Weekend Outing from 5 Years Ago

Looking back: A year-end reminiscing at what we were doing in December of 2001

Hard to believe that 5 years have gone by since our last trip to Gold Basin. It’s not that I haven’t returned to this part of northern Mohave County, Arizona, since then, it’s just that there are so many other spots in this area to search for meteorites. And when I did return, I would usually be leading a small meteorite-recovery team, and they would always opt for going to a dry lake, as opposed to going to an alluvial fan and swinging a metal detector all weekend. So, every time that we found ourselves in the Hualapai Valley, we would usually end up on a large playa near Gold Basin called, Red [Dry] Lake, and I would never find the time to re-visit the Gold Basin strewn field.
But, on this weekend our destination was to be Gold Basin. I drummed-up interest for this excursion by telling the team members about my previous recon trip and my success at what I called, “a proof of concept” meteorite-recovery. The “concept” was that, if the proper surfaces could be found, a person could find Gold Basin meteorites just by their eye-sight alone. And on that first recon trip I "proved the concept" by finding a small fragment after only a few hours of walking.
Of course, on that prior “recon trip” I was searching by myself because the other team members thought I was crazy to go to a strewn field that was “so thoroughly worked-out!” But I was able to find the “proper surfaces”; namely, erosional surfaces that were sufficiently old AND extensive.
This news generated a lot of interest among the team members, but come that Saturday morning, only two of them showed up for this excursion – James LaBarbera, the son of Jerry LaBarbera, and Daniel Abel, a friend of my son. Daniel had never gone meteorite hunting before, and although he didn’t find one on this trip, his youthful eagerness (particularly to do all the driving) gave the rest of us the added energy which would be instrumental in making this M-R effort a success.

We arrived at Gold Basin before the sun rose. The plan was to hike in to the deepest, most remote area of the strewn field before we would even start to search visually, all in the hope that we would find a suitable area that was "under-searched" by prospectors with metal-detectors. we parked the truck along the main graded-road, and James jumped out immediately in order to attend to some long overdue personal business. Now, believe me! This is no exaggeration, but before I could even turn off the engine and get out of the truck, James was already walking up to my driver-side window with arm extended, holding a plum-sized chondrite! It appears that right along side that main road, right under a bush that James had gone behind to conduct his business, is where he found the first Gold Basin Area meteorite of the day!
(Daniel suggested that I put on my gloves before examining it, "just in case it turns out to be a urinlite meteorite"!) Daniel offered to stay close to the truck. He may have been tired from driving all night, but probably was more impressed with how close to the truck was the first find of the day. So, it was up to James and I to start hiking.

Long story short, before the morning was over, I found a meteorite fragment (images below). Although I was equipped with a magnet stick, it wasn't necessary to use it to make this find. I made this find with my eyes only, and I knew this was a meteorite even from several meters away.
While I recorded the find with my GPS and digital camera, James continued searching by circling around and away in ever increasing circles. But then I remembered something that John Blennert told me. JB has found numerous clusters of GB fragments over the years and has noticed that the fragments form a linear pattern on the ground. More importantly, the trend of this pattern is nearly the same (parallel) for all clusters, roughly NNE to SSW. So, instead of having James walk a broad search pattern, I suggest to James that he turn to the NNE and start searching in a straight line. Within the next two minutes, James had made the 2nd find. I told him to mark the spot and keep on walking to the NNE. And before I could finish recording my first find, James had recovered all of the GB fragments that would be found that day! All found along that straight line.
Over 1.5 kg of fragments and individual chondritic stones.

The images below are from our 2001 December 26th visit to Gold Basin:

***************************************************

The next morning as we drove from Meadview back to Gold Basin, we could clearly see Red Dry lake out in the distance. As we drove down into the Hualapai Valley (and because the early morning light was still dim from an overcast sky), I was able to see features on the lake that I hadn't seen before. I had never noticed before how large the dunes were at the south end of the playa. The presence of such large dunes suggested to me that, contrary to thepredominant wind direction (which is from the southwest in this part of Arizona), there must have been episodes of energetic winds blowing out of the North!
And whatever direction the wind blows, that's the direction I will go; I will follow the wind to where ever those meteorites will accumulate.

It didn't take much talking to convince James and Daniel to take a detour to Red Dry Lake.

***************************************************

All of the meteorites depicted in the images below have been reported to Nomenclature Committee of the Meteoritical Society, and a provisional name WITH numbers were assigned by Board member, Rhian Jones. Most of these chondritic stones have been classified (by UCLA) and some of them have already appeared in the Meteoritical Bulletin. This means that the name "Red Dry Lake nnn" is a formally approved meteorite name, but unlike "Gold Basin area" meteorites, each "Red Dry Lake" meteorite find has been assigned a Nom Comm formally-approved number. Although this number is provisional until the meteorite is classified and appears in the Meteoritical Bulletin, this number is the only indicator of whether the find has been reported to the Nom Comm, and hence, is using "official" nomenclature, or whether it is an unreported meteorite, and hence, is unofficial.
Only if an individual mass has been assigned a Nom Comm approved number can it be considered as an officially named "Red Dry Lake" meteorite.
