Grand Prismatic?

Yes it's another one!* I lifted it from its position amongst flowers in a wall top garden I was passing on the main road and it said 'Bingley Rocks' underneath.
Another kindness stone. I really like the design on it, reminding me of the Grand Prismatic Spring in Yellowstone N P.

After church coffee morning I walked up through the village to feed my son's fish. It was on my walk back down that I spotted this. I'm on the lookout now.
