The Dakota Ridge trail comes off the ridge and down into this little “meadow.” It is not clear whether this meadow is natural or an atrefact of previous mining.

The thing to see here is the two women and their unleashed dogs. I had previously talked to them and asked them to leash their dogs. Four minutes before I took this photo (by the timestamps on the photo), I took the photo of the rattlesnake beside the trail.
