I'm pretty sure you are talking about Rose creek lastleg. That area is private land but the owners have allowed public access for hobby prospecting for years. It's a good place to get a little color.
Most of the easy access areas with gold are already claimed. You need to research what lands are open to prospecting before you go out. Prospecting another person's claim or private property is a big no no in the west. Stick to the public areas like Rose or Lynx creek until you learn to research land status.
