Figure 6 shows the ABC and XYZ lodes, both of which are being surveyed for patent under the same survey order. The discovery shafts of both claims are in the area of conflict. In order to validate the claims, a new discovery must be shown for one of them, outside the conflict. It need not be the later claim as the owner has the right to decide which claim shall exclude the conflict. If amended location certificates are filed for record, it will be necessary to make an amended application for survey to the Bureau of Land Management based on the amended certificates, and receive an amended order for survey. It will not be necessary to suspend field work pending such amendment, but it is advisable to refrain from marking the corners and accessories with the survey number until the amended order is received.

Bottom: a stone corner chiseled with the corner number, the initial of the claim and the survey number. ] [Illustration: FIG. 5 ] [Illustration: FIG. 6 ] =5–4= Monumenting the Survey: Section 10–35 of the Manual of Surveying Instructions, 1973 lists corner monuments in their order of preference. Accessories to the corner generally consist of bearing trees or bearing rocks. If trees are available, two different species at approximately right angles from each other to the corner should, if possible, be selected and marked differently so that each can be readily identified. For example: one might be a Douglas Fir, 10 inches diameter, bears N. 10° E., 20.65 feet dist., blazed and scribed 1 W—2826 X BT; the other a Ponderosa Pine, 7 inches diameter, bears S. 70° E., 12.52 feet dist., blazed and marked X BT. In each case the measurement should be taken to the X which is in contrast to the bearing trees to section corners, the measurement being taken to the center of the trees. If the measurement is to the center of the tree, an X should not be included in the markings. The difference between a pine, spruce and fir can be identified by the needles, the pine having needles in bundles, the spruce having needles square in cross section, and the fir having flat needles. Bearing rocks should be marked X B O or X B R with the measurement taken to the X; the rock or outcrop being of sufficient size to be readily identifiable. Ties along claim boundaries to items of planimetry and drainage surrounding the corner may be taken at this time. Ties to section corners, location monuments and triangulation stations may also be made at this time if they are close to a corner.
