ffjerm Posted April 19, 2006 Share Posted April 19, 2006 I was attemping to locate an USGS benchmark near my home here in So. California when I stumbled across a benchmark labeled as 'US General Land Use Survey'. Has anyone here heard of these and/or is there a resource where I can find more info on these benchmarks. Thanks - ffjerm Quote Link to comment
+jwahl Posted April 19, 2006 Share Posted April 19, 2006 (edited) Perhaps it has a slightly different designation. Just guessing. There was a General Land Office that did Land Surveys. There could be a U.S. Survey done by the GLO. anything is possible, so what might help narrow it down is the location, if you want to five a latitude and longitude, we might be able to narrow it down. - jerry wahl I was attemping to locate an USGS benchmark near my home here in So.

+Klemmer Posted April 19, 2006 Share Posted April 19, 2006 I have also seen USE as an older abbreviation for the United States Engineers (USE), better known now as the US Army Corps of Engineers (USACE). A picture of the disc would be interesting, if you have one. You can upload it as a Note on a benchmark near the mystery disc so you can link or add it here. Quote Link to comment
+Kewaneh & Shark Posted April 19, 2006 Share Posted April 19, 2006 The United States General Land Office (now the Bureau of Land Management [bLM]) was responsible for the survey of all public lands within the United States. Their surveys were cadastral in nature and used the Public Lands Survey System (PLSS) method of land division as shown in the Manual of Instructions for the Survey of Public Lands. One of the main purposes of the surveys was to determine the area of public lands held by the United States. The PLSS is a grid system comprised of townships (6 x 6 miles = 36 square miles) and sections within the townships (1 square mile). As a general rule, the corners of each section and township was monumented. Many of those monuments were brass caps (which look like benchmarks) and labeled as GLO Survey monuments. (Other monuments used included, among other things, stone monuments, stone piles [cairns], pits & mounds, and wood posts.) Additional threads which discuss the GLO and their monuments are: U.s. General Land Office Survey Disc, (I need help) Ya 'what Mark Is This?' P Initial Points 'glo' Markers, Why were they placed at those locations?

ffjerm Posted April 19, 2006 Author Share Posted April 19, 2006 Thanks for the info. I'll take some pics and post tomorrow, with lat and long as well. Quote Link to comment
+Harry Dolphin Posted April 19, 2006 Share Posted April 19, 2006 How about one marked USED HL STA monumented by DOD in 1933? Though, it's listed as a casting, rather than as a disk. Quote Link to comment
ffjerm Posted April 20, 2006 Author Share Posted April 20, 2006 Ok....here it is. I'm not sure how well the pic will upload, so I'll give a verbal description as well. Outer edge of disk is stamped 'U.S. GENERAL LAND OFFICE SURVEY - 1942' I believe the ID # is T4NR3W then the center is stamped: S20 | S21 S29 | S28 N34' 24.810' W117' 12.439 Elevation of 3074 anyway, hopefully this info will help. This mark is obviously a corner marker of some sorts. It would be fun to locate some more of these. If anyone here can lead me to more resources, I would appreciate it. Thanks again - ffjerm Quote Link to comment
Z15 Posted April 20, 2006 Share Posted April 20, 2006 (edited) You got a section corner. More specifically the section corner common to sections 20,21,29 and 28; Town 4 North, Range 3 West. Technically this is not a bench mark, its a property controlling corner. Edited April 20, 2006 by Z15 Quote Link to comment
ffjerm Posted April 21, 2006 Author Share Posted April 21, 2006 Thanks.....so by theory, there is one of these every 1 mile running due east/west and due northsouth? Also, were did you find the data sheet you attached? Thanks for he great info! Quote Link to comment
