Here's some photos for ya...
This plant looks like maybe at first glance, just a cactus... but it drops these burrs that look just like the rocks, and then those blow around.... each with a serious barb on the end making removal a very painful process.
If your dog hits a load of these, the first they do is try to remove it with their mouth.... guess what happens next.
This is proof enough to me why no one lives there.
In Las Ciengas, there are none of these and it's no where near as rocky and much more private. Just food for thought.
