Thanks for the information on preserving the skull, I appreciate it. If I can get a digital camera I will post a picture sometime. As for where I found it; I was in unit 33. The skull is doesn't have any puncture wounds in it. I don't know how to judge of it's a big mountian lion or not but the skull is a little over 7" long and 5 1/2" wide. One of it's canine teeth is broken but the othe one is big enough that I wouldn't want to mess with it. I've seen lion tracks in this area but no live ones yet. thanks again for the info.
