4-Wheeling and camping in Arizona's western deserts with some rock hounding thrown in for good measure.

    For many of my 4-wheeling and camping trips it has been my custom to simply look at maps and find some dirt roads that I have not traveled before, or take roads I have traveled before and liked. Lately though I have been using guidebooks to get ideas for new places to go.

    For this trip I strung together several trips from my guidebooks.  Most of my trips were taken from Backcountry Adventures Arizona by Peter Massey  and Jeanne Wilson (abbreviated BAA), but one trip was from Guide to Arizona Backroads & 4-Wheel Drive Trails by Charles A. Wells.

   Harquahala Mine Road.   I got off of I-10 at the Hovatter Road exit and first went to a gem and mineral collecting site just south of the freeway.  This is Site 49 in Gem Trails of Arizona by James R. Mitchell.  I did not do any  digging, but just wandered around to see what I could find, and that turned out to be not much special -- some rocks with copper mineralization (very common in Arizona) and a piece or quartz with a fairly well formed crystal protruding.  Following that it was on across the freeway to follow the Harquahala Mine Road to Salome as described in BAA (Central trail #11).  This is a well maintained road that went past the remains of the Harquahala Mine and a small cemetery just north of the mine.  I wandered the mine site and took some pictures there and of the cemetery.

    Granite Wash Mountains.
 In Salome I topped up with gasoline (just in case) and the headed  west out of town on Hall avenue to start BAA Northwest Trail #4 that  goes through an old mining district in the southern reaches of the Granite Wash Mountains.  There are many side roads in here, and I began to pay close attention to the directions and coordinates in BAA.  On many occasions I had trouble finding agreement between my gps and the coordinates listed in BAA, but the directions and mileages carried me through without getting lost.  This trail tested the ground clearance of my stock 2000 Jeep Grand Cherokee; that combined with the fact that I was alone persuaded my not to take the spur trail to the Glory Hole Mine which BAA rates as one level of difficulty greater than the #4 trail I was following.  Evening was approaching as I left the canyons, so I found camp spot on the alluvial fan below the Desert Queen Mine.

    Four Peaks in the Plomosa Mountains. (BAA Northwest Trail #1)  I was on the dirt road by 9:30 A.M. and shortly came to gem trail #44 which is the location for jasper and botryoidal hematite.  Since it was early I spent about an hour wandering the low hills in the area.  I found some red rock that I take to be jasper, but could find no botryoidal hematite. So it goes.  A few miles later I passed near a mine close to the road.  I walked up to the shaft and noticed that it was angled into the ground at the same angle as the rock layers in terrain just above the shaft.  While climbing around the rocks above the shaft I saw a rough gray to gray-brown  gnarled rock with linear crevices in parts of it.  This reminded me of dolomite I had seen in Death Valley and surrounding areas.  I took a piece of this rock home for testing with acid.  It fizzed readily with 1M HCl, so it is a carbonate, and the rate of fizz indicates to me that it is more likely a limestone than a dolomite.  A little Google searching as I write this reveals that limestone is known in the Plomosa Mountains, so I will go with that.  After leaving the mine, the route description and coordinates in BAA were not matching my location and I was beginning to fear that I was off the trail described in BAA.  I was starting to wonder about the accuracy of the coordinates in BAA some more.  Were they in NAD27 while I was using WGS84?  A quick glance through the book in some likely places did not mention the datum of the points, so I kept on with WGS84 since that is the most commonly used datum today.  Then I came upon two couples, one on dirt bikes, the other in a Rhino.  They were stopped by the trail at the time so I asked them about where I was.  They were not familiar with BAA, but they did know the trails in the area.  From what they described, I was on a major trail that would lead me in the direction I wanted to go.  Following on, I soon determined that I was back on the BAA trail.  The book mentions some sandy sections in the southern part of the trail, but I was not too concerned at this point because my Jeep had traversed soft sand readily before, I had lots of gas for backtracking, and it was early in the day and I could camp anywhere anyway.   As I got to the sandy part I encountered something that I had not expected; instead of just a light covering of blow sand the sand was piled in fairly high ridges.  Soon I came to a ridge that was about 30-60 feet high and steeply inclined.  There was a wash with firm ground in it just my side of the sand ridge, so I gunned it to pick up speed and proceeded on. About 2/3 of the way to the top my momentum gave out and I came to a halt.  I was able to back down the slope without much problem, and then I looked for a way around this spot, but found none.  Then I contemplated airing down the tires but decided not to do that, as I could just get stuck in a place that would be hard to get out of.  I was alone so there was to one else to give me a tow if I did get stuck, so it might be troublesome.  Reluctantly I turned around.  BAA Northwest #1 intersects BAA Northwest #2 somewhere near where I had gotten off the trail, and I decided add some variety to return trip by looking for that intersection and taking part of BAA Northwest #2 toward my next destination.  Since I had been lost in this region, I entered a waypoint into my gps with the coordinates of the intersection point and headed for that.  I had noticed a  side road near where I lost my way, so I decided to turn onto that and see if it took me to the intersection point.  Low and behold, it did!  (With a little back and forth in an area  near the waypoint where I was confused about which of the trails I found would most likely go closest to my waypoint and the uncertainty about how close the book coordinates were to actual locations on the ground.)  Following Northwest #2 south and east to the paved Plomosa Road was uneventful.
    When I got home I used my topo map program with my track log loaded into it to figure out where I had gotten lost, and it was when I left the mineshaft area.

