This subject came up in another thread, so I decided to compile the incidents I know in the Smokies, the area I visit the most. There are always questions about why bears attack. These incidents don’t really answer that question.
With 14 million visitors each year and an estimated 1900 bears in the park, there are bound to be bear-human encounters. The vast majority of them are benign in nature, and the bears normally avoid contact. It is easy to surprise a bear in this densely vegetated park, and even when that happens the bear normally leaves with no incident. In my 32 years hiking in the park I have only seen bears on the trail twice, and heard a third. Bear scat is common, but actually seeing one is much rarer, at least it has been for me. The most recent was this summer, when there was a bear meandering around the trail on the lower part of the Rainbow Falls trail, a very popular tourist destination. The bear wandered back and forth across the trail for a bit, ignoring us. It finally ambled off into the woods. Later that same day when we were above the tourist attraction (Rainbow Falls) in very steep terrain, we rounded a corner and heard crashing sounds. It sounded like a boulder had come loose and was rolling down the slope. We waited for a bit before proceeding, and another solo hiker came down the trail and said a bear was running up the trail and when it saw him it jumped off the trail down the slope. It must have been running away from my daughter and me. The other hiker was glad to see us.
All backcountry camp sites have cables for hanging food, and you are required to use these cables. You are also required to use designated camp sites, which means there are hanging cables at all legal camp sites.
I am aware of seven predatory bear attacks in the park. I don’t count incidental contact like the time this last June when campers at a front country site had pet food improperly stored and a bear entered the tent to get it. A woman and her daughter were scratched in the encounter, but the bear was after the food, not the people. (The bear was captured and euthanized – the Park news release stated “The bear weighed approximately 350 pounds, which is not standard for this time of year, suggesting the bear had previous and likely consistent access to non-natural food sources,”). Nor the time several years ago when someone went missing while illegally collecting Ginseng. His friend did not report it for a couple of days, and a search resulted in finding his body with a bear acting aggressively. Autopsy results indicated he had died of an overdose, so the bear found the body and decided it was an easy meal.
Predatory attacks from oldest to newest:
02 October 1989, Chimneys picnic area. A woman was at the creek and heard noise behind her. She turned to see a bear that charged her. She ran but fell, and the bear grabbed her by the neck. A couple of others present used rocks and sticks to chase the bear off. She had a broken scapula and puncture wounds on her back and neck. This was a tagged bear that already had a history of aggressive behavior. Tourist feeding of bears in this area was a problem. The bear was released in another location, and then later it was euthanized.
21 May 2000, Little River trail above the junction with Goshen Prong trail. A woman and a man were hiking, while he was fishing up the stream. She hiked on ahead alone. Later as he fished his way up the stream he discovered her body and a sow with a cub nearby acting aggressively. The sow and the cub were both shot. Examination of the bears confirmed that they had fed on the woman. This was the first known fatality from a black bear attack in the Smokies.
11 August 2008, lower part of Rainbow Falls trail. A child was playing near a stream and a small male bear (86 lbs) attacked him. His father was able to pull the bear off, and the bear continued the attack. The bear was killed by rangers. The boy required staples and stitches, and the father had minor injuries. They were day hikers who had no food with them, though they had eaten KFC before starting on the trail.
06 June 2015, camp site 84 on the Hazel Creek trail. A bear grabbed a teenage boy from his hammock during the night. His father was able to chase the bear away (physically attacked the bear). There were significant, though not life threatening, injuries. The teen spent 5 days in the hospital. Rangers shot a bear at the site the day after the attack but were unable to track it due to darkness and a heavy thunderstorm. A few days later they caught another bear and euthanized it. DNA tests indicated that the euthanized bear was not the one that attacked the boy. They later found a bullet at the site with traces of bear sample and analyzed the DNA. Results were not definitive (poor sample) but there was a partial match with bear DNA recovered from the boy. They had properly stored food on the hanging cables.
10 May 2016, Spence Field shelter on the AT. A through hiker set up a tent a short distance from the shelter. A bear attacked him through the tent wall. He was able to get away and get to the shelter without serious injury (treated and released from the hospital – bites on leg). The bear returned and tore up the tent after he took refuge in the shelter. He had properly stored his food on the hanging cables. Rangers darted a 400 lb male bear at the shelter 3 days later and euthanized it since it was too large for them to fit a GPS collar and track it pending DNA results. They trapped two additional bears at the site over the next few days (200 lbs and 170 lbs) and collared them, but DNA results indicated than none of the three bears had attacked the hiker.
~08 September 2020, camp site 82 on the Hazel Creek trail. Hikers walked past the site on September 11th and noticed a tent there, and then saw a bear across the creek feeding on the body. Rangers killed the bear after seeing it scavenge on the body. It was unknown if the bear had killed him or had come across him after he died. The autopsy report released a year later indicated that the bear had indeed killed him.
18 June 2021, camp site 29 on the Maddron Bald trail. A teenage girl was pulled from her hammock during the night and mauled. Other family members were able to drive the bear away. She was airlifted out by a TN Air National Guard helicopter. Two bears were observed around the site after the attack, and a large male repeatedly tried to enter the site despite rangers’ attempts to scare it away. They shot the bear, and found that it had human blood on it. The family had properly stored food on the hanging cables.
I have not attempted to determine if the attacks are associated with good or poor mast crop yield years. I know that the bear encounters were low this past fall when there was an abundant mast crop.
An interesting side bar regarding relocating problem bears. Problem bears in the Smokies are sometimes relocated. Studies are being done to determine their survival after being relocated (preliminary results are that 2/3 are dead within 4 months). One recent case is revealing. A female was relocated in early June to a national forest in the SE corner of TN. Over the next 6 months it was tracked as it moved into Georgia, South Carolina, North Carolina, and then back into TN to the same campground where it had been captured, covering 1,000 miles. It kept going on its multi-state travels after this.
