Underground Mines Galore


Fields and acres of short yellow flowers covered the lower cow pocked hillsides as we headed North and East towards the Montezuma gold mining district. Higher up the mountain, light swirls and dustings of Styrofoam sleet balls sprinkled my hair as we searched, a biting chill wind testing my bones, but not quite enough falling ice to actually accumulate on the ground. We've taken this road to Montezuma many times before, but we have yet to explore all the region has to offer.







Along one dirt road, car sized blocks of pure glistening white marble can easily be seen. This area was once mined for marble but now only crumbling blocks of cement foundations remain in places where the marble blocks were once slid along cables to the main road.




In this same area, we often find small garnets. Recently, Dave found a nice pocket of large garnets and aquamarines, but this area is fickle. You might find a decent pocket right away or you might dig for hours and days and not find another. Today, we found very little other than a few very small garnets, one of which you can see in the photo.



Driving along one of the smaller brush covered paths, Dave also found a very large boulder hidden among the weeds which managed to apply a very large dent to the right underside of his jeep, just under the passenger side door. It also tore off a chunk of plastic moulding that was left to dangle precariously. But the damage looked to be all aesthetic, so we pressed on through the high shrubs.


Later in the day, the sun broke through the clouds, dissipating the sleet, and we drove to an area where many old gold mine tunnels can be found. And we were sure to explore as many as we could. The first one was entirely flooded, the water actually spilling out along the road and into a small river. We surmised that the excavation there probably opened a small spring that may run all year around, feeding the river beside it.

However, other mine entrances were higher and drier. In the photo, you can see Dave inspecting a large vein of white quartz inside one of the mine tunnels and in another photo, you can see a closeup of one tiny gold nugget present right there in the mine wall quartz (click on photo for larger view). Yes, squint very hard, it's that tiny speck! As often happens, the gold was present in areas of white quartz that had heavy iron staining (that reddish color on the quartz) and also dark almost bluish staining that indicates presence of other metals. Dave did his best to collect what nuggets he saw and those that did not accidentally fall onto the mine floor and become lost with the other dirt and rock have ended up in a small baggie for later inspection.

Many of the mines have preexisting denizens like rats that weave large nests from dried grasses, and bats that cling onto the walls and ceiling waiting for dusk to start their activities. As I zoomed in for a photo of one of the bats, my head brushing against the ceiling as I did so, I suddenly felt a small tickle on my ear and I jumped back, only to realize it was just Dave tickling my ear and not an actual bat. He was trying to mess with me and I guess he succeeded!

Bare in mind that all of these mine tunnels were pitch black inside. We all had small flashlights but for the most part, I could see very little. In order to take photos, I would just point and click and only later find out what showed up in the flash of light generated by the camera flash. Therefore, I was rather surprised in one flash photo to see that Sesame Pooch had turned into a glowing demon eyed chupacabra dog! But I guess she needed those x ray eyes to so blithely stroll around inside the mines with us, even though any other smart and sane dog would have had common sense enough to wait outside instead. I would have been nervous of her potentially falling into a vertical shaft, but some of us had been in these mines some years earlier, so we knew there were no dangerous drop offs present.

In the demon dog mine, the camera also found many orbs which are round circle things that seem to float in the air and usually only show up in camera photos. Orbs are either specks of dust or evidence of ghosts, depending on who you ask, but for whatever reason, there were hundreds of orbs in almost all photos from that one demon dog mine, but none appeared in any photos from any of the other mines. You can see some of the orbs in the demon dog photo.

Overall, the day was fun and the scenery beautiful. I even enjoyed the sleet as, being a California girl, I see such a thing only very rarely, and it did not interfere with our rock hunt. However, we did not find much take home rock this day. I guess I will just have to instead work on the tons I already have in my front yard!

Red Fever


A giant handful of thick red garnets, the size of gumballs, their edges gently worn down during their long travels along the sandy river bottom, this vision I had in my mind as I waited in the parking lot for the others to arrive. Sesame Pooch, perhaps sensing the impending adventure, wagged her tail eagerly at my side. Of course, Dave had thought Mike wasn't coming. And Mike had thought Dave wasn't coming. So the whole thing was almost called off by accident, but finally we got it all sorted out that everyone was in fact coming. And so we came. But where were we going? That was the REAL question!

