Geocache Description:


The co-ordinates at the top of this page are not those of the cache. A two-stage multicache, with rough trails and upland hiking involved. Please dress appropriately for mountain walking where the weather may change suddenly. Expect very wet ground underfoot at any time of year. Just under 9 Km (round trip) from the given parking place.

This cache route takes you on an easy walk through some of the most impressive scenery in the high Mournes. From Stage1 (see below) the route descends along the line of the Miners' Hole River towards the Silent Valley reservoir.

Near the final cache site this stream drops over a rock shelf, forming an attractive waterfall. The fall marks the postion of a significant NNE/SSW fault line in the underlying type 3 granite, and it was along this discontinuity that miners of long ago thought they might find mineral deposits, including perhaps tin or lead.

Despite a great deal of research, it has proved difficult to find any definitive historical information about the origin of the Miners Hole.

In his classic work Mourne Country, Prof Estyn Evans states that it was cut by Cornish tin miners employed for the purpose, but gives no date for their activities. The most likely period is the late 18th or early 19th centuries but how many men were involved, or how long they spent prospecting in the Mournes, is no longer remembered.

The experiment was not a success, and the Miners Hole remains no more than that to this day. An examination of the deposits around the hole will still produce silver coloured flecks. Unfortunately these are not silver but an iron compound.


Parking: The most convenient parking place is at the south end of Bann's Road, at N54 07.542 W006 02.160


An alternative authority, Luke O'Zade, contributes the following -

"The earliest evidence of mining activity in the Mournes is to be found on the slopes of Slievnamiskan, to the west of the Spelga River. Here, tin was extracted during the Early Bronze Age and alloyed with copper to make bronze. The nearest source of copper was in the Wicklow Mountains, far to the south, and transportation delays resulted in the Early Bronze Age in Ireland becoming the Slightly Late Bronze Age.

Some time after this, further thin deposits of tin were found in the clints and grykes of the igneous dykes and this story reached Lord Kilmorey, who promptly applied for a poetic licence on the strength of it. He sent for a gang of unemployed tin miners from Cornwall - large parts of which were at that time owned by his brother-in-law and still are. Unfortunately, Kikmorey didn't own the land round Slievnamiskan but, nothing daunted, he set his willing crew a-digging round the north side of Slievnaglogh instead.

After a full summer's prospecting the Cornishmen had found nothing, but kept mining anyway as they needed the money. Prof Evans suggests (op. cit.) that this ligging digging resulted in the area being named "Happy Valley", though where he got such an idea is anyone's guess. After improving the shaft to some six metres in length (during season four) the miners broke through into a vast subterranean aquifer which spilled out and flooded the whole place, forming a large reservoir. This was renamed the "Silent Valley" as no-one would admit having caused the disaster.

Following this debacle, Lord Kilmorey became a recluse and devoted himself to the breeding of ferrets. The miners were all laid off and had to sign on the buroo in Newry, where many of them remain to this day. The memory of their failure still rankles, however, and no further exploitation of Mourne's rich mineral wealth has ever been attempted."


Stage 1: There is a stone-built bridge here. Find the four-digit number inscribed on the masonry (this is where it earns the difficulty rating), let the digits equal A B C D respectively, and apply the following formula to get the final coordinates:

N54 09.A0(A+B) W006 00.C3D

Date check. A+B+C+D=15

Final: A tab-lock box 25x15cm is hidden at ground level. The Miners' Hole is on the opposite side of the river from the cache. Please ensure that the container is not visible when re-hiding it. This cache is not recommended for Travel Bugs as it is rather remote, and may not see much traffic during winter months.
