[Travel] Interesting maps

[Worried Man Blues]

I think the north pole being at the south pole that recently has more to do with it occasionally flipping over altogether, rather than it's gradual shift across the Arctic as illustrated by that map.

The flipping polarity leaves bands in the rocks in the Atlantic, which I was hoping to illustrate with a thread-appropriate map, but I couldn't find anything that looked remotely clear or helpful on the back of a quick Internet search.

Other fun north pole related fact, Polaris is gradually moving across the sky, so back in Ancient Greek/Roman times it wasn't exactly above the north pole, and in a few hundred years it'll have moved past it.

Wiki says it's gradually moving...........As of early 2019, the magnetic north pole is moving from Canada towards Siberia at a rate of approximately 55 km (34 mi) per year.[ Personally I haven't a clue!!

the magnetic poles have always moved, basically oscillating "left and right" . In order to read maps correctly you need to take into the account the difference between true north and magnetic north. To be entirely accurate with a map and compass you have to allow for the difference and add or subtract the difference

This changes with time but is different from when the poles flip

he difference between True North and Magnetic North is as follows:

• True North is the geographic North Pole, aligned with the Earth's axis.
• Magnetic North is where the Earth's magnetic field points vertically downwards, and your compass points towards it. It varies over time and location due to changes in the Earth's magnetic field123.
• The difference between the two is referred to as Magnetic Variation or Magnetic Declination4.

Flipping magnetic poles, also known as geomagnetic pole reversals, have happened throughout Earth's history123. The last one occurred 780,000 years ago2. These reversals take a long time to occur and pose no immediate threat2. The Earth's magnetic field is in continual flux, causing the location of Earth’s magnetic north and south poles to gradually shift and even completely flip locations every 300,000 years or so3

I prefer a good old fashioned real one, with my mates Ordnance and Survey.

I used to, but now I can flick through all the pages on line without having to lick my finger!

This amazed me...the Magnetic North is moving and always has! It used to be at the South Pole in the mammoth era, mucked up their migration I presume!!

You'll have missed this then. In the world of those of us who work with maps on a daily basis, it was quite an event!

Three ‘norths’ combine over GB for first time in history | OS

November 2022 saw geospatial history being made when true north, magnetic north and grid north combine at a single point in Great Britain for the first time ever.

The OS Maps app is the app I use the most on my phone, by far. Great for planning and recording walks, as well as making them up as we go along. Also great for following (UK) travel documentaries.

The NLS side-by-side maps are brilliant for family history, pinpointing where my ancestors lived. Google maps also has its place for that, but is rubbish for hikes.

Queen's Park Cricket Ground. An obsession of mine. No pictures exist. Only a couple of references. How it was even level is something I can't work out, given the uneven terrain as it is now.

Looking at that it was on the site that is now St Luke’s church opposite the Beaufort Pub
Very interesting map thanks for posting

I love a little map of Africa

Oh yeah, it's definitely moving (as other's have also replied with since), it's just that's a different thing to the north magnetic pole sometimes being at the south geographic pole.

Yes, I've lived in the area most of my life. I used to pretend the back garden was a cricket pitch- and then found out it once was

Thanks for this, last time I had cause to navigate with OS Maps the difference was I think 8 degrees (cant recall if east or west-it was a long time ago). This current alignment would make orienteering much easier for a short while!

I thought it was a bit Chile today. Now I know why.

I was at Peterborough station in 1986 for the FA Cup match. Possibly the coldest game I can remember. Almost ten years later I was at the Peterborough station above in South Australia. It was 41 degrees C
