N8Longly you tease,
That is a fine nugget and out back of your house in a town called Foresthill, where's that. I've been in a few little towns in the out back of CA one is sorta picturesque with a split main street, a grass zone and another street, with a hotel used for weddings, an old water wheel kitty corner from an old red dirt saloon place and back down the street sorta out back of the post office and wells fargo bank is the new high school and the Carpenters place where the old loggin mill used to be. Some of those towns are all alike, describing one may sound just like another maybe even sound like your place.....follow the advice given to you and you will find all sorts of good things with your detector as when they built your town I bet they did not mine the ground first. You should know that already as you found that fine nugget out back of your place. Go getum............6bkpkr
PS - The USGS, that's united states geological survey, has a series of historical maps and sells copies of them for maybe $5 to $10. You could contact the USGS like online, as the hardware strore does not stock the old ones, and if they had an old map of the ground where your town was built on that could be interesting and might guide you to where old streams or gullies, right in town, may have been. just a thought. Imagine, prospecting the drainage ditches in an old town and finding gold nuggets in them without even having to startup your truck to drive out the FHDR. You do have a truck don't you?
Special note: if you find nuggets right in town keep your mouth shut about it! Do your detecting at night after both bars have shut down! IMHO
