Upper Erme

Sinuous alignment ascending the hill at Dry Lake Ford. View from the south.

The longest prehistoric stone row in the world is of the single type and  measures 3,386m long, including around 922 mainly medium and small-sized stones together with some large orthostats situated in the Erme Valley. The row, which is sinuous in character is orientated north to south has a sea view reveal and visual links to the landscape.  There are cairns at the both ends, the one at the south is kerbed and the upper one at the north is surprisingly small and nondescript. The row passes through a landscape rich in prehistoric archaeology.

Sea Views

The sea is visible from the northern end of the stone row. Viewshed analysis originally identified this visual relationship and Neil Mortimer has kindly provided the fieldwork evidence. A photograph taken by him from the cairn at the northern end of the row shows two slivers of sea separated by Stalldown on which Hillson’s House cairn can be clearly seen on the skyline. The point at which the sea becomes visible is not currently known but it is likely to be near to the end of the row and the siting of the terminal point is likely to have been influenced by the sea.  It feels as if the row is seeking a sea view and once achieved it happily stops after its marathon journey. This row provides further evidence for a relationship with the sea and in turn contributes to our appreciation that the rows were often intimately linked with their landscape.

In places the row is completely buried beneath deep peat. At this point (SX 63688 65399) a stone is exposed and illustrates the considerable depth of the peat. This exposure provides an opportunity for environmental and dating analysis. View from north (Scale 1m).

The stone row passes Erme Pound which is a prehistoric enclosed settlement which was re-used in the historic period.

View from the cairn at the northern end of the row. The kerbed cairn at the southern end of the row only becomes visible when the northern cairn is reached. For much of the row the kerbed cairn cannot be seen appearing only at the point where the row stops. This precise visual link is likely to be significant.

Only part of the alignment (highlighted) is visible, but from this angle its sinuous character is very obvious. 

Two rows or one?

A consensus exists that this row is a single site albeit split into segments by the River Erme. Certainly when walking along beside it it forms part of a single route. The only problem with this interpretation is that at SX 63688 65725 near to the River Erme the row suddenly becomes a double row and stops.  The position of these stones in the valley bottom is problematic in itself as the valley bottom has been streamed for tin and therefore one would not really expect any stones to survive at all. This said, the scarp denoting the edge of the streamwork in this area is unclear and it is possible that at this point the row has survived. Unfortunately time to investigate the situation was not available and a return trip may be necessary. Assuming that the short length of double row is original it could be argued that this represents the southern terminal of the northern length. Tempting whilst this idea may seem we need to remember that combination rows which consist of both single and double lines of stones are known on Dartmoor and indeed at Drizzlecombe 1 the double length is found in the middle of the row. For the moment it would therefore seem appropriate to think of the row as one structure, although future work might mean that this conclusion needs to be reviewed. Given the short length of double row it is perhaps best to think of this site as a single rather than a combination row.

Access Information

This has never been an easy row to get to. When visited in 2013 car parking was available at SX 62524 61120. Recently (2016) this car parking area has been closed making it much more difficult to access this part of the moor. An alternative car parking location is at SX 64342 59548. From here the easiest way to reach the row is probably to head east to the Two Moors Way at SX 65765 59965. Then follow the track north to SX 64683 63454. From here navigate north west taking care when crossing the River Erme. Given the effort to get to the area it would be a good idea to have a look at the Hook Lake Row and if you have time the splendid one on Stalldown as well as some the amazing prehistoric settlements.  Another option maybe to park at SX 60395 70806 and approach the row from the north via Crane Hill. A full day but hopefully a rewarding one. Best contemplated in the summer.
