At da Waas Boundary Fault

A really windy day, but really warm wind and in 20s degrees.  Sun has been shining and blue skies.  By 8pm rain started and mist on the hills.

The morning was spent around the house and walkies with Sammy.  Mam, bro Jonny and family came and picked me up at lunchtime, and we all headed north.  We've spent most of the afternoon with aunt Joan in North Roe, then a walk and onto Frankies for tea.  A quiet evening at home now, might head out with friends later. 

I took the family for a walk to the Walls Boundary Fault, none had been here before. The Fault is part of the Great Glen Fault system, a series of massive splits in the earth's crust that slices through the Great Glen of Scotland to Shetland.  The fault is so called because it forms the boundary of the Walls peninsula on the West of Shetland.  Rocks on opposite sides of the fault have moved relative to each other for more than 100km in a series of movements that caused massive earthquakes in the Devonian and Jurrasic periods.  This is the best exposure of a major shear fault in the UK.  Taken at the Back of Ollaberry.
