Tin mining is an ancient industry in Devon and dates back to pre-Roman times. Along with mineral extraction, Tin mining has been a key industry for Devon from ancient history up until the twentieth century.
Although most of the mining in Devon has focused on Dartmoor, with tin frequently being found in areas of granite, many adits were dug into the Exmoor rock in exploration of ‘whatever’ could be found and mined! It is through one of these adits you must venture in order to find this cache.
The co-ordinates above are for a start of a rocky track that leads down to the adit. This area contains a number of tunnel entrances and in order to obtain the co-ordinates for the one with the cache in, you must first solve the following puzzle:
N° DGFAC CBBCD EFAAG DBCEF FDECA BBCGF FAGCD
W° ADFBE CCEBF DAAGD BCCFG BBCAA GDBEE FDCGG ADBE
You can check your answers for this puzzle on Geochecker.com.
The adit opening is well concealed and quite small (check photo), but once inside the tunnel there is room to stand. The first 'section' of the tunnel is filled with ice-cold water, so be sure to bring appropriate clothing.
