Here in my part of the world there are a lot of treeless hills, draws and rolling plains . When you get to looking around you will see on top of a lot of these hills there are a pile of rocks that were placed there by humans . We call these sheep herders monuments as the Bask sheep herders would set by them to watch the flocks of sheep and stay out of the wind , rain ,snow and sun . I think that they were already there before the Bask and that the Native Americans used them to watch their areas for intruders and game animals . I have used them to my advantage when looking for coyote as well . they break up your outline so you aren't sky lined they have been there for a lot longer then me or any of the animals so the animals are used to them and you have a great view of the surrounding country . Down on one of the ranches I worked for I was setting at one looking the country over when I noticed a winter Indian camp , they had stones laid out in two rings so they could put one tepee inside of another against the wind and weather that tells you it was a winter camp . So after I was done looking I wandered down to the camp . As I looked around down the hill I saw a small pile of rocks and wandered on down there also . When I got there I saw laid out with stones 3 5 1853 and a grave . In my mind there lies an unknown solider of the period . I found these things because I was hunting coyote and was able to get to places that most can't because I was good to the ranchers and did them a good job so then they learned to trust me .
