Blue Biggs Jasper stone. Blue Biggs Jasper is a silicated volcanic ash. It was formed during a volcanic eruption and is part of a Miocene series of rocks called the John Day Formation, near Biggs, Oregon, USA. It is a decorative stone used for jewellery and trinkets.
I love the natural feeling Andy has gave this picture. He has broken rocks almost perfectly through the middle to create a path. The white layer near the crack also make the picture even more appealing.
St Micheals mount, Penzance. Cross the crossway at low tide and explore the castle and its beautiful gardens. Legend says a giant threw the rocks into the sea in anger. Just make sure you time it right on the way back. The tide races in fast and can cut of the unwary walker, so take one of the many boats back
Having discussed with the builder I think we can achieve a more gentle climb to the top using a mix of sloping paths and steps on the lower level. Would be sleeper and aggregate/bark materials rather than gravel which would be a pain with the lawn.
