Request to Mining Claimants on Federal Lands: Help Eliminate Hazards to Birds and Other Wildlife
Open-Pipe Mining Claim Markers Pose a Threat to Birds and Other Wildlife
Open-pipe mining claim markers, such as polyvinyl chloride (PVC) pipes, can be lethal to migratory birds and other wildlife. Small animals, particularly birds, mistake the openings of these markers as hollow areas suitable for roosting, nesting, or a way to gather together to pool body heat. Once inside, these animals become trapped by the smooth, narrow wall of the pipe, which prevents them from grappling their way back up or extending their wings to fly out. Death from dehydration or starvation follows. Cactus wrens, mountain bluebirds, western meadowlarks, flycatchers, and woodpeckers have all been found within open-pipe mining claim markers. While not all mine claims are marked with pipes, the existing open-pipe markers pose a threat to birds and other wildlife in many states.
Replace Markers to Prevent Unnecessary Deaths of Birds and Other Wildlife
The BLM and its partners request the help of mining claimants to prevent the death of wildlife, including some birds that are protected by the Migratory Bird Treaty Act. You can prevent unnecessary deaths of birds and other wildlife by removing, replacing, or remediating all open-pipe markers on your active mining claim or site. Even if you did not use open-pipe markers to locate your mining claim or site, these markers may have been left on your claim by previous mining claimants.
What You Can Do to Help
• REPLACE all open or PVC pipes marking your active mining claim or site with wildlife-safe markers. All of the markers in re wildlife-safe. Be sure to consult state law to verify which wildlife-safe markers are allowable where your mining claim or site is located.
• REMEDIATE open-pipe markers, if immediate replacement is not possible and your state still allows this type of marker. To remediate open-pipe markers and reduce the chances of wildlife deaths, fill or plug the open pipe or firmly cement a cap on the end.
• REMOVE and properly dispose of any open-pipe markers on your claim or site left by previous mining claimants. Thank you for your help in our effort to reduce the number of unnecessary bird and other wildlife deaths.

Arizona Revised Statutes- Title 27, Chapter 2, Article 1
27-201. Location of mining claim upon discovery of mineral in place
Upon discovery of mineral in place on the public domain of the United States the mineral may be located as a lode mining claim by the discoverer for himself, or for himself and others, or for others.
27-202. Method of locating a lode claim; monument; location notice; amendments
A. Location of a lode claim shall be made by erecting on the surface on the centerline within the boundaries of the claim a conspicuous monument of stones not less than three feet in height, or an upright post securely fixed and projecting at least four feet above the ground, in or on which there shall be posted a location notice, signed by the name of the locator. The location notice shall contain:
1. The name of the claim located.
2. The name and address of the locator.
3. The date of the location.
4. The length and width of the claim in feet, and the distance in feet from the location monument to each end of the claim.
5. The general course of the claim.

B. Until the requirements of subsection A are complied with, no right of location is acquired.
C. The notice may be amended at any time and the monument changed to correspond with the amended location, but no change shall be made which will interfere with the rights of others. If such amendment changes the exterior boundaries of the claim, a new or amended map, plat or sketch shall be recorded pursuant to section 27-203 showing such change.
California Public Resources Code Section 3915.
(a) The following are the only monuments which may be used pursuant to this chapter:
(1) A wooden post not less than 1 1/2 inches in diameter projecting at least two feet above the ground.
(2) A mound of stone projecting at least two feet above the ground.
(3) A nonperforated, capped metal post or solid metal rod, not less than one inch in diameter and projecting at least two feet above the ground.
(b) Where, by reason of precipitous ground, it is impractical or dangerous to place a monument in its true position, a witness monument may be erected as near thereto as the nature of the ground will permit and marked so as to identify the true position.
(c) Where, by reason of working the claim, it is impractical or dangerous to maintain a monument in its true position, a witness monument shall be erected as near thereto as the nature of the ground will permit and marked so as to identify the true position.
(d) Any person using on January 1, 1992, or who has previously erected, any monument or object other than those defined in this section for the purposes of this chapter shall have until January 1, 1995, to comply with this section or remove those monuments which are not in compliance.
(e) Within 180 days of abandonment, relinquishment, or loss of a, in effect on January 1, 1992, all monuments pertaining to that claim shall be permanently removed by the locator. A person who
violates this subdivision shall be subject to a fine of not more than fifty dollars ($50) for each monument which is not removed and additionally liable for any cost incurred by the federal, state, or county government agency which removes any monument or has it removed.
C.R.S. 34-43-107. Marking boundaries
Such surface boundaries shall be marked by six substantial posts hewed or marked on the sides which are in toward the claim, and sunk in the ground, one at each corner and one at the center of each side line. Where it is practically impossible on account of bedrock to sink such posts, they may be placed in a pile of stones, and where in marking the surface boundaries of a claim any one or more of such posts fall by right upon precipitous ground where the proper placing of it is impractical or dangerous to life or limb, it shall be legal and valid to place any such post at the nearest practicable point, suitably marked, to designate the proper place.
Idaho Code Section 47-602. Method of locating mining claim. The locator of a mining claim must at the time of making his location designate his claim by posting at one (1) corner of the claim his notice of location in writing in which there shall be stated:
1. The name of the locator or locators.
2. The name of the claim and whether located as a lode mining claim or as a placer mining claim.
3. The date of the location and the mining district, if any, and the county in which the claim is located.
4. The directions and distances which describe the claim.
5. The direction and distance from the corner where notice is posted to such natural object or permanent monument, if any such there be, as will fix and describe in the notice itself the site of the claim.
