+family0fnine Posted February 13, 2004 Share Posted February 13, 2004 What exactly does it mean when a mark is recovered? Does it mean it has been replaced? Will it state if it's been replaced? I was reading marker DU2168 and the recovery comments mention that they found a 4' irrigation ditch where the station used to be. It doesn't say destroyed or anything but could it/was it replaced?

2oldfarts (the rockhounders) Posted February 13, 2004 Share Posted February 13, 2004 Recovered just means someone actually found the benchmark. If a particular benchmark is replaced it will be listed as a "reset". Hopes this helped. John Quote Link to comment
+family0fnine Posted February 13, 2004 Author Share Posted February 13, 2004 So... If the NGS docs state "recovered" but don't say anything about "reset"... it's probably not there? Quote Link to comment
CallawayMT Posted February 13, 2004 Share Posted February 13, 2004 No, "recovered" means that the marker is still in place and was found by that person. Quote Link to comment
2oldfarts (the rockhounders) Posted February 13, 2004 Share Posted February 13, 2004 If NGS states it was recovered then the benchmark was there on the date it was recovered. If conditions have remained the same then the benchmark should still be there. If there has been any construction in the area it is possible the mark was disturbed. If the last recovery was quite a long time ago the mark may have gotten covered over with dirt and other debris. Recovered means someone went there and looked at the disk. They did NOT remove the disk. Resets are done when a mark needs to be moved from its position for some reason, usually construction of some sort. The reset is usually a "new" disk that is stamped with the same designation and the word "reset". How's this reply? John Quote Link to comment
+family0fnine Posted February 13, 2004 Author Share Posted February 13, 2004 Yea, make sense. Well, sorta. I've been reading the actual NGS reports and it's beginning to look like the NGS calls any report other than Destroyed (Good, Not Found, Needs Maintance, etc) a Recovery report. Quote Link to comment
+chaosmanor Posted February 13, 2004 Share Posted February 13, 2004 ...it's beginning to look like the NGS calls any report other than Destroyed (Good, Not Found, Needs Maintance, etc) a Recovery report. I do believe that this is a correct evaluation. When one files a report on a "found" mark, they call it a "Mark Recovery Entry". If the thing has been destroyed, they ask that you not file an MRE (their MRE, not the Army's type ), but e-mail Deb Brown, instead, with the information. I may be wrong, but I believe that in surveying, the use of a station is called "recovery". By "use" I mean putting a transit/theodolite/whatever above the station, measuring the distance from the light in the device to the disk, and then making some meaningful measurement of the distance to another spot on the landscape. When one reads an entry that says somethng about "distance of light above disk was...", that's what they are refering to. My dad was an architect, and I learned a lot from him, but I've also forgotten a lot, too, so my explanation here may be off Quote Link to comment
Z15 Posted February 13, 2004 Share Posted February 13, 2004 Recovered is their jargon for FOUND. Granted it is not the accepted meaning of the term but it has carried over from early days of the C&GS. Quote Link to comment
