Old Mark Not On Gc.com

Occasionally, I will run across an old mark that is in the NGS Databse but not on GC.COM. Case in point, BL1600 , monumented in 1954.

 

I can't figure out what is going on. Was this mark not publishable when gc.com got their cd's? Did gc.com filter it out for some reason? Was it their former practice to delete a mark from gc.com if it was reported as destroyed here? I went to look for this mark, and it was almost certainly destroyed by widening of the road, possibly after gc.com was started.

Terra,

 

When a road is widened, and the widening is along side a ditch or deep waterway, we dig a new channel for the waterway, move the water to it, close off the old waterway and de-water it. Then we remove all the Topsoil, muck, organic materials. As we go we also remove the man made bridges, culverts headwalls and other structures in the area we intend to fill in.

 

Filling in requires that once all the structures are removed and the unusable soil is removed down to structural Material such as Original ground less topsoil, we then begin filling the ditch with a structural fill material that meets quality standards and it is compacted to the right amount of compaction that the engineers have determined adequate for that soil type. After that, utilities may be placed in the new fill, and the road widening with perhaps concrete curbs, sidewalks, signal control, street lights and asphalt paving.

 

Every detail is built to surveyed accuracy.

 

If the road was widened and the headwall was removed to facilitate this, then there is the demise of your station. If you like, you could send a note of not found to NGS detailing the lack of a headwall and a widened road. It would save someone from wasting time on it in the future.

 

If for some reason the mark was not considered publishable during the time that geocachings copy of the database was being distributed, it may have been left out of that version of the database. We find things like these more often than you may think. NGS has track on many stations it does not currently publish. It is doing maintenance on the data all the time.

 

Good Luck, Hope that helps.

Interesting. So you have seen cases where an individual mark has gone from Publishable to Non Pub and back to Publishable?
