Jim, I have trouble understanding how those trees on the right could mask not only the RR tracks but also a right of way and a RR station if these things were only 360 yards away and 50-70 ft below. I also have trouble understanding how that photo could be overlooking significantly lower ground. If the camera was level, then everything along a horizontal line across the center of the photo ought to be at the same elevation as the camera -- in this case 150-160 ft above sea level. If that photo with the man was taken from the third then the camera is angled significantly downward. From the position of the man, I am not sure that that this is the case. That said, you have been there and I haven't, and maybe if I had been there I would understand.
As for Bryan's description of where we agree and disagree, he wrote that the absolute elevation issue is a "red herring." But the elevations on 1913 map are NOT a red herring when we are trying to compare to elevations not depicted on that map, and this is exactly what we were trying to do in that particular discussion. Bryan knows this and has acknowledged it, so I have no idea why he keeps indicating otherwise.

Bryan, You are increasingly treating
elevation above sea level as some vague and amorphous corner of science where everything is up in the air. This is hardly the case. Science can determine elevations to within a foot using lidar technology, and such readings have been taking on Pine Valley's site. While the data set isn't great, and isn't much good for comparing relative elevations on the site. It does provide enough information that when combined with every other data set we have, it leaves no doubt about the accuracy of the 1913 data.
As for your implication that even sea level has been in flux enough to impact the measures, according to a few online sources, sea level rose by about 8 inches last century. Not static, but certainly not the reason the 1913 numbers are off either.
Also I think you have twisted "absolute elevation" well away from how I was using the phrase. I was simply drawing a distinction between the
relative measures within the 1913 survey vs. the actual measures as compared to the accepted benchmark of sea level, to point out that even if the relative measures are accurate (we don't know this) the entire data set could be off as compared to sea level. This appears to be the case. One need not determine the elevations on the site to
zero error to know whether the 1913 site is accurate. And one one need not have perfect correlation between the various USGS surveys. But outside the vitriol of this discussion, I have no doubt that we would agree on this issue.
If we took five measures of the height of a man using various methods and technologies, and the heights were 5'11 1/2", 6'0", 6 1/2", 6'1", and 6'9", would you make no assumptions about the accuracy of the last measure or the height of the man?

As for your latest comments about Brauer, you baffle me. Brauer had the last word and I let it go, without response. Yet here you are again not only bringing it up but ripping me for not letting him get the last word, and claiming that it is me that won't let it go? Perhaps it is you who won't let it go.

Regarding my questions about the third tee, you wrote:
I think it's possible that this picture is pointed in the opposite direction, so this discussion is moot.
Why, when you do not like the answer to my questions, do you declare my them "moot" or a "red herring?" Do you really think that just because you think it
possible that it could have been from another angle, my questions are irrelevant?
As to your theory about the camera facing the other way, as Jim points out the background looks to be the same as the photo supposedly from the 6th ridge. Which brings me back to my questions . . . .

As for your requests that I measure the photo and estimate the height of the trees, I think we've covered it all before, and don't want to get back into you quizzing me about my ability to to understand photographs. You never even bothered to answer my follow up questions last time we went down that road. Anyway, I am sure I posted the photo from the shelly book with a ruler so you can measure it if you like.
