There is much more stone at the Toot end in recent years, in my opinion due to the commissioners raking the the beach, over the past few years they have transported tons of sand from the Toot end to the Cosy Nook end using a digger, tractor and trailer, I used to live on Port Erin beach in the mid to late 50's, and I don't remember any stones between the stream and and the flight of steps at the Toot end, we had to cross over the stream to get stones to decorate sandcastles.
