If you are talking about the photo in the Tioga publication, the person quoted as saying the picture was of a “ yearling male “ was the person who provided the photo. It would not have been much trouble to track down a biologist who could have given a professional opinion.
While the coloration looks about right and the cat is muscular with a long tail, there is no scale comparison in the photo. I would be willing to bet this animal weighs much less than 30 lbs.
Male mountain lions can get over 100 lbs. The paws and head look too small and delicate. The ears look a lot like what you would see in a domestic cat as well.
My guess would be that it could be an escaped pet, either a big Abyssinian or maybe a Jungle Cat hybrid, which is becoming more popular in the pet trade. Hybrid cats are often dumped by owners when they find out these creatures behave more like wild animals than pets, especially when it comes to their bathroom habits.
