These tests were listed at http://goldpanfever.com/blogs.html . They are ways to tell pyrite from real gold.
Real gold or fools gold ?"If what you found was sparkling right on the surface without digging down you might have mica or some other type of “fool’s gold”.
Here are some quick tests to check if you found real gold.
Sun Test: Once you have seen your first Gold you will never forget it. A quick and easy test is to note the color and brightness of the gold in your gold pan. Now shadow your Gold pan. Anything that is not Gold will become dull or fade. Gold will retain its color and luster – it will still be golden, just Gold in the shade.
All that sparkles isn't Gold: Look at the material in the sunlight if it sparkles it is a 99.999 chance it is not gold.
Pin test: stick a pin in the “gold”. If it breaks or fractures or crumbles it isn’t gold. Gold is malleable and ductile meaning you can bend it and dent it. Lesser minerals will crack, break or crumble.
Pan test: One of the first things to learn about gold is it is very heavy. Gold really doesn't move around in your pan much. After panning your material down to your final cons, rock your pan back and forth with a little bit of water in the pan. You will find that the Gold will mostly stay put, while other light weight material moves away. As the light material moves away tap your pan lightly on the top edge. This will separate the heavy gold even further from the waste. Consider the source and location. If you found your “gold” on top of other dirt it probably isn’t real gold. Gold is extremely heavy and will always seek the lowest place to rest - often on top of bedrock or other hard material such as clay or limestone."
In the late 1870's, hundreds of mines were burrowed into the hills of California in Summit County.
With 5 shafts and 10000 feet of underground workings, the Washington Mine was a big gold producer. The address is 465 Illinois Gulch Road just off Boreas Pass Road. More directions to the site are provided at the address below.
Hours of Operation: 11am to 3pm, Tuesday - Sunday (Mid - June – Labor Day)
The information at this site is very interesting. I always like to investigate areas when I go on vacation. A side trip to a mine is great recreation for me.

This is a set of instructions at eHow about building a sluice box. In five steps, this article will show how to construct it with a skill saw or hand saw, screws, a drill, knife, wood 2 by 4, and a piece of plastic sewer pipe. http://www.ehow.com/how_5185082_build-gold-prospecting-equipment.html The nice thing about these articles is that eHow focuses on how to make the instructions simple. These well-stated articles can save a lot of time and headache.

Here is an article showing how to make your own thermos. Not sure how practical this is for most of you, but this seems a way to make a pretty good one using a standard plastic water bottle and a 2-liter bottle. Epoxy is the insulator.
