The cache container is not at the posted coordinates, but it is within 2.5km.
I was talking recently with other cachers about the wide variety of cache types and D/T ratings for caches in the Durham area, and one of them commented that the D5/T1 combination is very rare. That was my inspiration for putting this listing together: combining a difficult puzzle with a simple retrieval.
In order to get the coordinates, it will be necessary to solve the paint-by-numbers puzzle below and complete the grid. Each of the numbers shown indicates the number of consecutive blocks in that row or column that should be filled in, but you have to use logic to figure out how much space to leave between each set of blocks (or single blocks, in the case of the "1" indicators).
No hints to start off, but I will add some once "first to find" is gone, or a sufficient interval has gone by.
