Large trout, could see them in the clear water!. Never encountered a lion, nor foot prints. Likely there were more scarce then, and more afraid.
Later years, due to increased development, had to park at the Cool bridge,(whole 'nother story) and walk upstream to hike and fish. Always armed, always paired or more, never saw a cat. Walked noisily and with purpose, no sneaking through the underbrush.
They are no longer afraid due to no hunting, and getting bold.
They come down the dry river bed into the south east parts of the county and kill/steal livestock.
Nowadays always armed, cocked and locked, chest holster when fishing the streams and rivers in the foothills.
There are more two-legged dangers out in the wilderness these days, too. I trust them less than mountain lions or bears. None of these animals speak much English. Staying armed with one in the chamber may just save your life.
