Found 2 Benchmarks

[+Tim M CPA]

I found two, one is easy because it's at the enterance of the Yellow Suffern Bear Mtn Trail in Harriman Park NY. The other was harder. It is off the trail at the top of the kitchen stairs (a part of the trail once you get up to the top of the mountain and proceed down the hollow and then at the rock fault the ascension is the stairs) which is on the yellow trail northbound. The actual hidden marker divides the park with the utility company property and it is found if you go toward the rocks, i took photo of , at the top of the kitchen stairs,and a little north on the path. Good luck , let me know if you find this one too.