    The Bouse Fisherman.  The Bouse Fisherman is a prehistoric intaglio (also called a geoglyph) near the Plomosa Road about 4 miles south of the end of Northwest #2 and very short distance from the next trail I wanted to drive.  There is a large graveled pull-out at the parking spot for the intaglio.  The parking area is unsigned except for "No vehicle travel allowed beyond this point" sign.  A short walk down that closed road brings one to the fenced intaglio.  Here there are some placards giving a brief description of the intaglio.  For more on this feature click here.

    South Plomosa Mountains and the Southern Cross Mine. Less than a 1/4 mile north of the intaglio parking area I started down BAA Northwest Trail #3, and less than one mile into that trail I came upon a large flat camping area that had not been too badly marred by people.  It was still 2 and 1/2 hours to sunset, but I decided to camp here, as good camping spots might be hard to find as I got further into the mountains.
    Being early in camp I had plenty of time to sit down have cocktail and peruse the BAA book to read about the trail #3 and read the book at leisure looking for a mention of the datum of the coordinates.  On the third page of text there it was "NAD 1927"; the datum that USGS topographic maps use.  I was hopeful that changing the datum in my gps would now allow me to correlate my gps positions with the book entries.  In this part of Arizona the NAD27 datum differs from WGS 84 primarily in longitude, and there the difference it 0.046 minutes or  about 200 meters.  Since selective availability was turned off in 2000, it is easy to reproducibly know a location within several meters, so being off by 200 meters seemed like a lot.
    Wondering near camp the next morning I found some rock alignments that might be prehistoric; after all, this is pretty close to the Bouse Fisherman, so there was probably a significant population here in prehistoric times.  I did not however find any other artifacts at this location that might tend to confirm the prehistoric nature of the rock alignments.
    The first item of interest along the trail was the Southern Cross Mine.  Mining information can be found here.  One has to be careful exploring around here as there are open shafts that could easily swallow an errant driver/rider.  One is at the crest of a hill; if one were to drive to the left side of the road at the crest it could be down into the shaft. Some people have place some miscellaneous trash on that side of the road to warn drivers, but that is it.  Also, on the road that leads to some of the ruins, there is a steep shaft right at the side of the road.  Not a good place to stop and exit the vehicle.  Continuing my loop through the mountains I came to a couple of places where I was glad I had figured out the datum issue on the coordinates in BAA.  As I was traversing these mountains it struck me that these mountain ranges in this part of Arizona to not look like much when viewed from a distance driving along a highway, but when you get into them they can be quite extensive and complex.  Get into the heart of the range and all sorts of interesting terrain appears.

    Dripping Springs Road.  After getting gas in Quartzsite I headed east on I-10 to follow the road to Dripping Springs as described in the Wells book; trip #60.  Toward the beginning of this route I missed a turn out of a wash and had to backtrack quite away. so my mileage was off in comparison to the trip description in the book.  I soon realized that it was going to be hard to follow the route the rest of the way. This pointed out a difference between BAA and the Wells book. BAA has an advantage of 1)having more gps locations, 2) having more complete turn and landmark descriptions, and 3) resetting the trip mileages every few miles.  If I were really determined to get to the end of this trail I could have backtracked to known good location and compared my odometer reading to the trip report odometer reading and done some subtraction to figure out where the next turns were, but I just did not feel like doing that and decided to just continue on and do my best to head to the next coordinate location.  I got to a place where I did not like the character of the road any more.  I looked around and thought I could see where the next waypoint was, and there seemed to be a good road leading to it, but I could not figure out how the lousy road I was on make a connection with the road that seemed to contain the waypoint.  I decided to leave this for another day and head for the next dirt road I wanted to travel.

    Kofa National Wildlife Refuge.  For the final dirt drive of the trip I decided to visit a place I  had visited before and travel roads I had traveled before.  At the Vicksburg Road I headed south into the Kofa NWR and then a bit east to pick up the Kofa Manganese Road.  The desert along there seemed more lush and green that what I had seen in the Plomosa Mountains.  I wanted to make camp around 5 PM, but at that time I was in a pretty rugged part of the road without much in the way of good campsites, and I knew that there were many good areas to camp along the side of the road I would be traveling next, so I continued on  planning to camp at the first good place along the Red Raven Road.  This intersection can be easy to miss when traveling south because the Red Raven Road comes in at an acute angle from the north.  I spotted the road first on my gps, and then I saw the Refuge marker post.  Without those clues, it would have been easy to miss this intersection.  Sure enough,  in less than 0.2 miles along the Red Raven Road I came to a great place to camp. From there it was an easy but scenic drive back to the I-10 freeway via the Red Raven Road and Hovatter Road.
