Thomason Foss
Thomason Foss is a picturesque waterfall located on Eller Beck in the parish of Goathland on the North York Moors in England. This charming cascade drops approximately 12 feet (roughly 4 meters) over a broad sandstone ledge, creating a curtain-like fall that spreads across the width of the beck during periods of good flow. The waterfall is formed where the stream encounters a harder band of Middle Jurassic sandstone, creating a natural step in the watercourse. During wet weather, Thomason Foss can be quite impressive, with water sheeting over the rock face, while in drier summer months the flow may reduce to a gentler trickle across the mossy rocks.
Eller Beck is a tributary of the River Esk and drains the moorland around Goathland, flowing through this attractive valley before eventually joining the main river system. The beck gathers water from the surrounding heather moorland and pastoral landscape, and its flow can vary considerably depending on recent rainfall. The stream passes through ancient woodland in places, and Thomason Foss represents one of several small waterfalls and cascades along its course as it descends from the higher moorland plateau toward the lower valleys.
The surrounding landscape is characteristic of the North York Moors, with a mixture of moorland, improved pasture, and patches of ancient woodland. The waterfall sits within a wooded glen where oak, birch, and rowan trees provide cover, creating a sheltered microclimate. In spring, the woodland floor around Thomason Foss may be carpeted with bluebells and other wildflowers, while ferns cling to the damp rocks beside the falling water. The area supports typical moorland and woodland wildlife, including birds such as pied wagtails and dippers that are often seen along the beck, as well as various insects and invertebrates that thrive in the damp conditions around the waterfall.
Goathland itself is a well-known village on the North York Moors, famous for its appearance as "Aidensfield" in the television series Heartbeat and for its railway station, which featured as "Hogsmeade Station" in the Harry Potter films. While the village attracts many visitors, Thomason Foss remains a quieter attraction compared to some of the more famous waterfalls in the area. The waterfall can be reached by footpaths from Goathland village, typically involving a pleasant walk through the surrounding countryside. The approach usually requires crossing fields and following the beck downstream or upstream depending on the chosen route.
Access to Thomason Foss generally involves walking from Goathland village, where there is parking available, though visitors should be aware that the village can become busy during peak tourist seasons. The walk to the waterfall takes visitors through typical North York Moors scenery and may involve crossing stiles and potentially muddy paths, so appropriate footwear is advisable. The waterfall is located on or near private land, and visitors should respect the countryside code, keeping to established paths and being mindful of farming activities in the area. The walk is generally suitable for reasonably fit walkers, though the terrain may be uneven in places.
The name "Foss" is a common element in waterfall names across northern England, derived from the Old Norse word "fors" meaning waterfall, reflecting the Viking influence on place names in Yorkshire and the broader North of England. This linguistic heritage connects Thomason Foss to the region's medieval history when Norse settlers established communities across the uplands. The specific name "Thomason" likely refers to a personal name or a local family associated with the area, though the precise origin may be lost to time.
The geology of the area provides insight into the formation of Thomason Foss, as the Middle Jurassic rocks of the North York Moors create natural steps and variations in stream gradient that give rise to waterfalls. The sandstones and occasional bands of harder rock resist erosion more effectively than surrounding strata, creating the ledges over which streams like Eller Beck tumble. Over time, the action of water has carved out plunge pools and worn the rock faces, though Thomason Foss remains relatively modest in scale compared to some of the larger waterfalls found elsewhere in the North York Moors.
Visitors to Thomason Foss can combine their trip with exploration of the wider Goathland area, which offers numerous walking opportunities, including routes to other local features and connections to longer trails across the North York Moors. The nearby village provides amenities including pubs, tea rooms, and shops, making it a practical base for a day's exploration. The seasonal nature of the waterfall's flow means that visiting after periods of rain will provide the most dramatic spectacle, though the wooded setting and peaceful atmosphere make Thomason Foss an attractive destination in any season.
