Two Prominent Rocks

The Tuesday walking crowd were exploring Lowick Beacon which meant I could come and find a geocache that I'd  worked out some time ago. You were given the distance to three points some miles away and you had to work out where the cache was.   You remember this from geography , draw three circles and see where they intersect. You are in the little triangle somewhere.  That's where the cache should be.  We searched for a while with no luck. Was my calculation wrong? The hint was "between two prominent rocks".  Eventually we spotted these two and sure enough , there was the cache . We were the first people to find it since December 2021. Feeling very pleased with myself. Chris was too - her contribution was spotting the rocks.
