15 TIPS ON USING MVUMs.

3.  Most forests have a separate map for each ranger district. On the map, roads stop abruptly at district boundaries. When a trail crosses from one district to another, it is very easy to get confused or lost. A prime example of this is Moon/Gamble Gulch and Pickle Gulch (See both of these trails in our new Northern Colorado book coming in May.) In the real world, these trails are intertwined. Unfortunately, the Forest Service has a different map for each area. To maintain our sanity, we found it necessary to piece together the two maps like a giant jigsaw puzzle.
4.  The maps are very large and hard to handle. They tear easily and fall apart quickly.
5.  The maps are updated every year. Make sure you have the latest version.
6.  Some of the mapping was done with aerial photography, not actually tracked with GPS on the ground. We found a few roads on the maps overgrown and impassable. One example is F.S. 413.1 in the Moon/Gamble Gulch area. It narrowed to a single-track trail even though the MVUM showed it as a 4WD trail. The south end of F.S. 252 in the Miller Rock area had the same fate (see our new Northern Colorado book).
7.  If and when the Forest Service finishes placing new route markers in the field, the numbers are still not likely to match the MVUM exactly. For example, often on the MVUM the Forest Service puts a decimal point on a primary route, e.g. 413.1. 8.  Newly placed route markers often do not include the decimal fraction and appear simply as 413.
9.  Seasonal trails are highlighted with a wide gray line. A separate chart listing each seasonal trail shows the exact dates each trail is open. If a trail is not highlighted it means the trail is open all year. No chart is used if all seasonal dates are the same. In this case, you have to look very hard at the bottom of the map to find a single line stating this.
10.  Seasonal opening dates are not always adhered to. Sometimes wet weather or trail damage can delay opening, as happened on Kelly Flats in 2010. Often these closures are listed on the respective Forest Service Websites. If you have a long drive to the trail, look online or call ahead to be sure the trail is open.
11.  MVUMs do not show every existing road, just legal forest roads. It is very confusing to encounter roads not shown on the map. County roads are shown with a light gray line, making them appear less important, when in fact they are usually major roads.
12.  Laws for county roads are usually enforced by the local sheriff and not forest rangers. Typically, unlicensed vehicles are not allowed on county roads, but in some cases, enforcement is minimal and violations are common. Don’t assume since others are riding on a particular road that it is legal.
13.  Some very famous 4-wheel-drive trails (like Pearl Pass near Crested Butte) are county roads, not forest roads. Learn to recognize county roads when reading a MVUM, since different laws and closure dates may apply.
Some forest roads, like Gillespie Gulch in the Boulder Ranger District, are shown as open on the MVUM. The Forest Service doesn’t mention that gates on private property block entrance to the trail at both ends. Apparently, you are allowed to drive Gillespie Gulch if you drop your vehicle in by helicopter.
14.  Long before a MVUM is published, the Forest Service usually maps out other alternatives. Typically these are available online for public review. At some point, the Forest Service may share with you the alternative that is most likely to become final. FunTreks is sometimes forced to use the best alternative to select trails for upcoming books. For example, we’ve been using “Alternative G” for trails in the White River National Forest. This alternative shows that Lime Creek and Wearyman Creek trails will be closed when the new MVUM is published. Therefore, we did not include these trails in our last Colorado book, despite the fact that the trails remain open at the present time.
15.  Printed MVUMs are free at ranger district offices and most can be downloaded from ranger district Websites. A full size map is too large to print on a standard printer, but you can screen capture smaller areas and print individual trails.

Game-changer: Rough Country’s New 4” Jeep ZJ Kit Offers More Parts for Less

However, most notably this 4” Jeep Grand Cherokee Lift Kit features front and rear upper and lower control arms - a feature you won't often find on a kit like this, much less at this price! Utilizing all eight control arms in this way eliminates drive shaft vibration and keeps your steering geometry and alignment correct. The rear upper control arms keep pinion angles at the optimum degree after lifting, thus eliminating the need for a transfer case drop, thereby providing additional clearance – you won’t see features like this in other ZJ kits! This Series II kit retails for $599.95 and is available by ordering online or by phone at 1-800-222-7023.

Formed in early 1970’s, Rough Country Suspension® Products was a founder of the off-road industry and is one of the fastest growing manufacturers and marketers of lifted suspension packages and off-road accessories for 2wd and 4wd trucks and SUVs.

JK Suspension Kit Released by Rough Country

The kit includes both front and rear coil springs which have been factory tuned based on Jeep’s stock spring rate allowing maximum off-road absorption while maintaining incredible highway handling. A drop pitman arm and track-bar bracket help promote proper geometry of drag link and steering parts once the vehicle is lifted. The innovative track-bar bracket also features an extra mounting hole for securing the infamous weak spot on the stock JK bracket.

Rough Country’s Series II Lift Kit also includes a pair of fixed lower control arms complete with an innovative High Clearance Design for optimum flex and OEM style rubber bushings that provide unparalleled vibration absorption. Debuting along with the 3.5” kit are a complete set of Rough Country’s new N2.0 shocks which incorporate self-adjusting velocity sensitive valving. This technology allows for variations in resistance valving according to piston speed which allows for a super smooth highway ride and outstanding control in rugged off road situations from the same shock, without turning any knobs or shock removal for re-adjustment.

Formed in early 1970’s, Rough Country Suspension® Products was a founder of the off-road industry and is one of the fastest growing manufacturers and marketers of lifted suspension packages and off-road accessories for 2wd and 4wd trucks and SUVs.
