I think the information here is really important and thanks for the advice. I'll use it the next time I go hiking.

I was at Washington Park and it is so surprising how much garbage is on the ground, especially the fact that Washington Rock is a national monument, more people should be enforcing littering.

Benchmarks are actual marks used by engineers, and are not hidden by geocachers. Geocachers hide containers, but benchmarks are like little disks thant were not meant to be hidden (or at least the engineers didn't think people would hunt for them when they were placed).
