1) the first chart of Wikipedia entry for Elephant Island has three small points on the northern side of the eastern end of Elephant Island. The western most of the three has no name, the middle is the modern Cape Belsham, the eastern is denoted Point (Camp Wild)

2) Chart 29104, http://fer3.com/arc/img/137966.20170126_011725.jpg is the most up to date, listing sources to 1997, post dating the joint services chart by 27 years. It has three small points on the northern side of the eastern end of Elephant Island. The western most point is identified as modern day Cape Belsham, the middle Point (Camp) Wild and the eastern most with no name.

3) Joint Services Expedition 1970 chart has three small points on the northern side, eastern end of Elephant Island. The western point is un-named, the middle is modern day Cape Belsham and the eastern is Pt (Camp) Wild.

4) The coordinates 61°06'S, 54°52'W for Point Wild given on this Wikipedia page, using 29104, places you right on Point (Camp) Wild on Chart 29104. Those are the coordinates of Point Wild, per 29104

5) the location of the monument which Robin argued from photos appears to be on the easternmost of the 3 promontories. Robin, you agree with (1) and (3) but not (2) and (4).

I do not wish to make a mountain out of a molehill. All three points are within 4' of arc, or just under 2 nautical miles from Point 1 to Point 3, with Point 2 roughly in the middle.

At most, we shift the location of Camp Wild 1' of arc east or west, with a variation in time of 4 seconds. That's not really worth disputing.

If I had to choose 1 definitive map, it would be 29104. It is part of Portfolio 290, Weddell Sea Antarctic Coast to Princess Martha Coast, consisting of 17 charts overall. I have the complete set. It's what navigators in the Antarctic use today. I have paper copy, so there may be an update.

Brad,
The Wikipedia page you reference Wikipedia entry for Elephant Island has 2 maps on it. The first is consistent with Chart 29104 but the second is not. Nor is Chart 29014 consistent with the Joint Services Expedition 1970 chart which you had posted. Nor is it consistent with the coordinates 61°06'S, 54°52'W for Point Wild given on this Wikipedia page or the location of the monument which I argued from photos appears to be on the easternmost of the 3 promontories. Please take a careful look at the cropped images I attached to my post http://fer3.com/arc/m2.aspx/Updated-Transcript-Worsleys-Log-Stuart-jan-2017-g37975 and you'll see 2 instances of each possible placement. It seems to me that Chart 29104 has it wrong! Please let me know if you agree,
Regards,
Robin
