I'm writing a specific review for this field trip, which is part of the larger Gem-O-Rama http://www.yelp.com/biz/gem-o-rama-searles-valley event because technically you can just register for an field trip as a stand alone, and not do any of the other activities.
Usually on Sunday (the second day of Gem-O-Rama). In fact, we arrived Saturday night, and only attended the Pink Halite Field Trip. The Pink Halite field trip is probably the most physically demanding of all the field trips at Gem-O-Rama. It involves prying, wading, hacking, chipping, feeling, and moments of disappointment and excitement.
First of all you have to register at 7:30AM on the morning of your field trip, at the Searles Lake Gem & Mineral Society lapidary and show building. And we were there, right after getting the pancake breakfast at the Trona Community Church just a few blocks away. People were already starting to gather and get in line. $15 pays for one car, with however many people and equipment it can fit.
YOU WILL NEED: You can rent a heavy bar (1 inch solid steel, 6 feet long, with a 2 inch shovel blade), for $40 from the General Store inside the show room. (You get $30 upon return of your pole). You will have to bring a good hammer, buckets, boxes, and heavy gloves. I also recommend wearing clothes you don't ever plan on wearing again, a t-shirt (sun burn protection), and wide brimmed hat, pants and old sneakers or boots.
Now how do they organize this event, if several hundred people are going to it? They set up a convoy system. Outside the show building they have rows where you can park your car in. When it's time to leave and be led to the brine fields on the Searles Valley Minerals Inc they have one line go, then another. SO I recommend parking your car, then going to register and pick up supplies you might need. But make sure you get back to your car, they start the convoy at 9AM sharp.
WHY am I giving you this specific advice? Well collecting Halite is a dirty, wet, smelly, and strenuous. To understand more about Halite and the collecting process I suggest checking this link out http://www1.iwvisp.com/tronagemclub/Lake-Collecting.htm and google Halite to find out more about this mineral form of sodium chloride. Also watch the repeating video in the show building for tips and information about the field trip.
THE FIELD TRIP: Everyone parks on big salt flat, and lugs their equipment out to the designated Brine Pools (about 1 square mile across). First of all the smell of sulfur and salt water is intense, it only gets worse in the pools, but you get used to it. You'll hear popping from the air cannons randomly, they are there to scare the birds away. You walk on salt, which sounds like glass and cornflakes, and can often crack beneath your feet, watch your step. In order to harvest you'll have to feel around for ledges in the pools, which means getting in. The rust to merlot colored stuff floating in the pools is dead salt-loving bacteria. Don't worry, they just smell bad and don't bite. Basically Feel under the ledges, if you feel square places, that's Halite. Start hacking! Use your pole to pry and crack. Flip it over and see what you got!
I won't tell you much about the tricks of the trade, that's something you have to learn on your own. We ended up with two nice specimens, red and green. Green being very rare. But it took us about 3 of the 4 hours to finally find a pool that had the right signs. I fell in using all my weight on the bar to get the green ledge out.
When the field trip ended, everyone hiked back to their cars to bring them around to pick up the rocks, equipment and salt encrusted people. Little did we know we had traversed the entire square mile of bring pools to the other side!
Anyway...if you plan on doing this, do your research. It could be terribly miserable if you are not prepared. You'll get angry, you'll get sad, you'll get glad! When you find that perfect matrix you'll be hooting and hollering. We heard lotsa folks doing it! Some people brought gurneys and specially made carts to haul their rocks out.
At the end of the day your cloths will be stiff as a board, shoes completely wrecked, you'll smell like rotten eggs even after you shower, and you might get sunburned. You'll have bruises and scraps and won't want salty food for a while. But you'll drive home with some great stuff! read more
