Is this possible?

Last week we walked up snowdon and were treated to some epic clear skys...

]

I'm thinking the visibility was touching 70 miles. Is this possible?
The island in the far right on this shot is Bardsey Island, 40 miles away.

This 100% crop shows land in the background (IMHO

), finishing to the left of the taller hill.

I know that hill to be Moel Hebog and the sandy coast area to be just south of Porthadog. Using the power of memory map and some guess work it looks to be 70 miles to that land! :eek:

What do you guys think?

Yes it is possible and the top pic is a really nice shot. What camera did you use?

Thanks! 30D

Fantastic weather for the time of year

You can see Ireland from the summit on a clear day, Isle of Man, Blackpool lights, rare to get a clear day mind

by random coincidence similiar shot from a game engine I was working on... (the view point was from the top blue arrow on the map above give or take)

Looks like the terrain scale in the engine is ridiculously out compared to the real thing.

Definitely possible to see 70 miles, especially at altitude.

At open sea (or very flat land), a 6 foot (1.8 meter) man can see an object on the horizon at 12 miles, although some will argue this is as low as 3 miles and as high as 17. I personally can testify 12 miles is about the right distance to be able to see the bottom of the object.

Once you get higher in the air, it is easier to see much further before touching the horizon.

That first pic is beautiful and I would definitely agree it is a clear 70 mile shot. You can almost make out the curvature of the earth in that.

You can see the Isle of Man hills from the top of Scaefell Pike:

(the day was still a bit hazy, but they are the jagged bits poking up out of the clouds slightly right of centre.)

Awesome pic's. Cant belive you can actualy see that far!

The view from Snowdon is marvellous isn't it? One of the finest in the UK for sure.

Took that in Sep last year, some more on my site of the mountain and Conwy too:

It really is!

We did Ben Nevis last year and had to give up less than 150 meters away from the top (and it’s flat by then!) The cloud was so thick you couldn’t see where it stopped and the snow started.

A guy had walked off the edge the weekend before because he couldn’t see it!

Definitely possible - on a clear day, I can easy make out the mainland, and even see the glints of reflection from a car window in the sun
