This shows Glyder Fawr beyond Castell y Gwynt, with the top of Y Gribin to the right, and Crib Goch, Snowdon and Crib-y-Ddysgl on the left:

👍Yes - well done, John!
I made it more difficult by cropping Crib Goch out of the photo!

Snowdon and Crib-y-Ddysgl from Glyder Fawr.

One of the mountains on the skyline is Crib-y-Ddysgl, but the other is not Glyder Fawr.

Helvellyn40: 😂

I'v looked at the map until i'am cross eyed, can't make anything fit,but will come back to it, although i suspect John will get there first.

That's a very good attempt, but not quite right. Crib-y-Ddysgl and Glyder Fawr do feature in the answer.

Guess Glyder Fawr and Crib-y-Ddysgl from Y Gribin
