20 or so years ago a Mountain Goat killed a back packer in the Olympic National Park, Washington State, USA. I live about 5 miles from the north park boundary, it is on the Olympic Peninsula in the NW corner of Washington state.

The hiker was gored in the upper thigh and bled out. He was hiking solo, a search party found him a few days after he died. I have been in the area where the hiker met his death.

The Goats here have no fear and are notorious camp robbers, searching for anything containing salt like potato chips. I banged one over the head with a camera tripod as he was tearing up my back pack, after the chips in the pack.

Yea, a mature male is big, close to 400 pounds and armed with a pair of 10 inch daggers on the head.
