+Michaelcycle Posted April 12, 2016 Share Posted April 12, 2016 (edited) I suspect that HW3332 link and HW3334 link are the same listing and that both refer to the triangulation station under the US C. &G.S manhole cover. Looks like folks are logging the actual observatory for HW332 but the data sheet is the same for both (I logged HW334 as the data sheet for that one also described the RMs) Before I make a note on HW332 I wondered what others thought?

kayakbird Posted April 12, 2016 Share Posted April 12, 2016 (edited) HW3332 (note third three) is the LEANDER MC CORMICK OBS building itself. Known as an 'Intersection' they are no longer used or recovered to NGS as covered by several threads on this forum. Still in play here though. kayakbird Edited April 12, 2016 by kayakbird Quote Link to comment

With some more digging I noticed that the datasheet locations are different: HW3334: NAD 83(1993) POSITION- 38 01 58.01420(N) 078 31 21.17948(W) ADJUSTED HW3332: NAD 83(1993) POSITION- 38 01 58.18429(N) 078 31 20.52514(W) ADJUSTED So now I think that they are two separate stations but that the description for the intersection station got mixed up with the triangulation station nearby?

I have been the navigator for our jaunts until we get to the site, I have been the decipher of the NGS datasheets as well as the GC datasheets. I have our laptop on my lap as we go with both the Delorme Topo Map program running while attached to the little gps unit and also our GSAK database up and handy. So I have gotten very familiar with how to look at these to let my hubby have the best on the spot info.... On the GC page it list this at the top. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Details for Benchmark: HW3332 Start a New Search Learn More About Waypoint Downloads N 38° 01.970 W 078° 31.342 (NAD 83) Altitude: 866 Coordinates may not be exact. Altitude is SCALED and location is ADJUSTED. (more info) Location:In ALBEMARLE county, VA View Original Datasheet Designation:LEANDER MC CORMICK OBS 1965Marker Type: NGS Benchmark Setting: setting not listed - see description~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Designation: LEANDER MC CORMICK OBS 1965Marker Type: NGS Benchmark These 2 lines will tell you all about the "Style" and "Type" of the mark. Then the next line -- Setting: setting not listed - see description Is the way the mark is set. When you see this "setting not listed and see description" - It can mean an unusual way of the mark being set or an intersection station as this mark is. The important original "Documented History" is where the major clue for where the confusion is... Documented History (by the NGS) 01/01/1965 by CGS (FIRST OBSERVED) DESCRIBED BY COAST AND GEODETIC SURVEY 1965 STATION UNIVERSITY IS LOCATED ON THE UNIVERSITY OF VIRGINIA PROPERTY IN THE SOUTH EDGE OF CHARLOTTESVILLE AT THE SITE OF THE LEANDER MC CORMICK OBSERVATORY. STATION UNIVERSITY IS 37 FEET WEST OF THE WEST EDGE OF THE OBSERVATORY, 33 FEET NORTH OF THE CENTER OF THE ROAD, 26 FEET EAST OR THE SOUTHEAST CORNER OF A BRICK BUILDING AND 25 FEET EAST OF THE NORTHEAST CORNER OF THE SAME BUILDING. NOTE--THE DIRECTION WAS TAKEN TO THE CENTER OF THE POLAR AND DECLINATION AXIS OF THE TELESCOPE. Here you see the info of the 1965 Station marked University as a reference that was used for the intersection taken to the exact center of the Polar and Declination Axis of the Telescope. The information of Station University was included just for clarification, or the Reference for the Intersection Station. So, two different data sheets for two different Designations and Types of marks - one a Benchmark Disk and the other - the Intersection Station. That is a beautiful old Observatory!
