Hyner Rocks

Hyner Bottom Rocks, Highner Rocks, Hyner Tor

A huge crag of rock juts from the steep valley side above Beadon Brook on the southern side of Canonteign Down approximately one mile to the north of Hennock right on the boundary with Christow. Known locally as Hyner Rocks (sometimes 'Highner') it consists not of granite but is composed of a distinctive type of shale that is peculiar to the area. A geological fault referred to as Hyner Mudstone runs to this point from Beadon Lane to the west.

Information on the location of this tor was first passed to Tim Jenkinson by Ian Parsons, as well as being documented by Dr. Peter Sanders back in 1996. More of the rocks extend downhill into Hyner Bottom where a delightful mini canyon is formed either side of the brook. Mining operations are evident here along with artefacts such as an old wooden launder on the south bank.

The Rocks can be easily reached by a good woodland track leading up from Beadon Lane and then descending a short distance through trees and gorse to the summit rock where exhilarating views to the south are enjoyed, all of which currently reside on Public Access Land.
