  1. Hello Doc, I spent five days in the Paradise area this past June. There is plenty of country open for detecting, and a few water filled gullies and drainages that would be good for high banking. I've been told that highbanking is still OK provided you have a settling pond. Here is what I found in that area. First off, the old timers completely changed the Geography of the area with Hydro operations. Very little overburdon anywhere to be found, and very shallow bedrock. The biggest problem I found was trash everywhere. There are literally thousends of decaying cans, birdshot, and .22 shells. I would not even bother swinging your machine until you are 1/4-1/2 mile from any dirt road. By 11:00 its to hot to swing, so I would keep it to early AM, and highbank in the afternoon. A helpfull tidbid I caught (after the game), was to work as high up as possible, and right under the lava cap. I remember seeing it at the top of a few canyons, and read some chatter about it on a few posts. It might be worth a little more research. Next time I head up that direction, I will join a "local" club. Good Luck, A/F
  2. Allen, Google earth is by far one of the best tools out there, and its free. I use it to find old workings, as once you've IDed a few known places, you can compare them with new areas your searching. Old shafts. tailing piles, and even drywasher digs are very visible, not to mention heavy mineralization. You can also link it to your garmin while in the field (with google in cache memory) and track your position realtime on your laptop. That will blow any map/compass out of the water at midnight, in the desert, 15 miles up a wash, with no real visible landmarks, or the time and patients to pull out the old faithful M&C. I back it up with NatGeo Explorer, as well as Garmin Topo. If I'm going into a new area, I can MGRS grid and print a few paper copies for quick reference vice booting up the laptop. There are five problems I know of with GPS's. The Russians shoot down all our Sats, the USAF locks us out, extremely heavy weather and snow storms (your screwed) and dead batteries or system failure. The first two are highly unlikely, and the last three are totally avoidable. I run a Garmin Map 276c in the rig, and have a Garmin Vista and spare batts as back up. As for for shitty weather, plan accordingly. Good luck, A/F
  3. I've been messing around with my GMT to look for decent sample areas to start dry washing. I picked up a handfull of the small wire surveyers flags. I kick my gain up pretty high, and lower my VSat as I want the machine to catch excessive mineralization vice cancelling it, and I also want max depth. Pick a straight line perpindicular to your wash and walk with the machine in front of you, without swinging it. Take a note of your readings, In the areas I've been working, the blond sands read around 12-15, and the heavier areas around 35-38, these numbers will change up or down with the level of gain. Take one or two passes over the same path from both directions to ensure consistancy, and drop a flag on the highest numbers. Move laterally 5 ft up and down the wash and repeat the process. I only wear the headphones so I can hear a hot rock or target that would give the survey an error, the machine will be very noisy. Sometimes it lays you out a nice little streak, sometimes a bunch of scattered flags. If your working a tight area, shorten your interval, and once you finish, step back 50 ft or so and circle your survey area from different angles, as the streak may run a direction you didn't expect. I've also started a log of my numbers for the areas I've found gold. Include your setting numbers with your area highs and lows data. Good luck, A/F
  4. Thanks Gents, Looking forward to this weekend. Jerry WSPA# 63
  5. I'll be there Fri-Mon afternoon, alone, and will bring fresh corn and flour tortillas. Looking forward to meeting you all and learning a lot. Jerry
  6. Thanks Gents, great info. What is the history behind these short dozzer sweeps to be found scatterred all over mineralized areas?
  7. I'm covered in skunk, and starting to doubt every move I make. My drive is still strong, but feel my lack of geological perspective is dragging me down. The desert is a tough nut to crack, so I'm following the old timers. Question is, are the load digs (hillside) just as productive as the overburden covered flats, benches, and gullies of the placer areas. How does your search plan differ from one area to another if any? Any examples would be appreciated. Thanks, A/F
  8. Gents I'm looking to head out to the desert for a few days. I'm leaving San Diego Tommorrow around noonish. I've got room in my rig for one. I run pretty no-frills, Silverado 4x4,PI machine, bedroll, water and good boots. I'm game to link up with another party, and flexible on locations. I've scouted the desert pretty hard this summer, and ready to take advantage of the cooler weather. Drop me a line if your game. Jerry archerfrog125@yahoo.com
  9. Another note on GPS/Topo maps. As I've seen mentioned with regards to UTM's vs Lat-Lon, and NAD 27 vs WGS 84. I've found it easier to run a pre-grided map in MGRS which is a simplified version of UTM, and much more user friendly when using a GPS/compass/map/protractor. On NAD27 vs WGS 84, NAD 27 will show much older road systems, logging/mining etc. CAUTION, make sure your GPS is set up for the correct datum relative to the maps your using, our you will be several hundred ft off which really sucks at 0200 looking for a fork in a logging rd that doesn't seam to exist!
  10. I run a Garmin GPSmap 276C with the Topo software. I've used it all over the world, and it's perfect for tracking your routes. The beauty of it is the ability to link it to your computer and dump all your saved tracks, it's also real user friendly. It's a little pricey, but worth every penny. Some of the smaller Garmins don't have the memory for that many tracks. I've actually got to the point where I keep the laptop in the truck booted up to a 110v converter, and run google earth on a cache. It lets me compare the two, I also have Topo Explorer (7.5 quad maps) set up in the same laptop as backup, and for comparison. Holly crap, I've turned into a techno geek! A/F
  11. Hello Ant Man, I'm here in SD as well, and retired USN also. I've been down range the last 5 yrs contracting, and I'm at the tail end of my extended summer break. Ive got a few more vacation months left and have been hitting the desert a bit. I'm up for an over-nighter to the AZ/CA desert at the drop of a hat. I'm looking to scout new ground. I like to travel light, freeze at night, and cover a lot of country while I learn the areas. Drop me a line, A/F
