Event Description

Hey guys, sorry for the trail change.  Sunflower Mine just has too many unknowns at this time.  We’ll get it back on the list soon.   El Oso Mine / Jolene Mine is another trail that we haven’t run in quite a number of years.  Distance-wise, it isn’t too long I’m guess 5-6 hours from the start of the 4 Peaks trail at the Beeline Hwy.  As the name denotes, there are 2 mines, of sorts, on this trail. 

The brush is probably fairly thick so there is 100% chance for AZ pin striping and we may run into low hanging limbs that may need to be trimmed to allow passage.  There is one climb that is loose soil and rocks and usually has some pretty serious erosion ruts that need to be navigated that includes one or two rock shelves.  A functional transfer case with low gear is a must and CDL would be very beneficial.  

The rocks are sharp up in this area, so solid All Terrains are required along with a full sized spare.  Stock size should be adequate.  Diff guards and rock sliders are always a good idea, as we don’t really know how large the rocks will be.   Weather should be nice.  Looks like the forecast will be partly cloudy with temps in the high 60’s t low 70’s up on top.  

Communications (please bring your radios): HAM frequency:  simplex 146.58 and we’ll have easy access to the Mt Ord repeater FRS: channel 7 with no security or sub channels   Meeting place and time: Chevron gas station at Fort McDowell and the Beeline (across 87 from the casino at the bottom of the hill after Shea)


8:30-8:45am leaving at 9am   Please register or unregister so I know who to expect.  If you need to contact me, my cell is 6O2.3I8.fiveI64

Venue Description

Four Peak, south of Hwy87 from FR143

The Four Peaks area and the El Oso Mine trail is a great place to explore within a short drive from Phoenix. I wanted to lead a trail for the 4x4wire Arizona Isuzu and Mitsubishi group, and felt that this trail would make the perfect introduction. We met at the start of the El Oso (four peaks) road, with everyone showing up at about 9:30. We made introductions and started to air down in preparation for the 18 mile drive on the graded road (designated FR143). This area is popular for all OHV users, so quads and trail bikes are to be expected, especially close to the highway.

Climb in elevation in the Mazatzal Mountains on FR143. This road eventually ends at Punkin Center NW of Theodore Roosevelt Lake. The trail rises to over 5,000' and reaches a saddle at Pine Mountain. This is where FR422 (Edwards Trail) heads north leaving FR143. This road is still tame and has a few steep climbs, but traction is good. At FR463 (N33 44.741 W111 22.175 NAD83) we left the main the El Oso mine trail (FR422) and start on the Joline Mine trail. This is where all of the challenges are encountered.

Within a few hundred yards of FR463, the trail yields some challenges, including some nice slabs that will test the suspension travel of the vehicle. This portion of the trail runs along a ridge overlooking Big Pine Flat, with some nice views. This area was damaged by fire many years ago, and is now just recovering. The brush here is very tight, and is the worst you will find throughout the loop.