Before recording his notice of location, the locator must mark the boundaries of his mining claim by placing at each corner or angle of the claim a substantial monument or a post at least four (4) feet in height and four (4) inches square or in diameter. Each post and monument shall be marked with the name of the claim, the position or number of the corner or angle and the direction of the boundary lines. The locator shall mark the boundary lines so that they can be readily traced. Where it is impracticable to place a monument or post in its true position, a witness monument shall be erected and marked to indicate the true position of the corner or angle.
Montana Code Annotated 82-2-101. Manner of locating claim. A person who discovers upon the public domain of the United States, within the state of Montana, a vein, lode, or ledge of rock in place bearing gold, silver, cinnabar, lead, tin, copper, or other valuable deposits or a placer deposit of gold or other deposit of minerals having a commercial value that is subject to entry and patent under the mining laws of the United States may, if qualified by the laws of the United States, locate a mining claim upon the vein, lode, ledge, or deposit in the following manner:
(1) The person shall post conspicuously at the point of discovery a written or printed notice of location containing the name of the claim, the name of the locator or locators, if there is more than one, the date of the location, which must be the date of posting the notice, and the approximate dimensions of the area of the claim intended to be appropriated.
(2) Within 30 days after posting the notice of location, the person shall distinctly mark the location on the ground so that its boundaries can be readily traced. It is prima facie evidence that the location is properly marked if the boundaries are defined by a monument at each corner or angle of the claim, consisting of any one of the following kinds:
(a) a tree at least 8 inches in diameter and blazed on four sides;
(b) a post at least 4 inches square by 4 feet 6 inches in length, set 1 foot in the ground, unless solid rock should occur at a less depth, in which case the post should be set upon the rock and surrounded in all cases by a mound of earth or stone at least 4 feet in diameter by 2 feet in height. A squared stump of the requisite size, surrounded by a mound, must be considered the equivalent of a post and mound.
(c) a stone at least 6 inches square by 18 inches in length, set two-thirds of its length in the ground, with a mound of earth or stone alongside at least 4 feet in diameter by 2 feet in height; or
(d) a boulder at least 3 feet above the natural surface of the ground on the upper side. When other monuments or monuments of lesser dimensions than those described in subsections (2)(a) through (2)(c) are used, it is a question for the jury or for the court where the action is tried without a jury as to whether the location has been marked upon the ground so that its boundaries can be readily traced. Whatever monument is used, it must be marked with the name of the claim and the designation of the corner, either by number or cardinal point.
(3) Within 60 days after posting notice, the locator shall comply with the United States mining laws.
NRS 517.030 Monumenting of claim; required removal of plastic monuments.
1. Within 60 days after posting the notice of location, the locator of a lode mining claim shall distinctly define the boundaries of the claim by placing a valid legal monument at each corner of the claim. A valid legal monument may be created by:
(a) Blazing and marking a tree, which has a diameter of not less than 4 inches, not less than 3 feet above the ground;
(b) Capping a rock in place with smaller stones so that the rock and stones have a height of not less than 3 feet; or
(c) Setting a wooden or metal post or a stone.
2. If a wooden post is used, the dimensions of the post must be at least 1 1/2 inches by 1 1/2 inches by 4 feet, and the post must be set 1 foot in the ground.
3. If a metal post is used, the post must be at least 2 inches in diameter by 4 feet in length and be set 1 foot in the ground. If the metal post is hollow, it must:
(a) Be securely capped or crimped in a manner that securely closes the top of the post; and
(b) Have no open perforations.
4. If it is practically impossible, because of bedrock or precipitous ground, to sink a post, it may be placed in a mound of earth or stones. If the proper placing of a monument is impracticable or dangerous to life or limb, the monument may be placed at the nearest point properly marked to designate its right place.
5. If a stone is used which is not a rock in place, the stone must be not less than 6 inches in diameter and 18 inches in length and be set with two-thirds of its length in the top of a mound of earth or stone 3 feet in diameter and 2 1/2 feet in height.
6. Except as otherwise provided in subsection 7, a durable plastic pipe that was set before March 16, 1993, for the purpose of defining the boundaries of a lode mining claim shall be deemed to constitute a valid legal monument if:
(a) The pipe is at least 3 inches in diameter by 4 feet in length and is set 1 foot in the ground; and
(b) The pipe is securely capped with no open perforations.
7. The locator of a lode mining claim located before March 16, 1993, the boundaries of which are defined by a durable plastic pipe described in subsection 6, or the locator’s successor in interest, shall, on or before November 1, 2011, remove the durable plastic pipe and replace the monument of location and the corner monuments with valid legal monuments in the manner prescribed pursuant to subsection 1. If the locator or the locator’s successor in interest replaces the durable plastic pipe on or before that date, the locator or the locator’s successor in interest shall, within 60 days after the replacement, record a notice of remonumentation with the county recorder of the county in which the claim is located and pay the fee required by NRS 247.305. The notice must contain:
(a) The name of the claim;
(b) The book and page number or the document number of the certificate of location or the most recent amendment to the certificate of location;
(c) The book and page number or the document number of the map filed pursuant to NRS 517.040; and
(d) A description of the monument used to replace each monument that is removed.
The notice may include more than one claim. Any durable plastic pipe that is removed pursuant to this subsection must be taken from the lode mining claim and disposed of in a lawful manner.
8. After November 1, 2011, any durable plastic pipe that is not removed pursuant to subsection 7 may be removed and placed on the ground immediately adjacent to the location from which it is removed to preserve evidence of its use as a monument for the lode mining claim.
9. The replacement of a durable plastic pipe or the recording of a notice pursuant to subsection 7 does not:
(a) Amend or otherwise affect the legal validity of the claim for which the monuments were created;
(b) Modify the date of location of the claim; or
(c) Require the filing of an additional or amended map pursuant to NRS 517.040.
