Lochan Deo - a small quarry reveals the sediment inside an esker. It includes pebbles of both granite and schist. Bedding is developed but only crudely.



Eskers at Rothiemurchus

Rothiemurchus contains large areas of terrain shaped by meltwater flowing from the southwest. Good examples of eskers, kames and meltwater channels can be seen. Detailed geomorphological maps of this area are available (Young, 1974). The topography reflects deposition in the later stages of last ice to occupy Strath Spey. Ice moving down the strath flowed into the Glen More basin, with some ice escaping via Ryvoan. Huge volumes of meltwater flowed in tunnels beneath and within the ice. These tunnels became clogged with sand and gravel carried in the turbulent waters. As the ice melted the sinuous esker ridges were left as casts of the former ice tunnels. These parallel ridges are widespread beside Lochan Eilean.
