Bobcat....walked around in the dark, in and out if the canyon and all over the management area for 30 years. No mountain lions. Grandparents owned the Canyon Land park before they sold it and it shut down. They DID release all the animals in the zoo portion by opening the enclosures. Interesting sounds at night in the canyon after that for awhile to here my dad and the other older local gents talk about it. Would have been late 60s into the 70s.
