Is there a book or some other resource on tracking animals? I realize most photographers set up blinds in areas where animals are likely to be seen. However, I oftentimes will be in an area where tracks are found and I would like to know how to determine their freshness to see if I could find that animal.
A couple of months ago I was photographing Clear Creek in Colorado (it's the one that feeds into the Coors brewery in Golden) and I saw some mountain lion tracks. I didn't know how fresh they were though they didn't look like they were recent but I thought that, had I been there when the lion was there, I could've been in trouble.
