Barnhill Rock Garden is sited on part of a former nine-hole golf course that was laid out after the Dundee to Aberdeen railway was built more than a century ago. When the Esplanade was constructed in 1895, the course was established, on advice from golfer Tom Morris, with four holes west of Bridge Street - now the Rock Garden - and five holes to the east. The course was completed in 1896 and cost a grand total of £80. The last visible reminder of the course, the former clubhouse of the Broughty Ferry Ladies Golf Club, was demolished following a fire in 1993. The garden was started in 1955 by clearing an area of volcanic rock that had at one time been the old shore line. Over the years it was extended eastwards over areas that had been sand dunes, and rock from Carmylie Quarry was used to form a large part of the garden. There were originally five natural springs and the lowest pond is the site of one of these, the others having dried up in 1976. The lower ponds were created in 1982 and the upper ponds in 1985 and have separate water circulating systems. Plants have come from many sources. The Friends of Barnhill Rock Garden have donated seeds and cuttings and the Scottish Rock Garden Club and Dundee Botanic Garden have also made generous donations to create a "geographical" theme to reflect the many countries from which the plants originated.
The actual cache is a Magnetic Film Canister with log and pencil at: N 56° AB.CDE W 002° FG.HJK 
The missing digits for the co-ordinates of the cache location can be found on some of the Rock Garden's benches. Many have plaques, commemorating a wide range of people who enjoyed the peace and tranquillity of this little horticultural treasure. The following clues to the missing digits need the information from a variety of the plaques. The benches are not in any particular order, and not all benches are involved, but your search will take you to almost every nook and cranny of the garden – so enjoy the Rocky Road!
A: The digit used most on Sydney and Wilma Binks plaque?
B: The difference between the sum of the digits of “Chuck's” birth year and the sum of the digits of the year he passed away.
C: Anne lit up every room she entered: Multiply all the digits of her final year.
D: Edith was obviously very special. The sum of the first and last digits on this plaque
E: Graeme loved Broughty Ferry and spent his whole life here. The sum of first three digits of his birth year, minus the last?
F: Ian, now “dancing in the moonlight” with Dorothy, was born in 192F
G: Tracey!! How many??!!
H: Robert Cathcart came into this world in 19L7
J: The difference between the first and second digits of the birth year of Yvonne Alexander
K: Jean Russell Simpson: The difference between the digits for the day she came into this world and the day she left.
You've taken the Rocky Road – so now enjoy a bit of Reserve as you head to:
N 56° AB.CDE W 002° FG.HJK
Careful, this is a popular local area for walking, so could be a few people (and dogs) around.
