Sorry about the Delay Josh -- got busy with my own club - actually got to meet one and go on a field trip just before the ground froze.
Parents, ha, can't live with em, con't live without em. Now, you don't say whether you can drive or not so I'm not sure how far you can get -- But Pearl is just north of Boise, and south of Emmett. It used to be a mining area and is now Gohost town - you basically have to watch for it -- only a few buildings left. Now this area has been known to produce some Kewl geodes and thundereggs. You will want to go in spring before it gets hot. It can get over 100 real quick there and whether you've been out hunting in that heat or not -- it really sucks, takes gallons of water and unless you can get some shade now and again it'll make you sick real fast. Now if you are allowed as far as Emmett - go to the dam and where the hills are just to the left (North) of the road people find fire opal (small but nice fire). About 20 miles NW of Boise -- on Willow Creek you can get some fine jaspers in outrageous patterns and colors -- at the west end and on the North Side of Eagle Box canyon the jasper is really good gem qualiity. -- If it's not privately owned these days. Even if it is, you can always ask to hunt there. Most people out here are pretty nice about letting people hunt on their land -- especially since you are young enough to have "parential restrictions" -- people are very helpful in keeping youth occupied in healthy hobbies and off the streets, so use it to your advantage, lol.
Hope that gives you some tips that you can actually get to.
