Benchmark Symbol

The triangle is the universal mapping symbol for any type of randomly located survey control point, which includes all geodetic markers, whereas the square is used for points that are not set at random locations, such as boundary corners. In fact, many surveyors refer to random control points as deltas, due to the shape of that letter of the greek alphabet.

I change the symbol for non-benchmark locations like vacation spots, common driving destinations, etc. to appropriate symbols.

 

I let the benchmarks get the default symbol. When I get a lot of them loaded in my GPS, I select for that type and delete them all in one shot.

 

This is of course after I've made sure to log them all on geocaching.com with the right date, whether found or not-found.
