“This is one mean cat”.
I agree and am familiar with this area. It’s mountainous and has been sparsely populated for many years. Towns of Arrowhead, Crestline, Running Springs and Big Bear, it’s been a recreational area for many years and thousands of people use the area winter and summer.
The bigger problem with cougars is in heavily populated areas that abut mountainous areas in So CA. Cougar numbers have increased greatly since they were protected in 1990.
