Cyclist, Does anyone know what these wee lumps are? I see so many of them on coastal walks around #Scotland. Always on the skyline and near the top of grass-covered rocky outcrops. They seem to be similarly sized - a few inches in diameter and a few inches high
I've asked plenty of people who are generally knowledgeable about nature, but none of them know what causes them. Some interesting speculation, though
