Didcot GeoCache Series
After our recently placed GeoCache Series at Great Western Park (GWP) (cache #1-11, 14, 17-19, 30-32, 35, 38, 60-61, 80-81), Didcot (cache #12-13, 15-16, 20-25, 29, 33-34, 41-42, 44-45, 47-48, 53, 59, 62-63, 66-67, 69-79, 82), Harwell (cache #26, 36-37, 43, 46, 54-55, 58, 68), Chilton (cache #27-28), Sutton Courtenay (cache #39, 64-65) and Milton (cache #40, 49-52, 56-57), we decide to place a few more caches in other parts of Didcot and surrounding villages, in order to honour local heros, and to reflect our rich local history, stories and heritage. We hope you will enjoy these new caches and may also learn something new when you are caching, thank you!
Didcot #83 - Ladygrove Powerlines No. 2

Photo by Jonathan Rawle
The Ladygrove powerlines are high-voltage electricity transmission lines and associated pylons that run through the Ladygrove housing estate in Didcot, Oxfordshire.
Key Details
Location: The power lines cross the Ladygrove estate, a residential area home to around 7,000 people, radiating from the former Didcot Power Station site.
Local Action: In March 2021, South Oxfordshire District Council agreed to a motion to work with partners to explore the possibility of moving these and other high-voltage power lines underground, with a long-term goal of achieving this by 2050.
Health and Safety: The presence of the power lines has previously raised public concerns about potential health risks, particularly a possible link between electromagnetic fields (EMF) and childhood leukaemia, a topic explored in various studies. Health bodies state that EMF levels from overhead lines in the UK are below exposure limits and decrease rapidly with distance, with no conclusively demonstrated health risks from living nearby.
In a notable 2003 incident, a fence around the Ladygrove Lakes had to be earthed after it was found to be receiving an electric charge from the overhead lines, causing static shocks to people, including children on bikes.
Despite the historical concerns, the Ladygrove estate has been noted in the past for having one of the highest life expectancies of any council ward in England and Wales.
About this multi-cache:
At the published coordinates, you will be standing in front of a lamp post. The lamp post has a white sticker on it, with two letters followed by two numbers on it. What are they? Let the two letters be AB, and the two numbers be CD.
For the above two letters on the sticker, translate each letter to a number using A = 1, B = 2, ..., I = 9, J = 0, K = 1, ... method.
Now please look up and you will find another sign on the same lamp post. On the top of this sign there is a yellow warning symbol. The number of letters in the word immediately below the word "DANGER" is E.
Below this yellow warning symbol there is another blue symbol, with some white words below it. The total number of letters in the second word on the first line of these white words is F. And the number of letters in the last word on the bottom line is G.
The final coordinates are a short distance away at:
N51 ( A * C + B ) ( C + D - B ) . ( B * E / A ) ( F / G * ( B + C ) ) ( D * F / G )
W001 ( C ^ ( D / A ) ) ( E / ( G / A ) ) . ( F / ( A - C ) ) ( ( D / A ) ^ ( E - G ) ) ( ( C + F ) ^ ( D / G ) )
The checksum of all the digits in the final coordinates is 43.
Please also note:
As of January 2026, there is a loose structure at/near the GZ, so please be very careful and do not touch this loose structure. You will be searching for the cache at your own risk. You do not need to touch this loose structure in order to find the cache.
Please bring your own pen, and open & close the cache lid carefully so the cache and log book can survive longer.
Please also replace exactly as found due to obvious reason, and please be careful with the possible thorns and stinging nettles. Long sleeves, trousers, and gloves are recommended.
Thank you and enjoy GeoCaching!
FTF: Congratulations to wendykmj for their FTF on 29 January 2026!
