  1. The 3030 drives me crazy on the standard setting. I HAVE to use SMOOTH or LONG or I would sell it. Mitchel
  2. Steve, The old Surfmaster PI or a dual field? What is the difference? Mitchel
  3. Years ago when I did my maps of meteorite finds I got EVERYTHING by state? I don't remember now. What I do remember is that there were so many I had to turn them off by un-clicking them in Google Earth. Now that hard drive has crashed and I don't know how to get them and some other files back current or added to my history. There is a backup for that drive but I think it is zipped or compressed and I don't have that computer working for a restore. Do you think I can search that external backup drive for kml and import them into my current running Google Earth? Mitchel
  4. Very nice boys ... it is a good start. Thanks for the shares.
  5. This is an open thread for any good/bad Australian picture of gold or video adventure! Post away mates. Mitchel
  6. There are never too many pictures of specimens and nuggets. I wish more pictures were taken before they are dollied up. Mitchel
  7. Now I have cheated and looked on the map. Bendigo ... a few years ago I was going to stay there after a day of training with Ronda Hyde. I never got there but it is still on my personal map. Mitchel
  8. Feb. 2017 News from the UCLA Meteorite Gallery One of a series of monthly letters sent to visitors to the UCLA Meteorite Gallery and to others who requested to be on the mailing list. The Meteorite Gallery (Geology room 3697) is open with a docent present every Sunday from 1 until 4 with the exception of the last two Sundays in the calendar year. And it is open every work day from 9 until 4 but without a docent. It is not open Saturdays. We remind you that our website address is: http://www.meteorites.ucla.edu/. There you can find a map of our corner of the UCLA campus and instructions for parking in structure 2. At 2:30 on Sunday Feb. 26 the speaker at our Gallery Event is the co-curator John Wasson. Although emeritus, John remains active in research with most of his efforts focused on chondrules and the formation of chondrites and iron meteorites. And, as this Sunday, on tektite formation. The title of his lecture is: “Formation of tektites in thermal plumes: no craters required”. Summary: Tektites are glassy samples with interesting shapes (e.g., teardrops) and compositions similar to soils and shales that formed as a result of weathering the continental crust. Since 1960 the consensus view has been that tektites are crater ejecta. However, high concentrations of 10Be (halflife of 1.5 My) show that tektites are made from soils from the upper 50 centimeters of the crust. The best model seems to be thermal plumes resulting from accreting weak asteroids or comets that disintegrated and deposited their entire energy in the atmosphere, similar to the 1908 Tunguska event. Dust was entrained into these hot plumes and melted there; collisions among droplets led to the growth of the splash-form tektites. The lecture this month is in a new location: Geology 3656, just 40 yards west of the UCLA Meteorite Gallery. This is a larger and more comfortable room than our previous venue in Slichter, and about the same distance. Our next Gallery Lecture will occur on Sunday March 12. The speaker is Roger Fu, a recent Ph.D. from MIT who will be an assistant professor at Harvard starting this fall. His title is “The water-rich interior of dwarf planet Ceres”. New data from the NASA Dawn spacecraft has revealed that the dwarf planet Ceres (940 km diameter) shows characteristics of both "rocky" and "icy" bodies. He will talk about how the morphology and spectroscopy of the surface point to a composition with less than 30% water ice. Even so, intriguing features observed on Ceres suggest localized regions enriched in sub-surface ice and, possibly, the existence of an ancient global ocean during its early history. Reminder: You can now find the UCLA Meteorite Gallery on Social Media.

  9. Dave Now that you bring it up ... I don't care about pronouncing it ... we all want to know where it is! haha How long does it take to get there? Mitchel
  10. Ok ... language alert: headless chook ?? footy ground ?? advise (advice) We have one member here who takes your lesson a bit 'farther!' His advice is to hunt near to where you park. You don't need to go running off. If it looks good all around the area ... hunt the parking lot! We have also learned to hunt the road in and out. GB, thanks for your advice.
  11. wombat Please kick the dirt around. It will encourage some of us to come and visit you and others of us to come back. I've personally wanted to visit the Golden Triangle area for some time now. Of course there are many other places of equal or greater interest. What are your primary states? Before the dust settles we ask that you show us some of your finds by link or post. We Yanks like pictures to go along with the stories. (Some of us can't read Australian or English!) Welcome Mitchel
  12. Great gold. What were the ground conditions like? You were using the 14"?
  13. I went back to the same beach today and ... less than $1 ... so ... hunt your beach pockets while they are there! Some waves deposit and some take it away.
  14. There must be SOME mistake ... that coil can't find missed or deep gold! I know for a fact it can find small gold too. My last nugget with it was just .12 g. Thanks for your post. Mitchel