In my mind, I could only think of those garnets that Dave had shown me several weeks earlier. He had said they came from the river, clogging the sluice boxes of the gold hunters, of all places! The gold hunters had looked upon them distainfully as mere hindrances to their travails. But Dave had found the common sense to save as many of the garnets as he could. Now I wanted some for myself. Oh sure, they were rather opague garnets, and their edges were gone, but hey they were big! And they were red! And they would make a reeeeeaaaaally nice necklace after being cut into halves and made into cabachons. I have always wanted to make some garnet cabs from self hunted garnets, but in California, large garnets are not common. So far, I had only hounded small specimen samples of garnet. And yet Dave had found these large garnets right in our own backyard of San Diego! As the boys yammered on about this and that potential location for the day's travels, I realized that I had little to add other than, "Yeah but does it have garnets?"

Perhaps because they were getting tired of me, Dave did indeed assure me that a place they had finally chosen along the 76 freeway did in fact have garnets. If you could find them. But that was enough for me. We took off in 3 separate cars, I and my friend along with Mike heading toward the river and Dave going back to his house first to pick up gold pans. Why had we not brought gold pans in the first place? I guess that's just how organized we really are. And of course it ended up taking Dave two more hours just to catch up with us because the route he had chosen ended up being clogged by an overturned vehicle. And not long after he arrived, he ended up having to leave because of a prior engagement. Sometimes, it sucks to be Dave.

But at least we did arrive at the river, and eventually we did even have some gold pans. First taking up residence near a large downed treetrunk that crossed the river from bank to bank, I spent a long time digging in one spot looking for... (I think you can guess at this point) ...garnets! But there were none, not even a tiny little bitty one. Next I spent time picking up pieces of quartz and inspecting them. Since this location was downstream from several well known tourmaline mines, we could potentially expect to find any kind of pegmatite material, quartz crystals, tourmaline, kunzite, etc. Indeed, we did find many pieces of schorl (black tourmaline) as well as some half formed quartz crystals. One piece of rock even sported some tiny bright red translucent spots that might even have been garnets, but you had to squint hard to see them as they were so small. I guess I would not be making any cabs out of those!

It was hard to imagine this this lazy trickle of water called a river had only a few months earlier been a seething monster that had tried to drown Dave. As we picked through the lazy silt, Mike told me the story of how Dave had been standing behind that very same large treetrunk now in front of us, in the middle of the river, panning the sand under his feet, thinking this would be a very likely place for gold to have accumulated, when suddenly a hoard of sand flushed under the log. That was the sand that Dave had been standing on and so instantly, Dave was pulled under the log by the raging current, the underside of his chin hitting the top of the log as his feet went down and under the log. Luckily, he was, with difficulty, able to drag himself out of the current safely, but not before recieving a bit of a scare and also losing his gold pan downstream to the river current. But what kind of gold hunter loses his gold pan to a measly little river, that's what I want to know! Oh well, I guess I'll forgive him. This time at least.

Back in the present, we continued to look for gold and garnet, but most of the silt that Dave had so eagerly panned previously when the river was in high flood was now covered over by larger rocks. Rocks that were not garnet, I might add!

Eventually, we decided to trek upstream through a low but rather thick hedge of poison oak, to a picturesque water fall area where the river percolated gently between large boulders. There, Sesame Pooch frolicked happily with my friend's dog, oblivious to the dangerously itchy three lobed leaves all around her. Until eventually, Sesame, in her carelessness, accidentally slipped and fell between two steep boulders, clawing and scratching but unable to make the high leap out, panicking in her frenzied efforts to escape the water below, until my friend finally came over and dragged her out by her collar. First Dave and then the dog had almost fallen victim to this innocent looking river!

From my perspective some distance away, all I heard were a few anxious sounding exclamations from my friend about the dog and some kind of problem. But by the time I made my way over and figured out what was happening, it was already over and my dog was already running back to me where she felt the need to recuperate for all of 7 seconds before going back to leaping between the boulders in glee. In this scenic area, we took many pictures and critically inspected the silt for gold panning potential, but the sun was already slipping behind the mountain and it was time to go. Maybe next time we would bring a sluice box and find some of those garnets! Right now, I am thinking that would be the best course of action, but then again, three days from now when I find out how much poison oak response I will develop, I just might change my mind!
