Yes, I am attempting to use the "Blazed" trees to follow a line. The marks are all and only on the due west side of the trees. They seem to be all the same mark, which was a scar made with a hatchet in the form of a circle with a deep cut line going up from the top of the circle. These were painted red, which has become infused with the new bark. It is amazing to me that i had never noticed most of these blaze marks till now, and with my eye now trained to see them, I am seeing lots of them. This will make the job much, much easier.
I'm in Central Western Oregon about 16 miles South-East of Eugene. I have no urgent reason for finding this marker. But 10 years down the line, I will probably need to re-survey and this time lay down some permanent stakes. Which if I have anything to offer to the readers of TBN, is to set those when it is clear where your legal line is just after a survey. I am attempting to freshen up the line as i found an abandoned bow hunting deer stand, that appears to be on my property, but might not be. The terrain is very confusing and every time I try to visualize this property line it doesn't make sense when I'm following it. Its like one of those fun houses built on a 30 degree angle.
I have a handle on what my questions really are now.
1. Is there a standard to blazing marks on trees? Do these marks, if different from each other, have any extra meaning. For instance, this morning I found a mark that was more of a diamond shape, and not the circle with the line out of the top. It is the Western most tree, and only this morning did I notice it. I'm guessing that this is ether the Start of the Blaze, or that this tree is ON the boundary line.
2. Is there a rule of thumb as to how far a blazed tree can be to the actual boundary line. There are no trees in the verbal description of the property, only set pipes, a USGS Monument, distances and degrees. I'm assuming that the Blaze marks are just rough guides and have no legal weight. They are there just as a guide line for timber sales or other activities that don't have to be right on the legal line.
3. Not a question, but thank all you guys for replying, as it helped me focus on a method to relocate this pipe. GPS will not help to locate, but once I have found it I'm going to have it registered some how. Metal Detector is turning out to be useless, as this marker is with in throwing distance from a 90 year old road.

So far, I have found more beer cans than I care to enumerate.
