Thanks for your quick reply. Highland Lakes is off Highway 4 coming from Nevada off 395, south of Carson. Heading through Ebbetts Pass on 4 there is a sharp left turn than heads down into the valley along the river. That is called Highland Lakes Road and it runs all the way back several miles till it dead ends at the lakes. The hills look really quite worn smooth probably from glaciers. I also noted that the placers in Rye Patch seem to be concentrated in the area of about 4500 ft too.....I am on my way up to the Lakes in about an hour for the weekend, and was going to take my detector along and try. It might be a waste of time then, but I still will enjoy digging even lead too I guess. At least I can practice a bit! I am still learning the ropes, wondering if maybe the Nevada side of the 4500 ft range might be promising.
