We do this from time to time here on the ‘Dope, and it’s a slow day at work, so…
Furthest North: London, England, UK 51°30’26” North. I’m not prepared to say what specific spot in London was the furthest north, so I just went with London generically.
Furthest South: Some rainforest within half an hour’s drive on San Juan, Puerto Rico, USA 18°24’23” North. That’s the latitude Google gives me for San Juan generally and not the specific place where I went ziplining.
Furthest East: Tokyo, Japan 139.7° East. Again, I don’t know specifically where in Tokyo.
Furthest West: San Francisco, California, USA 122.4° West, I don’t know specifically where (doubtless Alcatraz Island).
Note that being on a plane in the air doesn’t count, else much of this list would be “somewhere near the North Pole” for a lot of Dopers.
West: We sailed to just off the coast of Ethiopia but did not go ashore. It looks like Bangkok was the furthest west I was on land, Singapore & Pattaya Beach just behind it.
North: It appears to be Lossiemouth, Scotland on my Honeymoon. We did 17 days driving around Scotland and staying at B&Bs. It the next few years we should get to Iceland.
East: It looks like Toulouse, France edges out London and anywhere in Scotland. Hopefully in the next few years, the west coast of Italia.
South: On land it looks like Singapore, at sea, somewhere in the Indian or Pacific Ocean. We sadly did not go to Australia.
South: 10.23 N near Tamarindo, Costa Rica
North: 64.94 N, just above Fairbanks Alaska
East: 6.58 E, Aalten, Netherlands
West: -150.12 W, Talkeetna, Alaska
As to Ethiopia, it was not land-locked when I was on West Pac. Eritrea broke off in 1993. No idea what port we where going to. I was in for the part of the 80s.
I see. I think the OP was asking for the most extreme lats and longs according to the map, not distance traveled in a certain direction. What would yours be by that standard?
Pretty far, but some just recently despite a long era spent traveling smaller ranges.
N: Last year I went on an arctic Norway cruise that was supposed to land as far north as Tromsø @~ +69.6 +18.9. For weather, we never made it that far north and instead turned back at Trondheim @~ +63.4 +10.4. At Tromsø we’d have broken the Arctic circle. At Trondheim we did not. Missed it by ~3 degrees. Arrgh! My previous record was a bit north of Anchorage Alaska @~ +61.6, -149.1
E: Gisbourne New Zealand @~ -38.6 +178.0
S: Until recently had been Christchurch New Zealand @~ -43.5 +172.6. But I just got back from Antarctica, so scored going ashore in Neko Harbor @~ -64.8 -62.6. Missed the Antarctic circle by ~3 degrees. Double Arrgh!
W: Kauai Hawaii @~ +22.0 -159.6. I’d also visited some islands in the western hemisphere South Pacific, but Hawaii is surprisingly farther west than they are.
Other than touring North mainland Alaska and along the Aleutian islands I don’t think I can break my North, West, or East records. Could go to Tromsø by air or land to break the North record, but with Alaska being a three-fer that probably won’t happen. Getting farther South is gonna be tough too.
How arbitrary and senseless, but by that standard.
Somewhere on Oahu, Hawaii let’s go with 21.58 by -158.16 West
Sasebo, Japan is probably my East then. 33.16 by 129.73 narrowly beating out Busan, S. Korea 35.05 by 128.96 and Subic Bay, Philippines 14.80 by 120.28.
North: Somewhere in Ireland. Probably Knock, or so?
South: Matamoros, Mexico
East: The coast of Maine
West: Somewhere in Washington State, near Seattle
If that’s the standard, and @What_Exit got to Ethiopia by going west, then he must have crossed the 180º longitude line at some point, which would therefore be both his easternmost and westernmost points.
