1. If an area of a base map becomes cluttered by a congestion of claims, an overlay of the same material and construction as the original must be prepared in the same manner and at the same scale as the base map and used for all future plotting. If that overlay becomes cluttered, additional overlays must be similarly made and used.
Each overlay so constructed must:
(a) Be numbered sequentially for each base map for which they are used;
(b) Include the year in which the first claim was plotted on the overlay; and
(c) Precede the base map for which it overlays.
3. No information may be included on the base map or overlay to distinguish among a lode or placer claim, mill site or tunnel right. The information may be included in the description of the claim as prescribed in NAC NRS 517.160.
