+snowfreak37 Posted May 26, 2009 Share Posted May 26, 2009 This benchmark is not really of any importance to me except it's fairly close by and its proving to be more difficult than I thought. The first time out I only had my GPS'r and the datasheet. Even though the location is scaled I was hoping to find this rock outcrop with my eyes only. That didn't work so I walked to the the west end of the north guard rail and walked roughly 149.5 feet to the east(I have around a 3 foot stride) and walk roughly 54.2 feet north from the center of the road. There is a small portion of exposed rock outcrop and I kick away some of the loose dirt and find nada. Today I went out with my handy dandy measuring wheel and went an exact 149.5 (which was within a foot of my rough calculations the first time) and measured an exact 54.2 feet. The other measurement from the telephone pole is obsolete they have been moved since 1973. In fact its quite possible that the guardrail has been lengthened or shortened since 1973. However this is the only rock outcrop for a distance, so I believe I'm in the right area but quite a bit of the rock outcrop is covered with 3-5 inches of soil, grass, brush which leads me to the metal detector question. I can borrow a friends metal detector and it has the ability to detect different metals. What are these benchmarks generally made of? I have never used a metal detector before so I guess I am looking for some input on what to expect. It's got to be better than digging through the dirt. On a seperate note when I measured from the center of the road I used my measuring wheel and the benchmark is down a fairly steep embankment. If I took a piece of string and cut it 54.2 feet it would put me further north than my measuing wheel. Not sure if the measurment is line of sight (cut string) or how I am doing currently doing it. Thanks for any input. Quote Link to comment
