ipuppy Posted June 5, 2015 Share Posted June 5, 2015 Greetings - I made a quick urban benchmark run yesterday morning and one of the marks I had on my list was JV6912. NGS Datasheet I had little hope of finding this one as it is in an area with a lot of change like most waterfront areas around here - transitioning from heavy industrial to other uses. Interestingly it is described as an "ESSO Standard Oil Company disk" which I'd never seen before. The references include nearby oil tanks which I knew had been demolished at least a decade ago, so I assumed the area had been thoroughly altered, likely obscuring or destroying the mark. I arrived at the busy intersection - there is lots of traffic, both commuters and trucks, as there is still a lot of industry in the area. I quickly found what looked to be the "top of a concrete post flush with surface of the ground" and "about 0.5 ft higher than the road." But the concrete had no disk, and there was what appeared to be the stump of the stem in it. Assuming the disk was long gone, I took a few photos of the area to document the note and made a mental note to perhaps come back later to take measurements. As I was leaning in to take a closer look at the possible stem remnant, something caught my eye - a disk about a foot and a half away from the concrete monument. I picked it up and saw "ESSO STANDARD OIL COMPANY BENCH MARK" inscribed on it and said "Whoa!" (or something like that). The datasheet shows a good recovery in 2014, so apparently the damage had occurred recently. The disk has many scrapes on it so it appears to have been hit several times. As I was standing there several trucks made the turn at the intersection and came uncomfortably close: So I figure a truck made the turn really close, scraped over the curb and sheared the disk off the concrete monument. I pocketed the disk and now it sits on my desk. Questions: What to do with the disk? I'd love to keep it as a souvenir, but should I contact the state highway administration and see if they want it back? Is there any value for surveyors having the disk back? I've read that the stem remnant can still be useful; is it more so with the disk? Would they reset the same disk, place another, or not do anything? Do other companies have their own disks that are included in the NGS system? And why would the MD SHA monument a mark using a private company disk? Is this worth my filing a report with NGS? I've never done one before. Finally, should I log this as a "Note" or "Found?" Thanks in advance for your thoughts and input on this. Brian (ipuppy) Quote Link to comment
