I live in Central Oregon and have spent a lot of time in the Desert South and East of Bend...The northern corner of the great basin. Over the years I have found and explored many historic sites way off the beaten path. Stone homesteads, indian sites, homestead era townsites, moonshine still sites, military camps etc. Mostly over the years I was just exploring and hunting. I've read a lot about the early history when the military was tasked with suppressing indian activities and exploring and mapping the region. I spent time reading about events, and then would go out and search for (and sometimes discover) the sites. When I first started exploring the most remote country many homesteads and townsites still had standing structures. Over the years most all of the buildings have collapsed so now most wouldn't even know they were there. I recently picked up a metal detector (and just joined this forum). I've caught the bug for sure. A friend and I went out last weekend and detected the site of a military/indian skirmish that is on a ranch that some friends of mine own. I had discovered the site years ago. We found several large caliber rimfire shell casings, a brass button, a nice complete arrowhead, and a couple of broken points. Nothing too impressive but it's just amazing to know a piece of history, and then find the actual evidence of what unfolded.
Basically if you drive out east of Bend on Hwy 20 until you get past Millican and Pine Mountain you will be in country that is full of indian, early military, and homestead era history. If you get off the highway and start following two track dirt roads there is a lot to discover.
Basically I only know 1 other person who is interested in this type of thing and we don't get much time to explore together. I'm looking forward to hopefully connecting with some other folks in my area who share the interest.
