On to the bay side of Skaill House to try and locate the Knowe of Geoso. Even using the map I had a terrible time finding my bearings, as if the two regions of paper and land held only the flimsiest of connections to one another. Walk to the edge of the far house wall corner and look across uphill. It is easy to see the triangular scar of quarrying in the top right corner of a field. The cairn is just by the top right corner of the field diagonally opposite (though outside of it a fraction). Might have made it out on the horizon from here, wasn’t sure. Spent so long thrashing out my bearings making my way through fields of cattle to it felt beyond me. Saw drivers going to Skaill House Farm, which looked a simpler option, but making the grand detour to get onto that road in the time remaining was problematical. So I gave up for now at least.
