The Challenge: Log a total of 20 different benchmarks types.
A benchmark's type can be found on a benchmark's description page, as viewed on geocaching.com. You will need to log at least 20 benchmarks in order to qualify for this challenge. Each benchmark must be classified as a different marker type. This could include: bench mark disks, survey disks, triangulation station disks, reference mark disks, metal rods, horizontal control disks, azimuth mark disks, "type not specified," and a large variety of others. You may not be able to find all 20 types in one area.
-You must use 20 distinct benchmark types for your qualifying benchmarks, no repeats.
-All past benchmark finds count.
-The benchmark's type must be listed on the benchmark's webpage on geocaching.com.
-Only benchmarks listed on geocaching.com can qualify for this challenge.
-The types "Type Not Specified" and "NGS Benchmark" are the same title, please label only as "Type Not Specified" in your log.
-Photo evidence is not required, but I would be glad to see pictures posted on the pages of the benchmarks that you use for qualifiers.
-If your qualifying benchmarks do not satisfy these requirements, your log is subject to deletion.
-Please format your finds in "Benchmark Type - Benchmark ID / Designation / Date Found" format, as I have done below.
