The River Holford is located in the east Quantocks hills Area of Outstanding Natural Beauty in Somerset.
It is approximately 4.5 miles (7 km) long. Its source is at Lady's Fountain Spring, Frog Combe ST150384 which is near Halsway and 250 m above sea level[1] before flowing past Holford towards its mouth at Kilve ST143444.
The river is used as an outdoor classroom for students of Fluvial Geomorphology.[2]
The geology of the river consists of three different rock types at the top of the river there is the Devonian Quartzite(Metamorphic), in the middle of the river there is the Permo-Triassic Marl(Sedimentary) and the lower part of the river consists of Jurassic Limestone(Sedimentary). The first two rock types are impermeable meaning there is little drainage for the river but the river depth becomes smaller as the water flows of the permeable limstone which will allow water to pass through. Quartzite is also very resistant to chemical weathering and can form ridges.
