The Arizona Land Rover Rally claims this system is used by the Arizona State Association of 4 Wheel Drive Clubs. However, it looks more like one of the Black Hills systems and we have found a system more closely associated with the ASA4WDC.
1 | 1-2 | Passable by stock and two-wheel-drive vehicles; improved dirt, gravel, etc. |
2 | 3-4 | Ground clearance required for stock two-wheel-drive pickups, vans, etc. Some mudholes or rocks that would stop most vehicles. Four-wheel-drive makes travel easy where others would have problems. |
3 | 5-6 | Four-wheel-drive required in places, due to terrain and loose traction, for safe, easy travel. Low-range gears used occasionally. Street tires unacceptable. |
4 | 7-8 | Four-wheel-drive required, usually in low range. Greatest amount of ground clearance handy due to moderate sized rocks and obstacles. Jacks and winches advised. |
5 | 9-10 | Not advisable for novice drivers without experienced help. Potentially dangerous situations! Maximum ground clearance and lowest gears required. Jacks or winches indispensable when needed due to large boulders, steep inclines, etc. |
Note: Trail ratings are highly subjective. A trail that is easy for an experienced driver with a highly modified vehicle may be impassable for a novice driver in a stock vehicle. Weather conditions may also significantly affect the difficulty of a trail. Also, the difficulty of a trail may change over time, as trail use, weather, and maintenance modify the trail. Always check with the managing organization and/or recent users before planning a trip on a trail and scout ahead on foot if you are not sure of current conditions.
