Stanley´s second nano and first mystery cache, hidden 49 metres above sea level in Stanley itself and NOT at the listing co-ordinates: if you go there you´ll just find sea! There´s something interesting to see at the intermediate waypoint and also just down the road from the cache.
Wheelchair bound cachers might just be able to reach the cache without help but not sure; hence 1.5 terrain.
To find the information you need to work out the final cache co-ordinates you need to make your way along Stanley waterfront to the intermediate waypoint at:-
South 00101000010010000001001000001000111
West 0000000101001110010100001010000100100001
Look at the base of the pointy object nearby and use this to find the missing numbers in the final cache co-ordinates.
First look at the side where a dedication that mentions science is written.
a = the third figure in the date.
b = the number of letters in the sculptor Oliver’s surname.
c = the number of times the letter ‘a’ appears in the continent mentioned in the dedication
Now look at the opposite side where there a 2 maps and place co-ordinates
d = the total number of letters in the word before ‘Gateway’
e = degrees Longitude of the place at Latitude 52 degrees North
The FINAL CACHE is to be found at S 51 deg 4 (a) . (b) (c) (a) mins; W 057 deg 5 (a) . (d) (a) (e) mins.
Please make sure you replace the cache exactly as you found it & try and give it a bit of TLC if the log gets full You´ll receive “honourable mention in the listing” if you do!
My grateful thanks to JohnCFI for agreeing to help me maintain this cache if this becomes necessary (& if he can find it 
As it turns out the first people to receive the accolade of "Honourable White Knights of Geocaching" from this distant placer are CelticNomads. Many thanks indeed for putting a new container in place when the original seems to have been blown away in one of the gentle Stanley breezes. Your help in this matter is very much appreciated. (Seems a long time since we met up by the museum earlier in the year!)
And more thanks are due to 2Wagtails who put a new nano in place in 2019 when the old one appeared to have lost it's cap and then gone missing. I really am very grateful to you John & Laurel 
And the latest to help was MSquared - Morgan Marshall (normally around South Lake Tahoe, CA) who worked out the correct final H iding place but found nothing there in Jan 2023. After contacting me he hung a new bison tube in place for which I am extremely grsteful.
