Well FrostG1anT, Islamorada and I were in the area of this benchmark (uw7564) and I figured we could try finding it. Mainly because its a very old one and not been found. BUT I'm not quite sure what we actually found. So here is what we found, could we get some advice on if we found the station mark or just the reference marks. this pic is of the first point that we found, notice it looks like a pipe about a half inch in diameter concreted into the stone. this pic is looking west toward the second point we found, it's about 71ft. away from the first. It's by the metal detector. this pic is of the second point that we found. It also looks like a pipe about a half inch diameter. this pic is looking from the second point to the first point, you can't rally see where it is because I didn't leave an item by it, but its in the center of the pic at a high point in the rock. I am facing east. this pic is looking across the second point toward the vegetation line to the north about 35ft away. After thinking about the placement of these points it's possible that the first point we found is whats left of reference mark 3 and maybe the second point we found is whats left of reference mark 4. I know I didn't give a very good explanation of this but I'm trying. Here are the coords for the points we found maybe it well help. First point (rm3?) N60 55.560 W149 21.771 Second point (rm4?) N60 55.563 W149 21.794

To make sense of what you've found (which looks like the stem of the marks - possibly) I'd have to go to the original datasheets and lay out the geometric relationship on paper, then take it to the field. Pulling a metal tape from point to point and checking the compass bearings would establish beyond all doubt what you've found. Scobey & I hope to do just that later this summer. You did well finding them at all! Did the metal detector help?
Of course, its also possible that you've found tie-downs for the boats and barges that used to travel Turnagain Arm prior to the 1920s. There's old 'staples' and ring-bolts scattered up and down the Arm on these type of rock outcrops. For example, on the rocks below a certain Scobey cache that looks south to Burnt Island there are a half-dozen metal tie-downs at & below tideline. In the case of what you've found, however, the one stem is hollow - which makes me suspect it's the stem of a mark.

I figured it might need another close inspection to figure it out. We defenently wouldn't have found what e did if not for the metal detector, they blended in very well. One thing I did is test the posts with a magnet and it didn't stick. After I scratched one to see what color it was it looked like brass or copper. I was thinking that if it was the marks they probibly got sheared off durring the winter ice flows. When you do go down there I would love to tag along and see how its done the right way. I have 4 or 5 extra metal detectors if there needed to cover the area. Thanks for the help. later.

Oh yeah - if they're nonferrous then they're the stems of the marks! Now to just figure out which ones, eh?
We'll include you in the journey. Besides, there's the small matter of that cache final I still need to do down there too.

I spent the afternoon on Bird Point with the family and concur with Malcore's findings. There are definitely the stems sans brass tablets still in the rock outcrops that are most like RM3 and RM4.
I did not find the original drill hole with a lead plug, nor did I find RM1 (a cross cut in the rock) or RM2 (a triangle cut in the rock). Of course, I was distracted by trying to keep two kids and two dogs from running too far into the mud or falling into a tide pool.
The 1964 field notes also refer to a triangle blazed tree which we also didn't find. The curious thing to me is that RM 3 and 4 are tied back to the tree, which would be a fairly transient object, relatively speaking.
It certainly would be fun to put all the pieces together on this one!

Im glad you were able to find the marks that we found. It would be fun to find all the marks on this one. It does have odd references using the tree and not the benchmark. Only reason I can think of for that is they realy didn't find the mark as they stated. Mysterys abound.

NorthWes, not sure if you found a certain cache down that way yet but I know I would love to tag along if you haven't done the leg work on this one yet. Now that the weather has melted most of the snow down low the area is getting more use. I need to get the same cache. Along with some BM's and Caches further south along the bike trail from here

Along with some BM's and Caches further south along the bike trail from here No I haven't recovered that cache or the benchmark(s) out there either. Hmmm... will need to navigate some reefs and shoals on this setup. I'll be back to you...

I still want to go back there and see if these BM's can be figured out. Maybe we could talk our resident Benchmarking expert (hint hint) into having a impromptu training course and realy show us all how this is done.

Would make a nifty road trip - there's some fun ones along Turnagain Arm around to Ingram Creek we could do, as well as the Bird station. Into the planning pot it goes...

I want to stir the pot and tag along too!
