four-wheel drive high range will be needed.  Street tires are acceptable. Slow easy going with four-wheel drive.  Using low range some to minimize terrain and road damage.
	2.5	Some 10" - 15" rocks/ledges.  Street tire is acceptable.
MODERATE	3	Four-wheel drive required due to terrain and loose traction for safe, easy travel.  Rocks and ledges 12 - 15."  Lo-range gears used.  Challenges for novice driver.  Clearance advised.  Street tires unacceptable.
	3.5	Wash beds, 15-20" rock ledges, hill climbs, larger boulders.  Four-wheel drive, low range used. Ground clearance definitely needed.  Traction device required in the rear.  Not recommended for the novice driver.  Street tires are not acceptable.
HARD	4	Four-wheel drive required, usually in low range.  Greatest amount of ground clearance due to moderate -- large sized rocks and obstacles.  Low air pressure, flotation tires and locked rear differentials are required.  Jacks and winches advised.  Street tires not acceptable.  Recommended experienced drivers only.
EXTREME	4.5	4.5 Front and rear locked differentials required.  Low gears and maximum clearance needed.  Large boulders, steep inclines, washouts, & off camber situations.  Recommended experienced drivers only.  Winches are sometimes required, always recommended.  33" tires or bigger recommended.
	4.5+	4.5+ Same as above but recommend a fully modified vehicle, winch, and spare parts.  Experienced drivers only.
